Can You Get a Construction Loan for Major Renovations or Extensions?

Getting a Construction Loan for Major Renovations or Extensions

Yes, you may be able to get a construction loan for major renovations or extensions in Australia, but lender treatment depends on the scope of work.

A small cosmetic renovation may be handled as a cash-out refinance or loan increase. A major renovation or extension may need a construction loan with progress payments, a fixed-price building contract, council approval, an as-if-complete valuation and evidence of funds to complete.

This distinction matters. Adding a second storey, extending external walls, adding rooms, rebuilding part of the home, or completing structural work is usually assessed very differently from repainting, replacing flooring, updating a kitchen or renovating a bathroom.

This guide explains how lenders may assess construction loans for major renovations and extensions, based on current policy research.

Can you get a construction loan for major renovations?

Yes, with the right lender.

A lender may consider a construction loan for major renovations if:

• the property is acceptable security
• the renovation is clearly documented
• the builder is licensed or registered
• the building contract is acceptable
• the contract is fixed price, where required
• council approval is in place or obtainable
• the completed valuation supports the loan
• progress payments can be managed
• funds to complete are verified
• the borrower can afford the loan
• the LVR fits lender policy

Major renovation lending is possible, but it usually needs more documentation than a normal refinance.

Can you get a construction loan for an extension?

Yes.

Extensions are commonly assessed under construction lending where they involve structural work or changes to the existing dwelling.

An extension may include:

• adding bedrooms
• adding bathrooms
• extending the living area
• adding a second storey
• adding a garage
• enclosing or extending part of the building
• adding a new wing
• increasing the building footprint
• adding a self-contained area
• building an ancillary dwelling or granny flat

If the lender relies on the completed value of the property, progress payments and construction policy may apply.

When is a renovation considered major?

A renovation is more likely to be considered major if it involves:

• structural changes
• external wall changes
• additional rooms
• additional floors
• roofline changes
• foundation or footing work
• load-bearing wall changes
• council approval
• engineering
• building permits
• progress payments
• reliance on the completed value
• a licensed builder contract
• large project cost

Major renovations are often treated more like construction than simple home improvements.

When is a renovation considered cosmetic?

A renovation is more likely to be considered cosmetic if it involves:

• painting
• flooring
• kitchen refresh
• bathroom update
• new appliances
• cabinetry
• non-structural landscaping
• minor repairs
• internal cosmetic upgrades
• window coverings
• light fittings
• minor non-structural improvements

Cosmetic renovations may not need construction-style progress payments if the lender is not relying on the future improved value.

Why does the difference matter?

The difference matters because the loan structure can change.

For cosmetic renovations, a lender may allow funds to be released as cash out or a standard loan increase.

For major renovations, a lender may require:

• building contract
• plans and specifications
• council approval
• progress payment schedule
• builder licence
• valuation as if complete
• inspections
• funds-to-complete evidence
• construction loan setup

The more structural the work, the more likely construction policy applies.

Can renovation funds be released as cash out?

Sometimes.

Some lenders allow cash out for renovations where the LVR is within policy and the lender is satisfied with the purpose.

This may work for:

• non-structural renovations
• cosmetic upgrades
• home improvements
• smaller projects
• works not requiring progress payments
• loans supported by the current as-is value

The lender may ask for quotes, a contract, a list of works or simply detailed commentary, depending on policy and LVR.

When are progress payments required?

Progress payments are more likely to be required where:

• the renovation is structural
• the extension changes external walls
• council approval is needed
• the lender relies on the as-if-complete valuation
• the works are large
• the loan amount exceeds the current as-is value
• the build is staged
• a licensed builder is contracted
• the property may not be habitable during works
• the lender wants control over funds

Progress payments help the lender release funds as value is added to the property.

Can renovations be funded without progress payments?

Yes, sometimes.

Some lenders may allow renovation funds without progress payments where:

• LVR is acceptable against current value
• renovations are non-structural
• the amount is within cash-out policy
• loan purpose is acceptable
• borrower profile is strong
• the lender does not need the future value to support the loan
• no construction-style contract is required

For example, if you have strong equity and only need funds for cosmetic works, the lender may treat it as cash out rather than a construction loan.

What if the loan relies on the completed value?

If the loan relies on the completed value, construction policy is more likely.

An as-is valuation looks at the property today.

An as-if-complete valuation estimates the value after the renovation or extension is finished.

If the loan only works because of the future value, the lender will usually want more control over:

• construction documents
• progress payments
• builder contract
• inspections
• funds to complete
• completion evidence

This is common for major renovations and extensions.

What is an as-if-complete valuation?

An as-if-complete valuation estimates what the property will be worth once the renovation or extension is complete.

The valuer may review:

• current property
• proposed plans
• specifications
• building contract
• scope of works
• location
• comparable sales
• expected marketability
• completed floor area
• quality of improvements

The lender may use this valuation to calculate LVR.

What if the as-if-complete valuation is lower than expected?

You may need more cash or a smaller loan.

A valuation shortfall can happen if:

• the renovation cost is higher than market value added
• the home is overcapitalised
• the area does not support the finished value
• comparable sales are weaker
• design is too personalised
• site issues reduce value
• works are not fully included in the valuation

The lender may base LVR on the lower valuation, not your total project cost.

Can you overcapitalise on a renovation?

Yes.

Overcapitalising means spending more on the renovation than the market recognises in value.

For example, spending $400,000 on an extension does not guarantee the property value increases by $400,000.

This can be a problem if you need to borrow most of the renovation cost.

Lenders care about the completed market value, not just the invoice amount.

Can you borrow 95% for major renovations?

Possibly, but it can be difficult.

High-LVR renovation construction depends on:

• lender policy
• mortgage insurance availability
• borrower profile
• property value
• renovation type
• builder contract
• completed valuation
• funds to complete
• whether the work is structural
• whether the loan is owner-occupied or investment

Some lenders may allow high-LVR construction with a licensed builder and fixed-price contract. Other renovation scenarios may be capped lower.

Can you borrow 80% for major renovations?

Often, 80% LVR is more realistic.

At or below 80% LVR, lenders may be more flexible because mortgage insurance is usually not required.

However, the lender may still need:

• renovation documents
• building contract
• valuation
• progress payment schedule
• council approval
• funds-to-complete evidence

An 80% LVR does not avoid construction policy if the works are major or structural.

Can renovation cash out be allowed above 80% LVR?

Sometimes, but policy can be stricter.

Some lenders allow cash out for renovation purposes above 80% LVR with mortgage insurance, subject to conditions.

Other lenders restrict cash out heavily above 80% or allow only limited cash out for costs.

At higher LVRs, the lender and mortgage insurer may want more detail about the renovation purpose and property value.

Can renovation cash out be capped?

Yes.

Cash-out policy may cap:

• maximum LVR
• maximum cash-out amount
• acceptable purposes
• required evidence
• whether mortgage insurance is available
• whether supporting documents are needed
• whether funds can be used for structural renovations

If the renovation amount exceeds the lender’s cash-out comfort, the loan may need to be structured as construction.

Can you use a standard home loan for major renovations?

Sometimes, but not always.

A standard home loan or refinance may be possible if the current property value supports the loan amount without relying on the renovation being completed.

For example, if your property is worth $1,000,000 and you owe $400,000, you may be able to release equity for renovations within lender cash-out policy.

However, if the loan depends on the future improved value, a construction loan is more likely.

Can you use equity to renovate?

Yes.

Equity is commonly used to fund renovations.

Equity may be released through:

• refinance
• loan increase
• top-up
• split loan
• construction loan
• line of credit, where suitable
• offset or redraw funds

The right structure depends on the renovation size, LVR, purpose, lender policy and whether progress payments are needed.

Can you use redraw for renovations?

Yes, if you have redraw funds available and your loan terms allow it.

Using redraw may avoid a new application if the funds are already available.

However, if the renovation is structural and affects the lender’s security, you should still check whether lender consent is needed, especially if the property is mortgaged and significant work will occur.

Can you use offset savings for renovations?

Yes.

Using savings in an offset account can be simple because you are using your own funds.

However, you should still plan carefully for:

• total project cost
• contingency
• temporary accommodation
• council approvals
• insurance
• cost overruns
• whether the property remains habitable

Even cash-funded major works may require council and insurance compliance.

Can you use a line of credit for renovations?

Possibly.

A line of credit can provide flexibility for staged renovation costs.

However, it may not be suitable for everyone because:

• interest can accumulate
• spending discipline is required
• lender cash-out policy still applies
• repayments may be interest-only
• rates may be higher
• the lender may question structural renovation purpose

For major renovations, a construction loan may provide more control.

Can you use a personal loan for renovations?

Possibly, but it may be expensive and reduce borrowing capacity.

A personal loan may suit small renovations, but major extensions usually need larger amounts and longer terms.

Personal loans can create issues because:

• repayments are higher
• interest rates are usually higher than home loans
• loan terms are shorter
• serviceability reduces
• future refinance may be harder

For structural works, mortgage-backed finance is often more suitable if available.

Can you use credit cards for renovations?

This is risky.

Credit card use for major renovations can create:

• high interest costs
• reduced borrowing capacity
• poor bank statement conduct
• cash-flow pressure
• repayment stress
• difficulty proving funds to complete

Small purchases may be manageable, but relying on credit cards for major works is usually not a strong lending strategy.

Can you use a construction loan for a second-storey addition?

Yes, with some lenders.

A second-storey addition is usually a major structural extension.

The lender may require:

• approved plans
• engineering
• builder contract
• fixed-price contract
• council approval
• valuation as if complete
• progress payments
• insurance
• funds-to-complete evidence

A second storey is usually not treated as a simple cash-out renovation if the lender relies on the improved value.

Can you use a construction loan to add bedrooms?

Yes.

Adding bedrooms usually changes the dwelling’s size and layout.

The lender may assess:

• builder contract
• plans
• council approval
• valuation uplift
• progress payment stages
• whether the property remains habitable
• funds to complete
• LVR

Adding bedrooms can improve value, but the lender still checks whether the cost is justified.

Can you use a construction loan to add a bathroom?

Possibly.

A bathroom addition can be structural or non-structural depending on the scope.

If it is part of a major extension, construction policy may apply.

If it is a simple internal renovation funded from existing equity, the lender may treat it as cash out.

The distinction depends on whether the works require building approval, structural change and reliance on completed value.

Can you use a construction loan to extend the kitchen or living area?

Yes, if the extension is structural or significant.

A lender may request:

• scope of works
• building contract
• plans
• specifications
• council approval
• valuation
• progress payment schedule

If the work is only a kitchen replacement within the existing footprint, cash-out policy may be enough.

Can you use a construction loan for a garage addition?

Possibly.

A garage addition may require council approval and structural work.

The lender may consider:

• whether it is attached or detached
• whether it is included in valuation
• builder contract
• plans
• progress stages
• access and driveway works
• insurance
• marketability

If the garage is part of a larger extension, construction lending is more likely.

Can you use a construction loan for a granny flat?

Possibly.

A granny flat or ancillary dwelling can be treated as construction or major improvement.

The lender may assess:

• council approval
• whether the granny flat is self-contained
• whether it can be rented
• builder contract
• valuation impact
• rental income treatment
• number of dwellings on title
• property zoning
• LVR

Some lenders have specific rules for ancillary dwellings, so this should be checked early.

Can you use a construction loan for a pool?

Sometimes, but a pool alone may not be treated the same as a major residential extension.

Some lenders may allow pool funding as cash out if LVR and purpose policy allow.

If the pool is part of a larger construction project, it may be included in the construction contract and valuation.

However, pools can be viewed as discretionary and may not add value equal to cost.

The lender may require the core dwelling works to be fully funded first.

Can you use a construction loan for landscaping?

Possibly, if landscaping is part of the approved project and valuation.

Landscaping may be included where it is required for:

• council approval
• drainage
• retaining walls
• access
• completion
• safety
• marketability

Optional landscaping may need to be funded separately, especially if the lender is focused on completing the dwelling.

Can you use a construction loan for retaining walls?

Yes, if required and properly costed.

Retaining walls can be important for sloping blocks, extensions and site stability.

A lender may want retaining wall costs included in the contract or funds-to-complete calculation.

If retaining walls are required but excluded from the contract, the project may be underfunded.

Can you use a construction loan for driveway works?

Possibly.

Driveways may be important for access, council requirements and valuation.

If driveway works are part of the approved renovation or extension, they should be included in the contract or cost breakdown.

If excluded, the lender may ask how they will be funded.

Can you use a construction loan for structural repairs?

Possibly.

Structural repairs may include:

• foundation repairs
• subsidence repairs
• roof structure repairs
• termite damage repairs
• retaining wall replacement
• water damage rectification
• fire damage repair
• major wall or slab repairs

The lender will assess whether the property is acceptable security and whether the works will restore or improve marketability.

Can you renovate a property with existing defects?

Possibly, but defects can affect approval.

If the property has defects, the lender may consider:

• current value
• whether it is habitable
• cost to repair
• completed value
• insurance issues
• builder scope
• funds to complete
• valuation comments
• whether defects are structural

If defects are severe, the lender may require works to be completed before normal lending terms are available.

Can you borrow to repair fire or storm damage?

Possibly.

If the property has been damaged, the lender may assess:

• insurance proceeds
• scope of repair
• builder contract
• current value
• completed value
• whether the property is habitable
• funds to complete
• lender interest in insurance payout
• progress payment structure

Insurance money can help, but the lender still needs a workable finance structure.

Can insurance proceeds be used for renovations or rebuilds?

Yes, where available.

The lender may need evidence of:

• insurance payout
• insurer scope of works
• builder quote
• funds received or controlled
• remaining cost to complete
• whether the lender is named on the insurance policy
• how payments will be released

Insurance proceeds can reduce the loan needed, but they may be controlled by the insurer or lender.

Can you renovate while living in the property?

Sometimes.

Whether you can live there depends on the scope of works.

You may not be able to live there if:

• kitchen or bathrooms are removed
• electricity or water is disconnected
• major structural work is occurring
• asbestos is present
• roof or external walls are removed
• safety risks exist
• council or builder prohibits occupancy

If you need to rent elsewhere, the lender may include that cost in servicing.

Does temporary accommodation affect borrowing power?

Yes.

During major renovations, you may need to pay:

• rent
• mortgage repayments
• construction loan interest
• storage
• moving costs
• utilities
• insurance
• living expenses

This can reduce borrowing power and increase cash-flow pressure.

The lender may ask how you will manage the renovation period.

Can rental income be used during renovation?

Only if it will continue and is acceptable.

If the property is an investment and tenants must move out during works, rental income may stop.

The lender may assess:

• vacancy during renovation
• expected rent after completion
• rental appraisal
• construction timeline
• holding costs
• borrower capacity to cover repayments

For major investment renovations, the loss of rent can materially affect servicing.

Can you renovate an investment property with a construction loan?

Yes, with some lenders.

The lender may assess:

• current rental income
• rent during works
• expected rental income after completion
• renovation cost
• completed valuation
• LVR
• borrower serviceability
• interest-only request
• construction timeline
• whether tenants remain in place

Investment renovation loans can be approved, but cash flow needs careful planning.

Can rental income after renovation be used?

Possibly.

The lender may use a rental appraisal or valuer-assessed rent after completion, depending on policy.

However, they may also consider whether rent stops during the construction period.

If the loan only services by using future rent, the lender may require strong evidence that the completed rental income is realistic.

Can you use Airbnb income after renovation?

Possibly, but lender treatment varies.

If the renovation is intended to increase short-term rental income, the lender may ask:

• whether short-term letting is allowed
• current income evidence
• projected income evidence
• market rent
• tax return history
• management statements
• whether the property remains standard residential security

Short-term rental projections may be treated more conservatively than ordinary residential rent.

Can you renovate a holiday home?

Possibly.

A lender may assess:

• property use
• location
• valuation
• renovation scope
• completed marketability
• rental income, if any
• borrower serviceability
• LVR

Holiday homes in remote or seasonal markets may face tighter valuation and LVR review.

Can you renovate a rural residential property?

Possibly.

The lender may assess:

• land size
• zoning
• access
• services
• current dwelling
• proposed works
• completed value
• marketability
• whether the property is income-producing
• LVR

Major renovations on rural residential property may need more detailed valuation and funds-to-complete evidence.

Can you renovate a heritage-listed property?

Possibly, but it can be more complex.

Heritage controls may affect:

• approvals
• materials
• cost
• construction timeframe
• builder requirements
• valuation
• marketability
• contingency

A lender may require strong documentation because heritage renovations can cost more and take longer.

Can you renovate a property with unapproved works?

Possibly, but unapproved works can create problems.

The lender may ask:

• are the existing works being retained or removed?
• has council approval been obtained?
• can retrospective approval be obtained?
• will the renovation fix the issue?
• does the valuation include or exclude the unapproved works?
• is insurance affected?

Unapproved works should be reviewed by your solicitor, builder and broker before applying.

Can you renovate a leasehold property?

Possibly, but leasehold adds another layer.

The lender may assess:

• lease term
• lease conditions
• approval rights
• title type
• whether improvements are allowed
• completed valuation
• LVR
• lender leasehold policy

Renovating leasehold property is more specialised than renovating ordinary freehold property.

Can you renovate a strata unit?

Possibly, but strata approval may be needed.

The lender may assess the loan purpose and valuation, while your solicitor or strata manager may need to confirm:

• by-law approval
• owners corporation consent
• wet area rules
• noise restrictions
• common property impacts
• structural approval
• insurance

Major unit renovations can be difficult if they affect common property or building structure.

Can you renovate an apartment with a construction loan?

Possibly.

Apartment renovations are often funded as cash out if they are cosmetic and supported by current value.

Major apartment renovations may require more documentation if:

• structural walls are affected
• wet areas move
• strata approval is required
• building systems are affected
• valuation relies on the completed works
• costs are large

The lender and strata rules both matter.

Can you renovate a duplex or dual occupancy?

Possibly.

A lender may consider:

• number of dwellings
• title structure
• whether works affect one or both dwellings
• rental income
• valuation method
• council approval
• funds to complete
• LVR

If the renovation creates a second dwelling or changes occupancy, the lender may apply more detailed policy.

Can you use a renovation loan to create a second dwelling?

Possibly, but this may become construction of an ancillary dwelling, dual occupancy or multi-dwelling project.

The lender may ask:

• is the second dwelling approved?
• will it be separately titled?
• will it be rented?
• will it be sold?
• is subdivision planned?
• how many dwellings will be on one title?
• how will valuation be completed?
• is the project development-style?

This can be more complex than a standard extension.

Can you renovate to subdivide later?

Possibly, but lender treatment may be cautious.

If the project is part of a subdivision or development strategy, the lender may assess whether it is still ordinary residential lending.

They may consider:

• subdivision approval
• number of dwellings
• intention to sell
• construction complexity
• borrower experience
• valuation in one line
• funds to complete
• development risk

Some projects may require specialist or development finance.

Can you renovate and sell immediately?

This can be harder.

If your strategy is to renovate and sell for profit, the lender may view the project as speculative or development-style.

Some residential construction policies exclude loans where the borrower’s income or repayment strategy relies on development and sale of the security property.

If the plan is to renovate and flip, disclose it upfront.

Can owner-builders get renovation construction loans?

Sometimes, but lender options are limited.

If you are managing major structural renovations yourself, the lender may treat the project as owner-builder construction.

This can mean:

• lower LVR
• no mortgage insurance
• reimbursement-style drawdowns
• extra inspections
• more funds required upfront
• quantity surveyor reports
• tighter documentation

Using a licensed builder under a fixed-price contract usually provides more options.

Can you use a licensed builder for major renovations?

Yes, and this is usually preferred.

A licensed builder under a fixed-price contract can make the application stronger because the lender can review:

• builder licence
• contract price
• progress stages
• insurance
• warranty cover
• build timeframe
• plans
• specifications
• funds to complete

For structural renovations, this is often the cleanest finance pathway.

Is a fixed-price contract required?

Often, yes.

A fixed-price contract helps the lender confirm:

• total cost
• progress payment stages
• builder obligations
• inclusions and exclusions
• funds to complete
• valuation assumptions
• borrower contribution
• risk of cost overruns

Cost-plus renovation contracts can be more difficult.

Can you use a cost-plus contract for renovations?

Possibly, but it is more restrictive.

A cost-plus renovation contract may be accepted by some lenders at lower LVR or with extra evidence.

The lender may require:

• quantity surveyor report
• initial costing report
• stronger contingency
• lower LVR
• more inspections
• evidence of surplus funds
• no mortgage insurance reliance

Cost-plus contracts are difficult because final cost is uncertain.

Can a builder quote be enough?

For small cash-out renovation loans, sometimes.

For major renovations or extensions, a builder quote alone may not be enough.

The lender may need:

• signed contract
• plans
• specifications
• council approval
• progress payment schedule
• valuation
• builder insurance
• funds-to-complete evidence

A quote helps start the conversation, but it may not be enough for full approval.

Can you apply before council approval?

Possibly.

A lender may issue conditional approval subject to council approval or building permit.

However, if council requires changes, the lender may need to reassess:

• build cost
• design
• valuation
• timeline
• funds to complete
• contract
• progress stages

Construction funds may not be released until approvals are in place.

What approvals might be needed?

Major renovations may need:

• development approval
• building permit
• construction certificate
• council consent
• engineering approval
• strata approval
• heritage approval
• bushfire approval
• flood-related approval
• tree removal approval
• occupancy certificate at completion

The approval pathway depends on the property and work.

What if approvals are delayed?

Approval delays can affect:

• loan approval validity
• builder price validity
• valuation validity
• construction start date
• progress payment timing
• rental or temporary accommodation costs
• interest costs
• project budget

If approvals are likely to take time, build that into the finance plan.

What if the builder’s price expires?

If the builder’s price expires before approval or construction starts, the lender may ask for updated pricing.

This can affect:

• loan amount
• LVR
• valuation
• funds to complete
• serviceability
• borrower contribution
• mortgage insurance

Do not assume the original quote remains valid indefinitely.

Can build costs increase during renovations?

Yes.

Renovations are particularly prone to cost increases because existing structures can hide problems.

Unexpected issues may include:

• old wiring
• plumbing defects
• asbestos
• termite damage
• rotten framing
• foundation movement
• drainage problems
• non-compliant previous works
• structural defects
• access issues

A contingency is very important for major renovations.

Can variations be financed?

Sometimes.

Variations may be financed if:

• the lender approves them
• LVR remains within policy
• serviceability still passes
• valuation supports the change
• funds to complete remain sufficient
• variation documents are signed
• mortgage insurer accepts the change, if applicable

If not, the borrower must fund variations from savings.

What if variations are optional upgrades?

Optional upgrades may need to be funded from your own cash.

Examples include:

• upgraded benchtops
• premium appliances
• higher-end flooring
• additional landscaping
• upgraded lighting
• luxury bathroom fixtures
• pool extras
• smart home features

The lender may prioritise completing the core approved works.

Can you increase the loan during renovations?

Possibly, but approval is not guaranteed.

A loan increase may require:

• updated serviceability
• updated valuation
• new credit approval
• LVR review
• mortgage insurer approval
• variation evidence
• revised funds-to-complete calculation
• current bank statements

If your income, credit conduct or valuation has changed, the increase may be declined.

What if you run out of funds during renovations?

This can be serious.

If funds run out, the project may stop before completion.

The lender may not release further funds unless a loan increase is approved.

Options may include:

• use savings
• reduce scope
• delay optional works
• renegotiate with builder
• provide gift funds
• sell assets
• apply for loan increase
• refinance after completion

Running out of funds can affect property value and habitability.

Does the borrower contribution get used first?

Often, yes.

For construction-style renovation loans, some lenders require the borrower’s contribution to be used before lender funds.

This means your cash contribution may be paid into the project early.

You should understand:

• how much cash you must contribute
• when it must be contributed
• which stage lender funds begin
• whether grants or sale proceeds count
• how variations will be funded

Cash-flow planning is essential.

Can the lender pay the builder directly?

Often, yes.

For construction-style progress payments, the lender may pay the builder directly after receiving:

• invoice
• borrower authority
• progress inspection
• required documents
• evidence funds remain sufficient

This is different from cash-out renovation funding, where funds may be released to the borrower.

Can the lender release all renovation funds upfront?

Sometimes for cash-out loans, but usually not for construction-style major renovations.

If progress payments apply, the lender will release funds in stages.

This protects the lender and borrower by ensuring funds are matched to completed work.

Major structural renovation funds are less likely to be released all upfront.

What are typical renovation progress stages?

Renovation progress stages can vary more than new builds.

Depending on the contract, stages may relate to:

• deposit
• demolition or strip-out
• structural works
• frame
• lock-up
• services rough-in
• fixing
• wet areas
• completion
• final certification

The lender may adapt stages to the scope of work.

Are renovation progress payments different from new build progress payments?

Sometimes.

A renovation may not fit standard slab, frame, lock-up and fixing stages.

For example, an extension may include demolition, temporary works, structural steel, roof tie-in and internal fit-out.

The lender may need a clear progress payment schedule that matches the renovation contract.

Are inspections required?

Often, yes.

For major renovation construction loans, the lender may require inspections before progress payments.

Inspections may confirm:

• stage reached
• work completed
• value added
• cost to complete
• whether funds remain sufficient
• whether completion is likely

A lender inspection is not the same as a full building quality inspection.

Should you get independent inspections?

Yes, it can be wise.

Independent inspections may help identify defects at key points.

For major renovations, useful inspection stages may include:

• demolition or strip-out
• structural stage
• framing
• waterproofing
• pre-plaster
• fixing
• practical completion

The lender’s inspection protects the lender. Your independent inspector protects you.

Can renovations start before loan approval?

This can be risky.

Starting before finance approval can create problems if:

• lender refuses the project
• work is already partly complete
• valuation is harder
• invoices have already been paid
• inspections cannot verify earlier stages
• funds to complete are unclear
• the property becomes uninhabitable
• builder payment schedule does not match lender policy

Ideally, finance should be approved before major works start.

Can you refinance halfway through renovations?

Usually, this is difficult.

A new lender may be reluctant to finance a partially completed renovation because:

• work quality is uncertain
• cost to complete is unclear
• current value may be reduced
• property may be uninhabitable
• builder disputes may exist
• approvals may be incomplete
• insurance may be unclear

Plan the finance structure before work begins.

Can you switch builders during renovation?

Possibly, but lender approval may be needed.

The lender may ask for:

• new builder contract
• new builder licence
• updated insurance
• updated cost-to-complete statement
• revised valuation
• explanation for builder change
• progress inspection
• funds-to-complete evidence

Changing builders can delay progress payments and increase cost.

What if the builder goes bust?

Builder insolvency can be a major problem.

If the builder fails, you may need:

• insurance claim
• new builder
• revised contract
• cost-to-complete report
• updated valuation
• lender reassessment
• legal advice
• extra cash
• temporary accommodation extension

The lender may pause drawdowns until the project is reassessed.

What if there is a builder dispute?

A dispute can delay finance and construction.

If you dispute a progress claim, you may need to:

• withhold borrower authority
• obtain an independent inspection
• review the contract
• speak with your solicitor
• notify your broker
• document the issue

The lender may not release a progress payment until the dispute is resolved.

Can the lender refuse a progress payment?

Yes.

The lender may refuse or delay a payment if:

• the stage is not complete
• documents are missing
• inspection fails
• funds to complete are short
• variations are not approved
• insurance is missing
• council approval is missing
• the project is outside the approved scope
• builder invoice does not match the contract

This can create delays with the builder.

Can a renovation loan be declined after valuation?

Yes.

The lender may decline or reduce the loan if the valuation shows:

• completed value is too low
• works are overcapitalised
• property is less marketable than expected
• defects remain
• property will be incomplete
• cost to complete is too high
• saleability is limited

Valuation is often the turning point in renovation finance.

What if the property is uninhabitable during works?

The lender may still approve the loan, but this affects risk and affordability.

If the property is uninhabitable, the lender may consider:

• temporary accommodation cost
• insurance
• construction timeframe
• security value during works
• whether work is fully funded
• when occupancy certificate will be issued
• whether the property can be sold if incomplete

A long uninhabitable period can make the application more complex.

Does insurance need to change during renovations?

Often, yes.

Major renovations can affect insurance.

You may need:

• builder’s construction insurance
• public liability insurance
• contract works insurance
• home warranty or domestic building insurance
• updated building insurance
• lender noted as interested party
• insurance for unoccupied property, if applicable

Standard home insurance may not cover major renovation works unless disclosed.

Can insurance issues stop approval?

Yes.

If required insurance is missing, the lender may not release funds.

Insurance can be especially important where:

• the property is vacant
• roof or walls are removed
• structural works are occurring
• builder is on site
• property is partially complete
• works are high value
• the lender’s security is exposed

Speak with your insurer before work starts.

Does the lender require home warranty insurance?

Usually, where required by law.

For licensed builder works over relevant state thresholds, home warranty, domestic building or indemnity insurance may be required.

The lender may ask for the insurance certificate before approval or progress payments.

Rules vary by state and territory.

Can renovations affect existing home insurance?

Yes.

Your existing home insurer may need to be told before renovations start.

If you do not disclose major works, there may be issues with claims.

The lender may require evidence that the property remains insured during and after construction.

Can strata renovation insurance be different?

Yes.

If renovating an apartment or strata property, insurance can involve both individual and strata policies.

You may need to consider:

• strata building insurance
• contents insurance
• builder insurance
• common property damage
• by-law requirements
• contractors entering common areas
• waterproofing and wet area work

Your solicitor and strata manager should review requirements.

Can council approval problems affect final payment?

Yes.

Final payment may depend on completion evidence such as:

• occupancy certificate
• final inspection certificate
• council sign-off
• building certification
• engineer certification
• practical completion documents

If approvals are incomplete, final drawdown may be delayed.

Can renovation works affect the title?

Usually not, unless subdivision or title changes are involved.

However, some projects may involve:

• strata subdivision
• duplex subdivision
• easements
• boundary changes
• encroachments
• covenant changes
• community title changes

If title changes are involved, lender review becomes more complex.

Can easements affect extensions?

Yes.

An extension may be restricted by:

• drainage easements
• sewer easements
• access easements
• covenants
• building envelopes
• setbacks
• council controls
• neighbour rights

If the proposed extension conflicts with an easement, approvals and valuation can be affected.

Can building covenants affect extensions?

Yes.

Some estates or community title schemes have covenants controlling:

• materials
• façade
• height
• setbacks
• roof form
• fencing
• landscaping
• minimum dwelling size

The lender may not review every covenant, so your solicitor should confirm the extension is permitted.

Can heritage overlays affect extensions?

Yes.

Heritage overlays can add cost, time and design restrictions.

A lender may be concerned if heritage requirements make the project:

• more expensive
• slower
• uncertain
• hard to value
• dependent on specialist trades
• more prone to variations

Heritage projects need strong contingency.

Can bushfire or flood requirements affect renovation finance?

Yes.

Bushfire or flood requirements can increase cost and complexity.

They may affect:

• materials
• engineering
• floor height
• access
• insurance
• council approvals
• valuation
• timeframe

If these requirements are not budgeted, funds to complete may be short.

Can asbestos affect a renovation loan?

Yes.

Asbestos can increase cost and delay works.

Older homes may have asbestos in:

• walls
• eaves
• ceilings
• flooring
• roofing
• wet areas
• sheds
• pipe insulation

If asbestos is likely, obtain appropriate inspections and costings before finance approval.

Can termite damage affect renovation finance?

Yes.

Termite damage can affect structural integrity and cost.

The lender may ask for:

• building report
• pest report
• builder scope
• rectification cost
• valuation comments
• evidence the property will be sound after works

Unexpected termite damage can cause cost overruns.

Can you renovate after buying a property?

Yes.

You may structure finance in different ways:

• purchase first, renovate later from savings
• purchase plus renovation loan
• construction loan from settlement
• equity release after settlement
• staged refinance
• personal loan for minor works

The right option depends on whether the lender relies on the current value or completed value.

Can you buy a property and renovate immediately?

Possibly.

A lender may need to assess both purchase and renovation together if the renovation funds are required at settlement.

They may ask for:

• purchase contract
• renovation contract
• plans
• valuation as if complete
• funds to complete
• LVR
• builder documents
• insurance

This can be more complex than buying first and renovating later.

Can you get one loan for purchase and renovation?

Yes, with some lenders.

A purchase plus renovation loan may combine:

• purchase price
• renovation cost
• stamp duty and costs
• borrower contribution
• completed valuation
• progress payments

The lender needs to be comfortable that the property will be completed and that the borrower has enough funds for both purchase and works.

Can you get renovation finance after settlement?

Yes.

Some borrowers buy the property first, then apply for renovation funds later.

This may be simpler if:

• you build equity
• you save more cash
• you finalise plans
• you obtain approvals
• you choose a builder
• the current value supports the loan

However, if the property needs immediate structural work, waiting may not be practical.

Can renovation finance be approved before settlement?

Possibly.

The lender may approve purchase and renovation together, but it needs enough information.

If plans or contracts are not ready, approval may only cover the purchase.

If renovation funds are essential, do not rely on a purchase-only approval.

Can you renovate a property bought at auction?

Yes, but finance risk is higher.

Auction contracts are usually unconditional.

Before bidding, check:

• purchase loan approval
• renovation finance availability
• valuation risk
• building condition
• cost of works
• council approval requirements
• deposit and funds to complete
• whether the property is habitable

If renovation funds are needed to make the property liveable, check finance before auction.

Can you use a building and pest report for renovation finance?

It can help.

A building and pest report may identify:

• structural defects
• termite damage
• moisture issues
• roof problems
• safety concerns
• unapproved works
• urgent repairs

The lender may not always ask for it, but it can help you budget and avoid underestimating renovation costs.

Can urgent repairs be funded?

Possibly.

Urgent repairs may be funded as:

• cash out
• loan increase
• construction loan
• insurance repair funding
• personal funds

The structure depends on the size and nature of repairs.

If urgent repairs affect habitability or security, the lender may require evidence they will be completed.

Can a renovation loan be used to make a property habitable?

Possibly, but this can be more complex.

If a property is not habitable at purchase, the lender may be cautious.

They may assess:

• current condition
• required repairs
• completed value
• construction contract
• funds to complete
• whether the property is insurable
• whether occupancy certificate is needed
• marketability

Some lenders may not accept an uninhabitable dwelling as standard security until works are completed.

Can you renovate a property with no kitchen or bathroom?

This can be difficult.

A property without a functional kitchen or bathroom may not be considered standard residential security.

The lender may require:

• lower LVR
• construction loan structure
• builder contract
• completion evidence
• valuation after works
• strong funds to complete

If the property is not habitable, lender options reduce.

Can you renovate if the property is currently vacant?

Yes, but insurance and security matter.

The lender may ask whether:

• property is insured while vacant
• works are approved
• site is secured
• utilities are connected
• vandalism risk is managed
• the property will be habitable after works

Vacant properties under renovation can carry higher risk.

Can construction interest be included in the loan?

Sometimes, but not always.

Many borrowers pay interest during the renovation period.

If the loan is progressively drawn, interest is usually charged only on the amount drawn.

Some structures may allow interest capitalisation, but this depends on lender policy and LVR.

Most borrowers should budget to pay interest during the works.

Do repayments increase during a renovation construction loan?

Yes.

As progress payments are drawn, the loan balance increases and repayments usually increase.

If you are also paying rent or another mortgage, cash flow can be tight.

The lender will assess your ability to manage repayments after the full loan is drawn.

What happens after renovation completion?

After the final progress payment, the loan may convert to a standard home loan structure.

This may involve:

• full loan balance drawn
• principal and interest repayments starting or continuing
• interest-only construction period ending
• final valuation or inspection complete
• updated insurance
• normal loan management

The final repayment amount may be higher than the construction period repayments.

What documents are needed for major renovation finance?

Documents may include:

• current loan statement
• title search
• purchase contract, if buying
• builder contract
• fixed-price contract
• plans and specifications
• scope of works
• progress payment schedule
• builder licence
• builder insurance
• home warranty or domestic building insurance
• council approval or building permit
• strata approval, if relevant
• as-if-complete valuation
• quotes for excluded works
• funds-to-complete evidence
• income documents
• bank statements
• credit card and loan statements

The exact documents depend on lender and project type.

What should the renovation contract include?

A strong contract should show:

• builder name and licence
• borrower name
• property address
• fixed price
• scope of works
• inclusions
• exclusions
• progress payment schedule
• start and completion timing
• variation process
• insurance details
• plans and specifications
• signatures

The clearer the contract, the easier the lender assessment.

What should the scope of works include?

The scope of works should clearly describe:

• what is being demolished
• what is being built
• structural changes
• room additions
• kitchen and bathroom works
• roof changes
• external wall changes
• service upgrades
• landscaping or site works
• exclusions
• completion standard

A vague scope can lead to valuation and funding problems.

What should your broker check?

Your broker should check:

• whether the works are cash-out or construction
• which lenders accept the renovation structure
• whether progress payments are required
• maximum LVR
• whether LMI is available
• whether the contract type is acceptable
• whether the lender relies on current or completed value
• whether funds to complete are sufficient
• whether temporary accommodation affects servicing
• whether approvals are required before drawdown

This should be done before you sign contracts or start works.

What should your solicitor check?

Your solicitor or conveyancer should check:

• building contract terms
• finance clauses
• council approval requirements
• strata approvals
• easements and covenants
• heritage restrictions
• builder deposit risk
• variation clauses
• dispute process
• insurance obligations
• what happens if finance is delayed

Legal review is especially important for major renovations.

What should you ask your builder?

Ask your builder:

• Is the contract fixed price?
• What is excluded?
• Are site costs fixed?
• Are provisional sums included?
• What approvals are needed?
• What are the progress stages?
• What happens if hidden defects are found?
• What insurance is included?
• How long will the renovation take?
• Can the home be occupied during works?
• What variations are likely?

Builder answers should be checked against finance and legal advice.

11 common mistakes with renovation construction loans

1. Do not assume all renovation loans are cash out.
2. Do not assume the lender will release all funds upfront.
3. Do not rely on future value without an as-if-complete valuation.
4. Do not underestimate site costs or hidden defects.
5. Do not start major works before finance approval.
6. Do not sign a cost-plus contract without checking lender policy.
7. Do not ignore council or strata approvals.
8. Do not forget temporary accommodation costs.
9. Do not assume variations will be funded.
10. Do not spend contingency too early.
11. Do not assume refinancing halfway through works will be easy.

How to improve your chances of approval

You can improve your chances by making the renovation easy to assess.

Helpful steps include:

• confirm whether works are structural or cosmetic
• use a licensed builder
• obtain a fixed-price contract
• prepare detailed plans and specifications
• obtain council or strata approvals
• get an as-if-complete valuation
• keep a cash buffer
• include site works and essential extras
• minimise provisional sums
• avoid new debts before approval
• keep bank statements clean
• budget for rent or temporary accommodation
• use a lender that accepts renovation construction

The more certainty you provide, the easier the application usually becomes.

Should you wait before applying?

Sometimes waiting can improve your options.

Waiting may help if:

• contract is not fixed price
• scope of works is unclear
• approvals are pending
• site costs are unknown
• valuation cannot be completed
• you need to reduce debts
• cash buffer is too small
• builder insurance is not ready
• you are deciding between cash out and construction loan

You may not need to wait if:

• current equity supports cash out
• renovation is non-structural
• contract is ready
• valuation supports the loan
• funds to complete are clear
• lender policy accepts the project

A broker can compare applying now versus waiting for stronger documentation.

Example scenarios

Scenario 1: Cosmetic renovation funded as cash out

A borrower wants $90,000 for kitchen, bathroom and flooring updates.

The property has enough equity, LVR is within policy and the lender releases funds as cash out without progress payments.

Scenario 2: Structural extension

A borrower wants to add two bedrooms and extend the living area.

The lender treats the project as construction, requires a fixed-price contract, valuation and progress payments.

Scenario 3: Second-storey addition

A borrower wants to add an entire second level.

The lender requires plans, engineering, council approval, builder contract, progress schedule and an as-if-complete valuation.

Scenario 4: Renovation value shortfall

A borrower spends $350,000 on renovations, but the completed valuation only increases by $220,000.

The lender reduces the approved loan amount, and the borrower needs extra cash.

Scenario 5: Owner-managed extension

A borrower wants to coordinate trades themselves.

The lender treats the project as owner-builder and applies lower LVR or declines.

Scenario 6: Renovation after purchase

A borrower buys an older property and wants to renovate immediately.

The lender assesses both purchase and renovation funds together because the borrower needs funds from settlement.

So, can you get a construction loan for major renovations or extensions?

Yes, you can get a construction loan for major renovations or extensions, but the lender will want to understand the scope, cost, value and completion risk.

The strongest applications usually have:

• licensed builder
• fixed-price contract
• clear scope of works
• council or strata approvals
• as-if-complete valuation
• acceptable LVR
• strong funds to complete
• realistic contingency
• progress payment schedule
• current and completed property acceptable as security
• borrower serviceability that allows for construction period costs

Cosmetic renovations may be handled as cash out. Structural renovations and extensions are more likely to need construction lending.
