Refinancing To Renovate in Perth, WA, Your Practical Guide
You've built equity in your home and you'd like to put it to work, but you're not sure whether the bank will treat a renovation the same way it treats a standard refinance. The short answer is: sometimes yes, sometimes no, and the structure you choose matters as much as the equity itself.
Refinancing to renovate is one of the more flexible strategies available to Perth homeowners, and it's also one of the more misunderstood ones. Whether you're adding a second storey, updating a kitchen, or converting the garage, the lending path depends on what you're spending, how much equity you've got, and what the property will be worth once the work is done.
Our team helps homeowners across Perth, WA work through the refinancing side of a renovation project, comparing across 60+ lenders to find the structure that suits the scope of work and your longer-term position.
Key takeaways
- Most lenders cap equity release at 80% LVR of the post-renovation value.
- The lender values the property now, not after the work is finished.
- Construction loans and equity release are different paths for the same goal.
Can you use your home equity to fund a renovation in Perth, WA?
Yes, and it's one of the most common reasons Perth homeowners refinance. If your property has grown in value since you bought it, you may be able to access a portion of that equity to fund building work, without touching your savings or taking out a personal loan. The approach works best where the renovation adds genuine value to the property, which most structural and cosmetic improvements do in the Perth market.
How does refinancing to renovate actually work?
When you refinance to renovate, you're increasing your loan balance to release equity that has built up in the property. The lender assesses your current property value, calculates how much you can borrow against it at a safe loan-to-value ratio, and the difference between what you currently owe and that new limit is what becomes available for the renovation. Most lenders set that limit at 80% LVR, which avoids lenders mortgage insurance and keeps the structure clean.
There are two main paths for accessing funds, and they suit different scopes of work.
The options worth weighing:
- › Equity release via refinance: suits cosmetic or mid-scale renovations · funds released as a lump sum or line of credit · assessed on current property value · simpler process than a construction loan
- › Construction loan: suits major structural work or new builds · funds drawn in stages as work progresses · interest charged only on drawn amounts · lender inspects at each stage before releasing funds
- › Cash-out refinance to a new lender: combines a competitive rate with equity release · assessed at 80% LVR on current value · suits borrowers whose existing lender won't approve the release
"We regularly see borrowers who go straight to their existing lender for a renovation top-up, get knocked back, and assume they can't access the equity at all. A lot of the time they can, through a different lender, on a structure the current one doesn't offer."

What do you need to qualify to refinance for a renovation?
The eligibility test for a renovation refinance is the same as any refinance: you need enough equity, enough income to service the new, higher loan amount, and a credit position that the new lender is comfortable with. The renovation itself adds a layer on top of that.
What lenders look at:
- › Current equity position: most lenders release funds to a maximum of 80% LVR against the current valuation. The gap between what you owe and that ceiling is your accessible equity.
- › Serviceability on the new balance: your income is assessed against the increased loan amount plus the APRA buffer of 3.0 percentage points above the actual rate. The renovation spend becomes part of the loan, not a separate commitment.
- › Scope of work: a cosmetic refresh rarely needs more than a standard equity release. Major structural changes, extensions or a second storey typically push a lender toward a construction loan structure, which has its own approval process.
- › Council approval status: lenders want to see building permits and, where required, development approval before releasing funds for structural work. An unapproved extension is a valuation risk.
- › Licensed builder requirement: for a construction loan draw-down structure, a fixed-price contract with a licensed builder and council-approved plans are standard requirements before the first draw.

What does it cost to refinance for a renovation in Perth, WA?
The costs of refinancing to renovate sit in two buckets: the costs of the refinance itself, and the cost of the renovation funds once released. On the refinance side, you're looking at discharge fees from your existing lender, a new loan application or establishment fee, and a lender valuation of the property. None of those figures are standardised across lenders, which is one reason comparing across a panel matters.
The valuation is the one cost that catches people off guard. The lender values the property as it stands today, not as it will look after the renovation is finished. On a $1.2 million property in Bayswater, Morley or Cannington, that distinction sets the ceiling on what you can access before the work begins. REIWA data shows Bayswater's median house price at $1,201,000 and Cannington's at $800,000, with 12-month growth of 17.7% and 26.2% respectively, meaning equity positions have moved materially in both suburbs over the past year.
If your renovation will meaningfully lift the property's value, some lenders will allow a revaluation after completion and release additional equity at that point. Not all will, and the willingness to do so varies by lender, which is worth knowing before you commit to a structure.

How long does it take to refinance for a renovation?
A standard equity-release refinance typically takes two to four weeks from application to settlement, assuming the valuation comes back as expected and the documentation is clean. A construction loan structure takes longer, because the lender needs to assess the building contract and plans before issuing formal approval, and that assessment adds one to two weeks at minimum.
What delays things most is incomplete documentation at the start: missing council approvals, a building contract that isn't fixed-price, or a valuation that comes in below expectations. Getting those in order before you apply is the single biggest time-saver in this process.
When does refinancing to renovate not make sense?
It doesn't suit every situation, and being clear about that upfront saves a frustrating application. If your current equity position sits above 80% LVR already, most lenders won't release additional funds without LMI, which adds to the renovation budget in a way that often doesn't stack up financially.
It also doesn't suit renovations where the scope is genuinely uncertain. A fixed-price contract with a licensed builder is a lender requirement on construction structures, and a cost-plus arrangement or owner-builder approach narrows the panel significantly. If you're planning to manage the build yourself, the number of lenders willing to participate drops sharply, and the terms reflect that.
Where the renovation spend is modest and the equity position is strong, a personal loan or a line of credit attached to the existing loan may actually be a simpler structure than a full refinance. Running the numbers on both before committing to one is worth the conversation.
"Where a borrower has a solid equity position but a variable income, I'd usually suggest getting the valuation done and the structure confirmed before they sign a building contract. The worst outcome is a signed contract and a lender that won't release the funds to pay it."

How to refinance to renovate in Perth, WA, step by step
Most of the complexity in this process sits at the beginning, not the end. Getting the structure right before the builder is engaged saves time and avoids the risk of a signed contract with no confirmed funding.
Step 1: Talk to us
We start by mapping your current equity position, the likely valuation, and which structure suits the renovation scope and your income position.
Step 2: Get a valuation and confirm the accessible equity
We order a lender valuation on the current property, confirm what the 80% LVR ceiling looks like against what you owe, and identify the realistic release amount before you commit to a build budget.
Step 3: Match the right lender and structure, then apply
We match the scope of work, the loan structure, and your financial position to the lenders on our panel most likely to approve it, then prepare and submit the application with full documentation.
Step 4: Manage approval through to fund release
We handle the lender's conditions, coordinate the valuation and any building contract review, and make sure funds are available when the builder needs them.
What goes wrong when people refinance to renovate?
Where borrowers lose ground:
- › Signing the building contract first: the most common and most costly mistake. A lender's valuation and credit assessment can take two to three weeks. Signing a fixed-price contract before funding is confirmed puts you in a difficult position if the release amount falls short.
- › Underestimating the serviceability test: the new loan balance is assessed at the actual rate plus the 3.0% APRA buffer. Borrowers who model repayments at the current rate, not the assessment rate, can be surprised by a lower approval than expected.
- › Assuming the renovation lifts the valuation immediately: the lender values the property as it stands on the day of assessment. The post-renovation lift is real but it doesn't count until the work is complete and a fresh valuation is ordered.
- › Going to only one lender: construction loan policies, equity release limits and the willingness to approve a revaluation post-completion vary significantly across lenders. A lender that says no on one structure may say yes on another, which is where comparing across a panel finds the difference.
Frequently Asked Questions
Can I refinance to renovate if I'm already close to 80% LVR?
You can, but the amount available will be limited or require LMI. Most lenders release funds to 80% LVR without LMI, and beyond that the cost of insurance often outweighs the benefit of accessing extra equity for a renovation.
Does the lender need to approve what the renovation money is spent on?
For a standard equity release, lenders rarely dictate how funds are used once released. For a construction loan draw-down, funds are released in stages against the building contract and inspected at each draw, so the spend is directly tied to the approved scope of work.
What if my renovation is owner-built or cost-plus, not fixed-price?
The lender panel for owner-builder and cost-plus arrangements is significantly narrower than for a fixed-price licensed builder contract. Most mainstream lenders won't touch it, and the specialist lenders that will tend to work at lower LVRs and higher rates.
Is refinancing to renovate better than a personal loan for home improvements?
For larger renovations, a home loan rate is substantially lower than a personal loan rate, so refinancing is usually the better structure where the equity is there. For smaller cosmetic work under around $30,000, the cost of a full refinance may outweigh the rate saving, which is worth modelling before committing.
Can I refinance to renovate and then sell shortly after?
Yes, there are no restrictions on selling after a renovation refinance. If you're on a fixed rate with the new lender, check the break cost before setting a sale timeline, as those fees can be material depending on how rates have moved.
Should I use a mortgage broker or go directly to a lender for a renovation refinance?
A mortgage broker, every time. Construction loan structures and equity release policies differ significantly between lenders, and the lender most likely to approve your specific renovation scope and income profile is rarely obvious from the outside. Comparing across a panel finds that match; a single application to one lender does not.
Your Next Steps
Refinancing to renovate in Perth, WA works best when the structure is confirmed before the builder is engaged. The equity position, the valuation, and the lender's appetite for the renovation type all need to align, and those variables differ enough between lenders that the panel choice often determines whether the project is fundable at all.
The right lender for a renovation refinance depends on your situation, and that's a conversation worth having. Talk to the Launch Finance team or call 08 9367 4222, and we'll compare your options across 60+ lenders.
