The short answer: a renovation loan is not a single product. It is any borrowing used to fund home improvements, from a home loan top-up to a construction loan or an unsecured personal loan. The right structure depends on your project size, whether you have equity, and whether the work is structural.
At Noma Finance, we map your renovation to the right lending structure first, then compare across a panel of around 25 lenders, so you see the total cost of the finance before you sign, not just the monthly repayment. For most homeowners, the lowest-cost path runs in this order: your own money first (redraw or offset), then a home loan top-up at home loan rates, a construction loan for structural work, and a personal loan only when you have no equity or the job is small.
A renovation loan is an umbrella term for any finance used to pay for home improvements. Most Australian lenders do not sell a single product called a renovation loan. You are choosing between a top-up, a redraw, refinancing, a construction loan, a personal loan or a green loan.
One fork decides most of it: is the work cosmetic or structural?
A bank can only offer what it sells. A broker compares lenders and maps the structure to your renovation. If you want to see how that comparison differs from walking into your own bank, our guide on using a finance broker versus a bank walks through it.
There are six main ways to finance a home renovation in Australia.
One product is missing on purpose. Credit cards and buy now pay later (BNPL) sit near 20% or higher, so they are for small incidentals only, never a real renovation.
You increase your existing mortgage against the equity you have built. Owe $400,000 on a home worth $700,000, and you could lift the loan to around $560,000 (80% of value) for the works, subject to approval.
Indicative rates sit around 5.7% to 6.9% variable (illustrative only, as at September 2026). The trade-off: a top-up adds to your mortgage, so repayments rise or the term lengthens. Most top-ups are on variable loans, and you usually need to keep your loan-to-value ratio (LVR) at or below 80% to avoid Lenders Mortgage Insurance (LMI).
If you have made extra repayments, you can withdraw them. This is not new borrowing, so there is no new application, and the rate does not change. The catch: not every loan has redraw, and pulling funds out reduces your buffer.
You replace your home loan with a new, larger one. It suits fixed-rate borrowers who cannot top up, or anyone chasing a better rate at the same time. Watch the costs: break fees on fixed loans ($2,000 to $10,000 or more), discharge fees ($150 to $400) and a fresh valuation ($300 to $600), all illustrative. Check the rate savings cover these first.
Required for extensions, second-storey additions, knock-down rebuilds, or any work needing a licensed builder and council approval. Funds are released in stages as the build progresses (slab, frame, lock-up, fixing, completion), and you pay interest only on what is drawn.
You will need a fixed-price building contract, council approval (DA or CDC), detailed plans and builder's insurance. Approval takes four to eight weeks. Budget 10% to 20% contingency on top of the contract sum.
An unsecured personal loan is a lump sum, usually $5,000 to $75,000, repaid over one to seven years. It is the fastest option, with approval in one to three business days and no property valuation. Rates run higher than a top-up, from around 6% for a strong application to 20% or more depending on your situation (illustrative only, as at September 2026).
Monthly repayments are higher than a top-up, but total interest can be lower, because you clear it in years rather than decades. More on that below. If you are weighing a personal loan, our guide to what counts as a good personal loan rate is worth a read first.
If the work includes solar, batteries or insulation, you may qualify for a discounted rate from some lenders. Check whether any part of your project qualifies before you settle on a structure.
Rates are illustrative only, as at September 2026, and depend on your situation.
Most lenders cap borrowing at 80% of your property's current value, minus your existing loan. That is your usable equity.
Borrowing past 80% LVR, and you may trigger LMI (around $5,000 to $15,000 depending on loan size, illustrative). If you are a recent or first-home buyer with little equity, our rundown of first home buyer schemes for 2026 may be a better starting point than a renovation loan.
The lender assesses the property's "as if complete" value. A renovation that adds more value than it costs can expand what you can borrow.
Most lenders cap unsecured loans at $50,000 to $75,000. Some offer up to $100,000 with security.
Whichever path you take, lenders test your repayments at your rate plus the APRA serviceability buffer. As at September 2026, that buffer is 3 percentage points, so a loan advertised at 6% is assessed as though you were paying 9%. The income you need therefore depends on your existing debts, not just the loan size. Two people borrowing the same amount can get different answers based on what they already repay each month. Work out your real position with our budget planner before applying.
This is the part most banks will not show you. Here is an $80,000 renovation across different options.
Figures are illustrative only, as of September 2026, and exclude fees. The 10% personal loan rate reflects a strong application.
The top-up looks lowest at about $515 a month. But over 25 years you pay roughly $74,500 in interest. A personal loan at 10% over five years costs about $1,700 a month, yet total interest is only about $22,000.
The lowest rate does not mean the lowest cost. If you can handle higher repayments, a shorter term can save tens of thousands. If you cannot, a top-up with a deliberate extra-repayment plan (the accelerated row) closes much of the gap. A broker shows you both numbers, so you decide with your eyes open.
Start with the renovation scope, not the loan product.
If your situation does not fit a single row, that is what a broker is for.
Get your renovation quotes first. A clear number makes the application cleaner and shows the lender what the money is for.
A bank shows you one product. A broker compares a panel and maps the lowest-cost structure to your renovation.
At Noma Finance, we start with your scope and budget, check your borrowing capacity and usable equity across lenders, then compare rate, fees, total cost and monthly repayment. You see every number before you sign. In most cases, there is no cost to you, because the lender pays the broker's commission. You can see the full range of what we help with on our services page.
Yes. A personal loan lets you borrow up to around $50,000 to $75,000 without property security. Rates are higher, but approval is fast, and no valuation is needed. For larger projects, a construction loan may assess the "as if complete" value instead.
Home equity offers a lower rate but extends your mortgage. A personal loan costs more per dollar, yet is repaid in five to seven years, so total interest can be comparable on smaller amounts. Compare both the monthly repayment and the total cost.
A bathroom refresh typically runs $10,000 to $25,000, a kitchen remodel $20,000 to $60,000, and a full extension $100,000 or more. Budget an extra 10% to 20% for surprises, and get at least three written quotes.
Home loan top-ups sit around 5.7% to 6.9% variable. Personal loans range from about 6% to 20% or more, depending on your situation. Figures are illustrative only, as of September 2026, and your rate depends on your circumstances and the lender.
Not for the loan, but sometimes for the work. Cosmetic renovations generally do not need council approval. Structural changes need a DA or CDC, and construction lenders may require evidence of approval before releasing funds.
Yes. A broker compares multiple lenders, matches the structure to your renovation scope, and shows the total cost before you sign. In most cases, there is no cost to you, as the lender pays the commission.
Thinking about a renovation and not sure which structure fits? Send through your scope, and we will compare the options across the panel and show you the total cost before you decide. Start your application or get in touch, no pressure either way.
