Home Renovation Loans Australia — Your Finance Options (2026)
Australians spend billions each year on home renovations. Whether you are updating a kitchen, adding a room, or transforming a fixer-upper, there are several ways to finance the work. The best option depends on your equity, the project size, and how quickly you can repay.
Overview of Renovation Finance Options
| Finance type | Secured? | Interest rate (approx.) | Best for |
|---|---|---|---|
| Home loan top-up | Yes (property) | 5.75–6.25% variable | Large projects; strong equity |
| Redraw facility | Yes (existing loan) | 5.75–6.25% variable | Smaller projects; extra repayments available |
| Construction/renovation loan | Yes (property) | 5.75–6.50% | Major structural work |
| Personal loan (unsecured) | No | 8–15% | Smaller projects; limited equity |
| Line of credit (home equity) | Yes (property) | 6.00–7.00% | Flexible ongoing spend; disciplined borrowers |
| Green/energy loan | Sometimes | 5.50–9.00% | Solar, batteries, energy efficiency upgrades |
Option 1 — Home Loan Top-Up (Loan Increase)
The most common way to fund a renovation for existing homeowners with equity.
How it works:
- You request an increase to your current home loan
- The lender re-assesses your income and expenses at the new amount
- Subject to: combined LVR remaining at or below 80% (to avoid LMI), or lender’s maximum LVR
Example:
- Property value: $800,000
- Current loan: $400,000
- Top-up for renovation: $100,000
- New loan balance: $500,000 (62.5% LVR — comfortably below 80%)
Pros:
- Low interest rate (home loan rate)
- Long repayment term reduces monthly impact
- Simple if you already have a home loan
Cons:
- Extends your loan term or increases repayments
- Total interest paid over 20–30 years can be significant
- Requires sufficient equity (typically 20% buffer)
Option 2 — Redraw Facility
If you have made extra repayments on your home loan, you may have funds available to redraw.
How it works:
- Access extra repayments without a new loan application
- Available immediately via internet banking in most cases
- Interest rate: the same as your current loan rate
Pro: Fast access; no new application Con: Only available if you have made extra repayments; reduces your equity buffer
Option 3 — Personal Loan
For borrowers without sufficient equity, or for smaller renovation projects, a personal loan offers quick unsecured finance.
How it works:
- Loan of typically $5,000–$80,000 over 1–7 years
- No property security required
- Fixed or variable rate
Pros:
- No home equity required
- Faster approval than mortgage
- Short term means it is fully repaid relatively quickly
Cons:
- Higher interest rate (8–15%)
- Higher monthly repayments on a 3–5 year term vs 25-year mortgage
- Total interest cost comparable or higher than equity release for large amounts
Quick comparison — $40,000 renovation:
| Finance type | Rate | Term | Monthly repayment | Total interest |
|---|---|---|---|---|
| Home loan top-up | 6.00% | 25 years remaining | $257 | ~$37,100 |
| Personal loan | 10.00% | 5 years | $850 | ~$11,000 |
| Personal loan | 10.00% | 7 years | $664 | ~$15,760 |
The personal loan has a higher monthly repayment but lower total interest. The home loan spread over 25 years has a low monthly payment but significantly more total interest paid.
Option 4 — Construction / Renovation Loan
For major works — extensions, full structural renovations — a construction loan is the appropriate vehicle.
How it works:
- Funds are released in progress payment stages (not upfront)
- You pay interest only on the amounts drawn down
- Requires: fixed-price builder contract, council DA or CDC approval, registered builder
Who uses it:
- Major extensions (adding a bedroom, second storey)
- Knock-down-rebuild on an existing site
- Large-scale structural renovation

Frequently Asked Questions
Can I add renovation costs to my mortgage when purchasing a property?
Some lenders offer “purchase + renovation” loans or construction loans on a newly purchased property. This typically requires quotes and plans at the time of purchase application.
Do I need a fixed-price contract for a renovation top-up?
Not for a standard top-up (where you receive the funds and manage the renovation yourself). However, for a formal construction loan with progress drawdowns, a fixed-price contract with a licensed builder is required.
Does a renovation need to add value to qualify for a home loan top-up?
Lenders assess the security value (current property value) — not the expected post-renovation value. Some specialist lenders may take a post-renovation valuation into account, but this is not standard.
