Home Renovation Finance Australia — Your Options Guide
Financing a home renovation in Australia depends on the scale of the project, your equity, and whether the work requires council approval or construction-phase drawdowns. This hub covers every major renovation finance pathway.
Renovation Finance at a Glance
| Project type | Finance option | LVR limit | Key consideration |
|---|---|---|---|
| Cosmetic (paint, flooring, kitchen bench) | Personal loan or savings | N/A | No lender involvement needed if self-funded |
| Mid-range (bathroom, kitchen refit, decking) | Top-up home loan or personal loan | Up to 80–90% | Use equity if available |
| Major structural or extension | Construction/renovation loan | Up to 80% | Progress drawdowns aligned to build stages |

How Much Equity Do You Need?
If you own a home, equity is the difference between the property’s value and your outstanding loan balance. Most lenders allow you to access equity up to 80% of the property’s value without paying LMI.
$$\text{Usable equity} = (\text{Property value} \times 80%) - \text{Loan balance}$$
Example: Property worth $850,000; loan balance $520,000 $$($850{,}000 \times 0.80) - $520{,}000 = $680{,}000 - $520{,}000 = $160{,}000$$
You can access up to $160,000 to fund a renovation without LMI.
Renovation Finance Options
1. Home Loan Top-Up (Equity Release)
- Increase your existing loan balance using built-up equity
- Interest rate: same as your current home loan (~5.75–6.25% variable)
- Repayments: principal and interest over remaining loan term
- Best for: larger renovations where equity is available
2. Redraw from Offset/Redraw Facility
- Access extra repayments already made on the loan
- Available immediately (no new application in most cases)
- Interest rate: home loan rate
- Best for: quick access to modest renovation funds if excess repayments exist
3. Personal Loan
- Unsecured; no property equity required
- Interest rates: typically 8–15% (higher than home loan)
- Terms: 1–7 years
- Best for: smaller projects where equity is unavailable or the borrower is in early repayment phase
4. Construction / Renovation Loan
- Funds released in stages (progress payments) as work is completed
- Interest only on funds drawn down (not the full approved amount)
- Requires fixed-price building contract and council approval
- Best for: major extensions, structural renovations, new additions
5. Line of Credit
- Flexible access to funds up to an approved limit
- Interest charged on balance outstanding
- Higher risk: ongoing interest accumulation without a structured repayment plan
- Less common than they once were; lenders have tightened access

Key Considerations Before Borrowing
Council approval: Structural work, extensions, and any additions that change the building envelope typically require Development Application (DA) or Complying Development Certificate (CDC) approval. Costs $500–$5,000+ depending on council and project.
Fixed-price contract: For construction loans, lenders require a fixed-price building contract. This protects you and the lender from cost overruns — though variations can increase costs during construction.
Contingency: Always budget 10–20% above the quoted cost. Hidden structural issues, rising materials costs, and variations are extremely common.
Loan term: Rolling renovation costs into a home loan means you may repay them over 20–30 years — at low interest, but over a very long period. Calculate total interest cost vs a shorter personal loan term.
Frequently Asked Questions
Can I borrow more than the renovation costs?
Lenders will fund only up to the approved project cost (or the security value, whichever is lower). You cannot borrow excess beyond the renovation amount and use it for other purposes.
Does a renovation increase my home’s value enough to cover the cost?
It depends on the project. Kitchens and bathrooms typically return 50–80% of cost in value increase. Extensions and pools vary widely depending on location, quality, and market conditions. Overcapitalising (spending more than the market will pay) is a real risk — particularly in lower-value areas.
Is renovation loan interest tax-deductible?
If the property is used for investment purposes, the interest may be deductible. For owner-occupied renovations, interest is not deductible. Speak with a tax adviser for your specific situation.
