A home renovation loan is any form of finance used to fund improvements, extensions, or upgrades to your property. Unlike a standard home loan used to purchase a property, renovation finance is specifically structured to fund the cost of building works on an existing home.
Whether you are planning a kitchen makeover, bathroom upgrade, home extension, outdoor living area, or a complete knockdown-rebuild, there are several finance options available. The right choice depends on the scale of your renovation, the equity available in your property, your borrowing capacity, and your personal financial situation.
With property prices in Geelong, the Surf Coast, and Melbourne continuing to grow, many homeowners are choosing to renovate their existing property rather than sell and buy a larger home. Renovating can avoid the significant costs of selling (agent fees, marketing, legal costs) and buying (stamp duty, conveyancing, moving costs), which can easily total $50,000 to $100,000 or more on a mid-range property.
There are several ways to finance a home renovation in Australia. Each option has different advantages, costs, and suitability depending on your circumstances.
Home loan top-up or increase: If you have sufficient equity in your property, you can increase your existing home loan to fund the renovation. This is often the most cost-effective option as you benefit from home loan interest rates (typically 5.5% to 7%) rather than higher personal loan rates. The additional amount is added to your existing loan with the same terms and repayment structure.
Construction loan: For major renovations or extensions, a construction loan provides staged drawdowns as the work progresses. The builder submits progress claims at agreed milestones (such as slab, frame, lock-up, fit-out, completion), and funds are released after inspection. You only pay interest on the amount drawn, which keeps costs lower during the construction phase. This is the best option for renovations exceeding $100,000.
Line of credit: A line of credit secured against your home equity provides flexible access to funds. You can draw down as needed, repay, and redraw without reapplying. This works well for renovations completed in stages or where the exact budget is not yet finalised. Interest is charged only on the drawn balance.
Personal loan: For smaller renovations under $50,000, a personal loan may be appropriate. Personal loans are unsecured, meaning you do not need to use your property as collateral, and approval is usually faster. However, interest rates are significantly higher (typically 7% to 15%) and loan terms are shorter (usually 3 to 7 years), resulting in higher monthly repayments.
Refinancing to a new lender: If you are planning a major renovation, it may be worth refinancing your entire home loan to a new lender who offers a better rate and including the renovation costs in the new loan amount. This can save you money on both the existing loan and the renovation finance component.
| Finance Option | Best For | Interest Rate | Loan Term |
|---|---|---|---|
| Home Loan Top-Up | Any size with available equity | 5.5-7% | Up to 30 years |
| Construction Loan | Major renos over $100K | 5.5-7% | 12-24 months (then converts) |
| Line of Credit | Staged or flexible renos | 6-8% | Revolving |
| Personal Loan | Small renos under $50K | 7-15% | 3-7 years |
| Refinance + Reno | Large renos + rate improvement | 5.5-7% | Up to 30 years |
Not all renovations add equal value to your property. Understanding which improvements deliver the best return on investment helps you make smarter decisions about where to allocate your renovation budget.
Kitchen renovation: The kitchen is one of the first things buyers look at. A well-executed kitchen renovation can recoup 50% to 80% of the investment in added property value. Focus on quality bench tops, modern appliances, good storage, and a functional layout. Budget renovations ($15,000 to $30,000) can still deliver excellent results if you update the most impactful elements.
Bathroom upgrade: Bathrooms are the second most scrutinised room by buyers. A dated bathroom can significantly reduce a property’s appeal. Modern tiling, good fixtures, frameless shower screens, and adequate lighting can transform a bathroom for $10,000 to $30,000. Adding an ensuite to the main bedroom is particularly valuable if the property does not currently have one.
Additional bedroom or living space: Adding a bedroom or extending living areas increases both the functional space and the property’s market value. Converting a garage, adding a granny flat, or extending the rear of the home are popular options. The value added depends heavily on the local market. Check what comparable properties with extra bedrooms are selling for in your area.
Outdoor living areas: In the Australian climate, well-designed outdoor entertaining areas are highly desirable. A covered deck, alfresco area, or outdoor kitchen can add significant appeal and value, particularly in areas like the Surf Coast and Geelong where outdoor living is a key part of the lifestyle.
James and Kate owned a 1970s three-bedroom home in Belmont valued at $580,000. Rather than selling and buying a larger home (which would have cost them approximately $65,000 in transaction costs), they decided to renovate. We helped them access $150,000 through a home loan top-up secured against their equity. They completed a new kitchen ($35,000), two bathroom renovations ($25,000), a rear extension adding a fourth bedroom and open-plan living area ($75,000), and landscaping ($15,000). After completion, the property was revalued at $790,000, an increase of $210,000 for a $150,000 investment, representing a net gain of $60,000 plus the $65,000 saved on transaction costs.
The application process for renovation finance depends on the type of finance you choose and the scale of the renovation. Here is what to expect for each approach.
For a home loan top-up: Contact your broker to assess your current equity position and borrowing capacity. You will need a recent valuation of your property, detailed renovation plans or scope of works, builder quotes for the proposed work, and evidence that the renovation will be completed within a reasonable timeframe. Your lender will assess whether the post-renovation value supports the increased loan amount.
For a construction loan: The process is similar to a new construction loan. You will need approved building plans, a fixed-price building contract with a licensed builder, council-approved permits, a quantity surveyor report (for larger projects), and evidence of your equity contribution. Funds are released in stages as the builder completes each phase of the renovation.
Get your finance approved before signing any building contracts. This protects you from committing to renovation costs before you know how much you can borrow. Your broker can arrange a pre-approval based on the proposed renovation scope, giving you confidence to proceed with builder negotiations.
Using credit cards or personal loans for large renovations: Funding a $50,000+ renovation on credit cards or high-interest personal loans can cost you tens of thousands of dollars in additional interest compared to using home equity. Even factoring in the longer repayment term, home loan interest rates are significantly cheaper.
Overcapitalising: Spending more on renovations than the value they add to the property is a common mistake. Research comparable property values in your area before planning your renovation to ensure the total cost (property value plus renovation) does not exceed the maximum value achievable for homes in your street and suburb. Your broker or a local real estate agent can provide guidance on the price ceiling for your area.
Not budgeting for contingencies: Renovation projects almost always encounter unexpected costs: hidden structural issues, asbestos, plumbing or electrical problems, or design changes. Budget an additional 10% to 20% above your expected costs as a contingency buffer. If you do not use it, you can put it toward the mortgage. But having it available prevents a funding shortfall mid-project.
Starting without proper approvals: Beginning renovation work before obtaining the necessary council permits and building approvals can result in stop-work orders, fines, and the requirement to undo completed work. It can also create problems with your lender, who may withhold funding until proper approvals are in place. Always obtain all necessary permits before construction begins.
Not getting multiple quotes: Obtaining at least three quotes from licensed builders ensures you are paying a fair price and gives you leverage in negotiations. Be wary of quotes that are significantly lower than others, as this may indicate the builder has underestimated the scope or plans to cut corners. A good builder at a fair price is more valuable than the cheapest option.
A well-planned renovation budget is essential for both the success of your project and the approval of your finance application. Lenders want to see that you have thoroughly considered all costs and have a realistic plan for completing the work within budget.
Start by identifying the scope of work and obtaining detailed quotes from at least three licensed builders. Your budget should include the building contract amount, council fees and permit costs, architectural and engineering fees, fixtures and fittings allowances, landscaping costs, temporary accommodation if needed, and a contingency of 10% to 20%. For a typical mid-range renovation in the Geelong area, expect to pay approximately $2,000 to $3,500 per square metre for extensions, $20,000 to $50,000 for a kitchen renovation, and $15,000 to $30,000 per bathroom.
It is also important to consider the timeline. Renovations commonly take longer than expected, and delays can affect your finance costs if you are paying interest during the construction period. A realistic timeline helps you budget accurately for interest charges and any temporary living arrangements.
Renovating an investment property has additional financial considerations compared to renovating your own home. The potential benefits include increased rental income, improved capital value, and tax deductions for the renovation costs.
Tax deductions: Renovation costs on an investment property can be claimed as tax deductions. Capital works (structural improvements, additions) can be depreciated at 2.5% per year over 40 years. Plant and equipment items (carpet, blinds, appliances, hot water systems) can be depreciated at their individual effective life rates. Repairs to restore something to its original condition (as opposed to improvements) may be fully deductible in the year incurred.
Rental yield impact: A well-executed renovation can significantly increase your rental income. Updating a tired three-bedroom house in Geelong from $380 per week to $480 per week represents a $5,200 annual increase in rental income. Over 10 years, that is an additional $52,000 in rent, which can easily justify a $30,000 to $40,000 renovation investment.
Financing considerations: Investment property renovations are financed in the same way as owner-occupied renovations, but the interest on the loan is tax deductible. This makes the effective cost of borrowing lower for investment renovations compared to owner-occupied renovations, potentially making a home equity draw even more financially attractive.
A mortgage broker adds significant value when arranging renovation finance. They can assess your current equity position and borrowing capacity, compare finance options across multiple lenders to find the best structure and rate, advise on the most tax-effective finance structure (particularly for investment renovations), coordinate the application process including valuations and documentation, and manage the drawdown process for construction loans.

To access home equity for a renovation, your total borrowing (existing loan plus renovation amount) generally cannot exceed 80% of the property’s current value without LMI. For example, if your home is worth $700,000 and you owe $400,000, you have $160,000 in usable equity (80% of $700,000 = $560,000, minus your $400,000 loan). Some lenders allow up to 90% LVR with LMI if you need more.
Most lenders are reluctant to fund owner-builder renovations due to the increased risk of cost overruns, delays, and quality issues. If you plan to be an owner-builder, your options are more limited and you may need to use a personal loan, line of credit, or savings rather than a construction loan. Some lenders will consider owner-builder finance if you can demonstrate relevant trade qualifications or experience.
This depends on the type of renovation, quality of work, and local market conditions. Generally, well-planned renovations that address functional deficiencies (outdated kitchen, insufficient bedrooms, lack of living space) recoup 50% to 80% of their cost in added value. Cosmetic upgrades (paint, carpet, landscaping) often deliver the highest percentage return due to their lower cost. Always research comparable sales in your area to understand the potential value uplift.
For minor renovations (bathroom upgrade, kitchen makeover), you can usually continue living in the property with some inconvenience. For major renovations or extensions, it may be necessary to move out temporarily. If you need to rent during the renovation, factor this cost into your overall budget. Your lender does not typically require you to vacate, but your builder may request it for safety or efficiency reasons during certain construction phases.
