How to Use Your Home Equity to Pay Off Your Mortgage Sooner

Australian homeowners have seen remarkable growth in property values over the past 5 to 10 years. According to CoreLogic data, median dwelling values in major cities like Sydney and Melbourne have risen approximately 50% to 70% since 2015 - even allowing for the recent cooling some markets have seen.

This growth has created significant equity for many homeowners, often amounting to hundreds of thousands of dollars. For homeowners who own outright or have a small mortgage relative to their property's value, that equity is more than a number on paper - it can be a financial tool to accelerate mortgage repayment, build a property portfolio, and create longer-term wealth.

The strategy: use the equity in your existing home to invest in property, then use the income and growth from that investment to pay your home loan off sooner.

Why home equity matters more than ever

The equity built up in your home represents purchasing power most homeowners never fully use. Depending on your lender's policies and your financial situation, you may be able to access this equity through a line of credit or a home equity loan - and use it to fund the deposit on an investment property without needing to draw from your savings.

For many homeowners, this is the difference between never owning an investment property and getting their first one in motion. Simply making extra repayments on your home loan isn't always the most effective way to reduce your mortgage term. A well-chosen investment property may generate capital growth and potential tax benefits that can be applied toward paying down your home loan faster.

The key phrase is "well-chosen." A poorly selected investment can lead to ongoing losses and financial strain. So before getting into how the strategy works, let's talk about getting the property right.

How to select the right property to accelerate your mortgage payoff

1. Focus on growth corridors

Look at suburbs or regions with strong infrastructure projects, population growth, and employment opportunities. Areas undergoing development or gentrification often offer better capital growth over time. Brisbane's South-East corridor, parts of Adelaide, and selected outer growth zones around Sydney are all examples of where current data suggests strong fundamentals.

2. Consider property type and condition

Newer properties or well-maintained homes tend to attract reliable tenants and reduce unexpected maintenance costs. Units or townhouses in popular locations can offer good entry points for first-time investors - typically lower entry prices and easier to manage.

3. Research market trends and seek expert advice

Use data from credible sources - the Australian Bureau of Statistics, CoreLogic, PropTrack - to inform your choices. For specific markets you don't know well, a buyers agent in that area can be invaluable. We can help you find the right professionals to work alongside.

Using investment property to pay off your home sooner

Once you own an investment property, you may be able to use the rental income and tax benefits to make additional repayments on your home loan.

Tax deductions from investment property expenses - loan interest, depreciation, property management fees, council rates - can improve your overall cash flow position. Over time, capital growth on the investment property may provide a substantial gain when you sell, which can then be used to pay down your home mortgage in a single lump sum.

Here's a simplified example. A homeowner purchased an investment property in a Brisbane growth suburb several years ago by leveraging the equity in their primary home. Capital growth of around 40% combined with rising rental income allowed them to make consistent extra repayments on their home loan. As a result, they may be on track to reduce their mortgage term by several years and improve their overall financial position.

Individual results will vary depending on property performance, location, supply and demand, financing arrangements, and tax circumstances. This is general information - your specific situation needs to be modelled by your accountant and broker before any decisions are made.

Benefits beyond faster mortgage repayment

Using equity strategically opens up benefits beyond just paying off your home sooner. You can build a property portfolio - accumulating assets that can fund or part-fund your retirement or other financial goals. You gain diversification - owning multiple properties spreads your risk and income sources. You may improve tax efficiency - strategic use of deductions and depreciation can support your cash flow. And you build financial security - paying off your home sooner reduces interest costs and increases your equity buffer for future opportunities.

Risks and things to keep in mind

Investing in property is not without risks. Market fluctuations, unexpected vacancies, and maintenance expenses can impact returns. You may need to cover shortfalls from other income sources, so maintaining a financial buffer is essential.

Equity-based investing also increases your total debt and the security tied to your home. If markets fall significantly, you could end up in a position where the investment property is worth less than the equity you accessed. Plan for a longer horizon - typically seven years or more - rather than expecting quick gains.

Always seek professional advice to ensure your property investment strategy aligns with your long-term goals, risk tolerance, and broader financial picture.

Where to start

If you're considering leveraging your home equity to invest in property, the order of operations typically looks like this. First, an equity assessment - your broker reviews your current home value, outstanding loan balance, and lender policies to determine how much equity you can access. Then a borrowing capacity check - separate from the equity question, the lender confirms you can service both loans on your income. Pre-approval gives you certainty before you start looking at properties. Then comes property research, with the buyers agent or property expert of your choice. Finally, purchase and structure - settling on the property with the right loan structure (often investment loans with offset accounts work best).

The first conversation costs nothing and gives you a clear picture of what's actually possible for your situation.
