How to Use Your Home Equity to Build Wealth — The Complete Australian Guide

If you own a home in Australia, you're almost certainly sitting on equity you haven't used. And if you've owned for more than a few years in any major city, that equity is likely substantial.

This guide explains how equity works as a credit concept — how lenders calculate it, the common ways it can be accessed, and the structural considerations involved. It is general information only. Decisions about whether and how to use equity are personal, and where investment products are involved, advice should be sought from an appropriately licensed financial adviser.

What Is Home Equity?

Equity is the difference between what your property is worth and what you owe on your mortgage. If your home is worth $1.2 million and you owe $520,000, you have $680,000 in total equity.

But total equity and usable equity are different things. Most lenders will allow you to access equity up to 80% of your property's value without paying Lenders Mortgage Insurance (LMI). So your usable equity is:

(Property Value × 80%) − Remaining Loan Balance = Usable Equity

Using our example: ($1,200,000 × 80%) − $520,000 = $440,000 in usable equity.

That's an indicative $440,000 in usable equity that could potentially be accessed, subject to serviceability and lender criteria.

How Has Your Equity Grown?

If you bought a property in Sydney five years ago, your equity has likely grown from two sources: your loan repayments (which reduce your outstanding balance) and capital growth (which increases your property's value).

The combination of these two forces is powerful. A property purchased for $1 million five years ago with a $200,000 deposit and $800,000 loan might now be worth $1.4 million with a loan balance of $720,000 — giving usable equity of $400,000 compared to the original $200,000 deposit.

How to Access Your Equity

There are three main ways to access equity: refinancing, a line of credit, and a redraw facility.

Refinancing is the most common approach for equity release. You refinance your existing loan to a new lender (or stay with the same lender) and increase the loan amount to access the equity. The additional funds can be drawn as cash or used directly for an investment purchase.

A line of credit (or equity loan) creates a separate facility secured against your property that you can draw on as needed — similar to a credit card but secured by property and at a much lower interest rate.

A redraw facility allows you to access money you've previously paid above your minimum repayment. This is the simplest form of equity access but has important tax implications for investors.

The Tax Implications — Why Structure Matters

This is where many Australians make costly mistakes. The tax deductibility of interest on an equity loan depends entirely on what you use the funds for. If you use the equity to buy an investment property or shares, the interest is potentially deductible. If you use it for personal expenses, it's not.

The key is keeping investment debt completely separate from personal debt — with separate accounts, separate loan facilities and clear documentation of the purpose of each drawdown. Getting this wrong — even accidentally — can contaminate your deductibility claims and cost you significantly over time.

This is precisely why the loan structuring side of any equity strategy is so important — and where a broker can add genuine value through clean lending setup.

What to Do With Your Equity

Once you've accessed your equity correctly, the question is where to deploy it. The two most common strategies for Australian property owners are investment property and share/ETF portfolios.

Investment property using equity as a deposit is the classic wealth-building strategy. Your equity funds the deposit on an investment property, which generates rental income, benefits from depreciation deductions and (ideally) grows in value over time. The mortgage interest on the investment loan is deductible, and the property's growth compounds alongside your owner-occupied property.

ETF portfolios are an increasingly popular alternative or complement to investment property. Using equity to fund a diversified ETF portfolio gives you exposure to market returns without the concentration risk of a single property, no stamp duty, lower transaction costs and the ability to invest smaller amounts over time. Interest on funds borrowed to invest in shares is also potentially deductible, subject to your accountant's advice.

Many of our clients do both — a combination of investment property and ETF portfolio that diversifies their wealth across asset classes.
