Equity is a word that gets used constantly and explained rarely. It's the difference between what your property is worth today and what you still owe on it.
If your home is worth $900,000 and you owe $300,000, your equity is $600,000. The amount you could actually borrow against is considerably smaller. Example is indicative only.
Your equity grows in two ways, as you pay down the loan and as the property's value changes. Whether you're thinking about renovating, upgrading, buying an investment or simply want to know where you stand, understanding it is a sensible starting point.
Usable Equity Is Not All Your Equity
Equity is often discussed as a single figure, but not all of it is accessible. As a general rule, lenders will allow you to borrow up to 80% of a property's value, less whatever you still owe. That's what gets called usable equity.
On the example above, 80% of $900,000 is $720,000. Take off the $300,000 owing and roughly $420,000 is potentially usable, rather than the full $600,000. Borrowing above 80% of the property's value may trigger Lenders Mortgage Insurance, which adds to the cost of the loan. These figures are indicative only and lender policy varies.
What People Actually Use Equity For
For a lot of homeowners equity is more than a number on paper. Depending on circumstances it can fund home improvements such as a kitchen, bathroom or outdoor area. It's also commonly used to help purchase an investment property, invest in shares, cover education costs or finance a major purchase.
Some homeowners use equity to consolidate other debts, increasing the home loan to repay higher-interest credit cards or personal loans and leaving a single repayment to manage. That can work, though it isn't right for everyone. Rolling a short-term debt into a 30-year loan lowers the monthly figure while increasing the total interest paid, so it deserves a careful look rather than a quick yes.
The Four Common Ways To Access It
- Top-up loan. You increase your existing home loan and take the additional funds as a lump sum for an approved purpose.
- Separate loan split. Rather than increasing the current loan, you establish a separate account secured against the property. Useful for keeping borrowings for different purposes clearly apart.
- Refinancing. You replace the existing loan with a new one, which can release funds while also giving you a reason to review the rate, features and structure. Our explainer on what actually happens when you refinance walks through the process.
- Line of credit. You draw on an approved limit as you need it rather than taking a lump sum, and generally pay interest only on what you've used.
What To Weigh Before You Draw On It
Using equity generally increases both your total debt and your regular repayments, so the first question is what it does to your budget. Rates may change over time, which affects future repayments. And because the property is the security for the loan, failing to meet repayments puts the home itself at risk.
The right approach depends on what you're trying to achieve and what your borrowing capacity allows. If you're holding surplus cash alongside a plan to access equity, our comparison of offset and redraw is worth reading, because the structure you choose changes how hard that money works.
What The Downturn Does To Your Position
Property values and equity are tied together. When values rise, equity builds faster. When they fall, the amount available shrinks, and that lands unevenly.
Someone who has owned for several years and paid down the loan steadily may still have substantial usable equity even after the recent falls, which we tracked in this month's market update. Recent buyers who entered with smaller deposits are more exposed. In some cases falling values lead to negative equity, where the property is worth less than the outstanding balance. Knowing which of those describes you is the point of checking before you plan around it.
Where To Start
A review will tell you the current market value, roughly how much equity is usable and whether accessing it suits what you're trying to do. Your lender will want its own valuation before anything proceeds. If you're deciding who to work through, the strategy hub on things to ask a broker in 2026 is a useful companion.
