Home Equity in Australia: How to Access and Use It

Home equity is the difference between your property's current market value and what you still owe on your mortgage. As you pay down your loan and as property values rise, your equity builds — creating a potential source of finance for renovations, investment, or emergencies. Most Australian lenders allow you to access equity up to 80% of your property's value without requiring Lender's Mortgage Insurance (LMI).

Usable Equity Formula

Usable equity = (Property value × 80%) − Outstanding mortgage. For example, a $850,000 property with a $420,000 mortgage: usable equity = ($850,000 × 0.80) − $420,000 = $680,000 − $420,000 = $260,000. You could access up to $260,000 through a home equity loan or line of credit.

Frequently Asked Questions

How do I calculate my home equity in Australia?
Total equity = Current property value − Outstanding mortgage balance. Usable equity (without LMI) = (Property value × 80%) − Outstanding mortgage. Most banks will lend up to 80% of your property value in total — so usable equity is the gap between your current loan and that 80% ceiling.
Can I use home equity to buy an investment property?
Yes — this is one of the most common uses of equity in Australia. You use your home equity as a deposit (typically 20%) for an investment property, avoiding LMI. The equity loan is secured against your existing property, and the investment property loan is secured against the new property. Both loans then sit on your balance sheet.
How much equity do I need to refinance in Australia?
Most lenders require at least 20% equity (80% LVR) to refinance without paying LMI. Some will refinance at up to 90% LVR with LMI. If your equity has grown due to property value increases or loan repayments, refinancing can unlock better interest rates as well as giving you access to usable equity.
