Equity Unlock FAQs

What is usable equity in property?

Usable equity is the portion of your property's value that a lender will allow you to borrow against without requiring LMI. Most lenders cap this at 80% of the property's current value. Formula: Usable equity = (Property value × 80%) − Outstanding loan. On an $800,000 property with a $400,000 loan: usable equity = $640,000 − $400,000 = $240,000.

How do lenders calculate how much equity I can release?

Lenders order their own valuation of your property (which may differ from what you think it's worth) and lend up to 80% of that assessed value. Your releasable equity is: (Assessed value × 0.80) − outstanding loan balance. Note that serviceability — your income relative to total debt — is a separate hurdle you also need to clear.

What is the 80% LVR rule for equity release?

The 80% LVR threshold is the point at which most lenders require LMI (Lender's Mortgage Insurance). Keeping your total borrowings at or below 80% of the property's value means no LMI, which typically saves thousands. This calculator defaults to 80% but lets you model 60%, 70%, or 90% LVR scenarios.

Can I use equity as a deposit for an investment property?

Yes — and this is the core strategy for most portfolio-building investors. You release usable equity from your existing property (via refinance, line of credit, or equity loan) and use it as the deposit on your next purchase. The lender then holds security over both properties. You'll still need to pass serviceability testing on the total combined debt.

How long does it take to access equity in Australia?

Typically 2–6 weeks. The process involves a lender valuation, credit assessment, and loan documentation. If you refinance to a new lender, allow up to 8 weeks. A mortgage broker who already has your financials on file can often get this done in 2–3 weeks. Some lenders offer pre-approvals on equity access, which you can activate when you find a property.
