Usable equity is generally 80% of your property's current value minus your outstanding loan balance. On a $900,000 property with a $400,000 mortgage, that is $320,000. Releasing it means refinancing to a larger loan and taking the difference as cash or as a separate facility. Lenders will ask what the money is for, and cash-out above roughly $50,000 usually requires evidence of the purpose.
Total equity and usable equity are different numbers, and the gap catches people out. Lenders will not normally let you draw beyond 80% of the property value without triggering Lenders Mortgage Insurance.
Worked example on a property valued at $900,000 with a $400,000 loan.
| Step | Calculation | Amount |
|---|---|---|
| Property value | Current lender valuation | $900,000 |
| Total equity | Value less loan balance | $500,000 |
| 80% of value | The usual cash-out ceiling | $720,000 |
| Usable equity | 80% of value less loan balance | $320,000 |
| New loan if fully drawn | Existing loan plus release | $720,000 |
Your own estimate of the property value is not what counts. The lender orders its own valuation, and a conservative result directly reduces the equity available. This is the single most common reason an equity release comes back smaller than expected.
Every lender asks what the funds are for. Some purposes are approved routinely; others require more evidence or are declined outright.
Deposit on an investment property, renovations to the existing home, or debt consolidation. These are standard and generally need only a brief statement of purpose.
Business use, share investment, or funds to a family member. Expect to provide quotes, a business plan, or a statutory declaration depending on the lender.
Speculative trading, cryptocurrency, or gambling. Some lenders also decline cash-out for tax debt without a formal ATO arrangement in place.
Under roughly $50,000, most lenders accept a stated purpose without documentary evidence. This threshold varies and is worth checking before you apply.
If you are releasing equity to invest, how the loan is structured determines whether the interest is deductible. Getting this wrong is expensive and difficult to unwind later.
This is tax structuring, and it sits outside credit advice. We set the loan up so your accountant has a clean structure to work with, but confirm the tax treatment with them before you draw the funds.
Releasing $320,000 over a 30-year term at 6% costs roughly $370,000 in interest if never paid down faster. If the funds are going into an appreciating or income-producing asset that can make sense. If they are funding consumption, it rarely does.
Generally 80% of your property value less what you still owe. On a $900,000 property with a $400,000 loan, that is $320,000 of usable equity. Going above 80% is possible at some lenders but triggers Lenders Mortgage Insurance on the whole loan.
Yes. Every lender requires a stated purpose. Below roughly $50,000 a statement is usually enough. Above that, expect to provide evidence such as renovation quotes, a contract of sale, or a business plan depending on the purpose and the lender.
They describe the same transaction. You refinance to a larger loan and take the difference in cash or as a separate facility. Some lenders use "equity release" for a redraw within an existing loan and "cash-out" for a full refinance, but the effect is the same.
It depends entirely on what the funds are used for, not on which property secures them. Interest on equity used to buy an investment property or fund a business is generally deductible; interest on equity used for a holiday or a car is not. Keep the split separate and confirm with your accountant.
Yes. The released amount is additional debt at your loan rate. On $320,000 at 6% over 30 years that is roughly $1,900 a month on top of your existing repayment. Lenders assess whether you can service the full new balance at a buffer rate before approving.
The lender will order a fresh valuation as part of the application, and that figure is what determines your usable equity. If the market has moved since you bought, this is usually where the available amount is confirmed — for better or worse.
Usable equity depends on the lender's valuation, your serviceability at the new balance, and your stated purpose. We will model all three before anything touches your credit file.
