“How much equity can I access” has two answers, and the gap between them is where disappointment lives. There is the equity you have, and there is the smaller amount a lender will actually release.
Equity you have is value minus what you owe. Usable equity is less than that, because the lender keeps a margin, and even usable equity is only released if you can service the larger loan.
These two terms get used interchangeably and they are not the same thing, which is why “how much equity can I access” gets answered two different ways. The difference is the margin the lender retains.
| Figure | How it is worked out | What it is good for |
|---|---|---|
| Available equity | The lender’s assessed value minus your loan balance | Understanding your position. It is not the amount you can borrow |
| Usable equity | Commonly eighty per cent of the assessed value minus your loan balance | The realistic starting point for a release |
| Above eighty per cent | Possible with some lenders, with lenders mortgage insurance on the increase | Where the premium is worth paying for the extra funds |
| What you actually receive | Usable equity, capped by what your income will service | The only figure that matters at the end |
The eighty per cent convention is a common starting point rather than a rule, and individual lenders set their own. Above it the insurance comes back into the picture, which is a cost rather than a prohibition.
Work “how much equity can I access” in three steps, and use conservative numbers at each one.
The honest answer to “how much equity can I access” starts with the lender’s number rather than yours. First, take the value a lender would assess, not the figure an agent mentioned.
Second, take eighty per cent of it. Third, subtract your current loan balance. What remains is your usable equity.
On a property assessed at a million dollars with six hundred thousand owing, eighty per cent is eight hundred thousand, so two hundred thousand is usable. Available equity on the same numbers is four hundred thousand.
That gap, between two hundred and four hundred thousand, is what surprises people. It is not the lender being difficult. It is the margin that keeps the loan inside the ratio where no insurance is required.
Run your own figures on the borrowing power calculator and see the equity release guide.
“How much equity can I access” rests entirely on the assessed value, and that is the lender’s number rather than yours. It is also the single most common reason an equity release comes back smaller than expected.
Lenders use several methods. An automated estimate from sales data, a desktop assessment, or a full inspection by a valuer, and which one applies depends on the lender, the loan size and the property.
An automated estimate on an unusual property, a large block or a recently renovated home frequently lands low, because the model has nothing comparable to work from.
Where that happens, a full valuation is sometimes worth requesting, and evidence of the renovation and comparable sales helps. See why applications get declined.
Having usable equity does not mean you can borrow it, which is the second half of “how much equity can I access”. The release is a new loan, assessed on your income and commitments like any other.
So “how much equity can I access” is capped twice: once by the property, and again by what your income will service with the serviceability buffer applied above the rate you will actually pay.
That second cap catches people whose property has grown faster than their income. Equity on paper and borrowing capacity are different things and they move independently.
Credit card and overdraft limits reduce the second figure too, because they are assessed at their limit rather than their balance. See how the buffer works and what lenders count and shade.
“How much equity can I access” is only half the question. What you intend to do with it changes the structure, and sometimes the answer.
A renovation on the same property is the simplest case. The lender is lending against an asset it already holds, for work that may increase its value.
A deposit on an investment property is next, and there the purpose matters because the new loan is assessed as investment lending with its own rules.
A debt consolidation needs more care. Rolling short-term debt into a thirty-year loan lowers the repayment and can increase the total interest paid, which is a trade-off worth seeing in figures before you make it.
Some purposes narrow the lender panel. Business use and lending to family are both treated differently, and it is better to say so at the start than to be asked at assessment. See using equity to buy an investment.
Sydney values have softened, and usable equity is calculated from today’s assessed value rather than the peak. That reduces the figure with no change to your loan at all.
Two things still work in your favour. Every principal repayment reduces the balance, which lifts usable equity directly, and extra repayments accelerate it.
The Reserve Bank’s October 2026 Financial Stability Review puts borrowers who owe more than their property is worth at under one per cent, while noting that downside risks to prices remain.

As a starting point, eighty per cent of the lender’s assessed value minus your current loan balance, which is your usable equity.
More is possible with some lenders where lenders mortgage insurance is paid on the increase. Whatever that figure comes to, the release is still capped by what your income will service.
Available equity is the assessed value minus your loan balance, which describes your position but is not what you can borrow. Usable equity is commonly eighty per cent of the assessed value minus the balance, which is the realistic starting point.
On a property assessed at a million dollars with six hundred thousand owing, those two figures are four hundred thousand and two hundred thousand.
Up to your usable equity, which is commonly eighty per cent of the assessed value less your loan balance, and capped again by what your income will service.
No sale is involved: an equity release increases your borrowing against the property you already own, either as a loan increase or a separate split. It is a new loan, so it is assessed on your income as well as the property.
Not always. Lenders use automated estimates from sales data, desktop assessments and full inspections, and which applies depends on the lender, the loan size and the property.
An automated estimate often lands low on an unusual property, a large block or a recently renovated home, in which case requesting a full valuation with evidence of the work can be worthwhile.
Usable equity is calculated from today’s assessed value, so a softer market reduces the figure without your loan changing at all.
Principal repayments work the other way and lift it directly. Where a release comes back short, paying down the balance is often more effective than looking for a higher valuation.
Usually one of three reasons: the eighty per cent margin the lender retains, an assessed value below the figure you had in mind, or a borrowing capacity that caps the release below your usable equity.
The third catches people whose property has grown faster than their income, because equity and capacity move independently of each other.
