Learning how to use equity to buy investment property means understanding one number: your usable equity. It is not what your home is worth minus what you owe, and confusing the two is where most plans fall apart.
How to use equity to buy investment property works like this: your lender revalues your home, calculates eighty per cent of that value, subtracts your existing loan, and releases the difference as a separate split. That release funds the deposit and costs on the next purchase.
Equity is not money until a lender agrees it is. The valuation decides everything, and it is the one part of the process most owners never think to prepare for.
In this example the usable equity calculation comfortably covers the purchase. Note the difference between total equity of $660,000 and usable equity of $420,000.
This distinction catches out almost everyone learning how to use equity to buy investment property for the first time.
Total equity is your value less your loan. The usable equity calculation applies the lender’s eighty per cent ceiling first, which is why a home worth $1.2 million with a $540,000 loan gives you $420,000 to work with rather than $660,000.
When working out how to use equity to buy investment property, the structure matters more than the amount.

When both properties secure one loan, selling either requires the lender’s consent and a full reassessment. Releasing equity later becomes harder. Moving one property to a different lender becomes considerably more difficult.
Knowing how to use equity to buy investment property is not the same as affording it, and lenders test both.

Each of these errors in how to use equity to buy investment property costs flexibility or money.
Four numbers before you look at a single listing.
Your lender revalues your home, calculates eighty per cent of that value, subtracts your existing loan, and releases the difference as a separate loan split. That release funds the deposit and purchase costs on the investment.
Eighty per cent of $1.2 million is $960,000. Subtract your existing loan to find your usable equity. With a $540,000 loan, that leaves $420,000 available, rather than the $660,000 of total equity.
Not a cash deposit. The released equity serves as your deposit and covers purchase costs. You still need to service the combined debt, which is assessed at roughly three percentage points above the actual rate.
Total equity is your property value less your loan. Usable equity applies the lender’s eighty per cent ceiling first, then subtracts the loan. Usable equity is always the smaller and the only figure that matters.
A separate split, always. Redrawing for investment purposes creates a mixed purpose loan that is difficult to apportion for tax. A dedicated split keeps the interest clearly traceable to the investment.
It means both properties secure the same loan. Generally avoid it. You lose the ability to sell or refinance one property independently, and a fall in one property’s value can affect borrowing against the other.
Yes. Reforms announced on 12 May 2026 are now law. Established residential properties purchased after 7:30pm that day lose the ability to offset rental losses against salary from 1 July 2027. Eligible new builds remain exempt.
There may be little available. You can borrow above eighty per cent, but lenders mortgage insurance applies to the released amount and the cost rises sharply. Waiting for growth or paying down the loan is often better.
