Already own a home? You may be sitting on a deposit for your next property. Here's how equity access works - and the risks to understand first.

What is home equity?

Equity is the difference between what your property is worth and what you owe on it. If your home is worth $900,000 and your loan balance is $550,000, you have $350,000 in equity.

But not all of that equity is accessible. Lenders typically allow you to borrow against your property up to 80% of its value (without paying LMI). The portion above your current loan balance and up to 80% of the property value is called your usable equity.

Usable equity calculation
Property value$900,000
80% of property value$720,000
Current loan balance$550,000
Usable equity$170,000

This $170,000 could be used as a deposit for an investment property - without needing to save additional cash.

How accessing equity works

There are two main ways to access your equity for an investment property purchase:

Option 1: Cash-out refinance

You refinance your existing home loan to a higher balance, drawing out the equity as cash. This cash becomes your deposit for the investment property. You then take out a separate investment loan for the remainder of the purchase price.

✓ Simple structure✓ One lender✗ Increases home loan balance
Option 2: Equity loan (line of credit)

You set up a separate loan facility secured against your home, up to the usable equity amount. You draw from this facility to fund the deposit, and take out an investment loan for the balance. The equity loan and investment loan remain separate.

✓ Clean loan separation✓ Better for tax✗ More complex to set up

The right structure depends on your goals, tax position, and lender. We'll recommend the most appropriate approach for your situation.

How much investment property can you buy?

Your usable equity determines your deposit. But you also need to qualify for the investment loan based on your income and expenses - including the rental income from the investment property.

Example: Using $170,000 equity as a deposit
Available deposit (usable equity)$170,000
Deposit required (20% of purchase)$170,000
Maximum purchase price$850,000
Investment loan required$680,000

* Excludes stamp duty and purchase costs, which must be funded separately.

Note: you'll still need to fund stamp duty and other purchase costs (typically 3–5% of purchase price) from savings or additional equity. We'll calculate the full cost of your investment purchase upfront.

Risks to understand before you proceed

Using equity to invest is a powerful strategy - but it's not without risk. Here's what you need to understand before proceeding:

⚠️ Your home is security for both loans

If you can't service your investment loan and default, the lender can pursue your home as security. This is why it's essential to stress-test your repayments at higher interest rates before proceeding.

⚠️ Rental income isn't guaranteed

Vacancy periods, problem tenants, and unexpected maintenance costs can disrupt your cash flow. Ensure you have a buffer - at least 3–6 months of repayments - before investing.

⚠️ Property values can fall

If your investment property falls in value and your home also falls, your total equity position can deteriorate quickly. Diversification and conservative LVRs provide a buffer.

⚠️ Interest rate rises increase your repayments

With two loans, a rate rise hits you twice. We always stress-test your serviceability at rates 2–3% higher than current rates to ensure you can absorb increases.
