How to Buy Your Second Property Using Equity in Australia

Buying your first property requires years of disciplined saving. Buying your second property can be a very different experience. If your first property has grown in value and your loan has reduced through repayments, you may be sitting on a substantial pool of accessible equity that can serve as the deposit for your next purchase.

This guide explains how to use equity from an existing property to fund a second purchase, how the process works practically, what the risks are and what loan structure considerations apply.

Why Equity Is the Key

Most people who buy their first home understand the deposit requirement intuitively. Less intuitive is the realisation that after a few years of ownership, the equity in your first property can do the work that took years of saving to accumulate.

If you purchased a home five years ago for $600,000 with a $120,000 deposit (20 per cent), your loan was $480,000. If the property is now worth $820,000 and you have reduced the loan to $440,000 through repayments, your equity is $380,000. At 80 per cent LVR, your accessible equity is $820,000 x 0.80 minus $440,000, which equals $216,000.

That $216,000 can become the deposit for a second property. You have not had to save it separately. Your existing property has built it for you.

How to Access the Equity

There are two main approaches to releasing equity for a second property purchase.

Refinancing the First Property to a Higher Balance

You refinance your existing loan to increase the balance by the amount of equity you want to access. The additional funds are held in your account or applied at settlement of the second property.

For example, if you want to access $150,000 in equity and your current loan is $440,000, you refinance to a $590,000 loan on the first property.

Using the Existing Property as Additional Security

Rather than drawing the equity as cash, you can use your first property as additional security for the new loan on the second property. This can allow you to borrow a higher proportion of the second property's value than your deposit alone would allow.

This is called cross-collateralisation. It involves linking two properties as security for your loans, which creates a simpler structure initially but can complicate future transactions. Most experienced mortgage brokers recommend against cross-collateralising unless there is a specific reason to do so, because it reduces your flexibility later.

The cleaner structure is to draw the equity from the first property separately and use the released funds as a standalone deposit on the second.

What the Numbers Look Like in Practice

Continuing the example above: you have $216,000 in accessible equity on your first property. You want to buy a $700,000 investment property.

You draw $140,000 from your first property's equity (bringing that loan to $580,000).

You use $140,000 as the deposit on the second property, representing a 20 per cent deposit.

You take out a separate investment loan for $560,000 on the second property.

Your combined loan balances are now $580,000 plus $560,000, totalling $1,140,000.

The investment loan interest is tax-deductible. The owner-occupier loan interest is not. They are kept completely separate.

Serviceability: Can You Afford Both Loans?

Having the equity is only half the equation. You also need to demonstrate to the lender that you can service both loans simultaneously under the lender's assessment criteria, which includes a three per cent interest rate buffer above the actual rate.

Your serviceability assessment includes your income, existing loan repayments, the new investment loan repayments, an assessment of the rental income from the new property (typically at 70 to 80 per cent of the expected rent) and all other financial commitments.

If your income supports the combined debt level and your APRA DTI ratio (total debt divided by gross income) is below six, most lenders will be comfortable proceeding.

Loan Structure for the Second Property

The loan structure for your investment property should be kept completely separate from your owner-occupier loan. Key principles:

Investment loan in interest-only: maximise the tax-deductible interest while directing any extra cash to the non-deductible owner-occupier loan.

Offset account on the owner-occupier loan: keep surplus cash in the offset to reduce non-deductible interest.

Do not cross-collateralise unless specifically advised to do so.

Use separate lenders if possible, or at minimum separate loan accounts, so the ATO can clearly distinguish deductible from non-deductible interest.

Timing: When Is the Right Time to Access Equity?

The right time to access equity for a second purchase depends on three conditions being met simultaneously:

Your existing property has sufficient equity to fund the deposit without pushing it above 80 per cent LVR.

Your income supports the combined loan repayments under the lender's serviceability assessment.

The second property is a sound investment at the prevailing market conditions.

The third condition is the one most often overlooked. Accessing equity to buy a poorly selected property in a market with limited growth prospects, just because the equity is available, is not a strategy. It is a way to put good equity to work in a bad investment.
