Home equity can fund the deposit and costs of a second property, but only if your borrowing capacity and cash flow support the extra debt. For Truganina homeowners, the first step is to work out how much equity is usable and how much repayment you can carry comfortably.

How Does Refinancing to Release Equity Work?

Refinancing to release equity means increasing your home loan, or moving to a new lender, so you can borrow against the value your home has built up. The extra funds are paid to you as cash, often for use as a deposit on another property.

Equity is the difference between your property's value and what you owe. A lender will value your home and usually limit total borrowing to a percentage of that value. This is called the loan to value ratio, or LVR. Many lenders set their limit at around 80% of value for standard lending, although policies differ between lenders. Borrowing above that level can mean paying lenders mortgage insurance, which is a cost to weigh up.

The main trade-off is that your home becomes security for a larger debt. If the investment does not perform as planned, your family home is still on the line.

How Much Equity Can You Actually Use?

Usable equity is the amount you can borrow above your current loan while staying within the lender's LVR limit. It is not the full difference between value and loan balance.

As an example, a home valued by a lender at $700,000 with an 80% limit allows total borrowing of up to $560,000. If the loan balance is $400,000, usable equity is $160,000. That figure still needs to pass the lender's assessment of your income, expenses and other debts.

A valuation can come in higher or lower than you expect, so treat any early estimate as a starting point only. Our borrowing capacity page explains what lenders look at when assessing how much you can borrow.

Should You Use Equity for the Deposit or Fund the Whole Purchase?

A common approach is to use equity for the deposit and costs, then take a separate loan for the rest of the purchase. This keeps the debts distinct and gives you more flexibility later.

When equity is released, you generally have the existing home loan, the released amount and a new investment loan. The released amount used for the investment should be set up as its own split, separate from the existing home loan balance. Interest deductibility follows how the borrowed money is used. Interest on each split is deductible only to the extent the funds were used to produce rental income. If the released amount sits in the same account as your private home debt, the loan is mixed-purpose and the interest has to be apportioned. Confirm the structure with your accountant before settlement. No tax outcome is certain.

The cost of this approach is higher total debt and two sets of repayments. Your serviceability, meaning your ability to repay as assessed by the lender, must cover both.

Equity Release Example: A Truganina Family Buying an Investment Property

Consider a Truganina couple who owe $400,000 on a home that a lender values at $700,000. They want to buy an investment property and need $120,000 for the deposit and purchase costs.

With an 80% limit, their usable equity is $160,000. They release $120,000, which lifts the home loan to $520,000. That is within the $560,000 limit, so no lenders mortgage insurance applies on the home loan. They set up the $120,000 as its own split, separate from the $400,000 home balance.

At the illustrative rate of 6.75% p.a., the extra $120,000 over a 30-year term adds about $778 a month to their home loan repayments. This is a rough figure for comparison only, and actual rates vary by lender and loan. They then confirm the investment loan repayments, expected rent and other holding costs. After the numbers show they can meet both loans with a buffer, they proceed. Their outcome rests on that buffer, not on the property's future growth.

What Risks Should You Weigh Before You Borrow Against Your Home?

The main risks are higher repayments, rate changes and a fall in property values. Each of these can reduce the buffer you rely on.

If your loan has a variable rate, repayments can rise when lenders adjust their rates. Vacancies in the rental property mean you cover the full cost yourself for a time. Property values can also fall, which affects your equity and your options if you later want to refinance.

A sensible step is to test your repayments at a rate higher than today's, and to keep savings aside for several months of costs. An offset account can help hold that buffer while reducing interest, though some loans with offset features carry higher fees or rates.

Is Refinancing Worth It If You Already Have a Fixed Rate?

Refinancing a fixed loan before it ends can trigger break costs, so check these first. Whether the cost is worth paying depends on the size of the loan and the time left on the fixed term.

If your fixed period is close to ending, waiting may allow you to release equity without a break fee. Our page on fixed rate expiry covers what to review as the end date approaches. A loan health check can also show whether your current loan suits your plans.

Refinancing also brings its own costs, such as application or discharge fees, depending on your lender. These should be weighed against any change in rate or features.

Frequently Asked Questions

How much equity can I use to buy a second property?

Usable equity is the amount you can borrow above your current loan while staying within the lender's LVR limit, often around 80% of your home's value. Your income and expenses must also support the extra debt.

Should I use equity for the deposit only?

Many buyers use equity for the deposit and costs, then take a separate investment loan for the remainder. The released amount should be set up as its own split, separate from your existing home loan balance, and you must be able to service all the loans.

Can I deduct the interest on equity I release?

Interest on each split is deductible only to the extent the funds were used to produce rental income. Keep the released amount in its own split and confirm the structure with your accountant before settlement, as no tax outcome is certain.

What are the main risks of borrowing against my home?

Repayments may rise, the property may be vacant, and values can fall. Your family home also secures the larger debt, so keep a buffer.
