What is Loan Serviceability & Why is it Important?

If you’re thinking about buying a home in Australia right now, one of the first things a lender will look at is your loan serviceability.

For most new loan applicants, lending standards generally remain strict. This is partly due to the persistent 3% buffer, a rule from the Australian Prudential Regulation Authority (APRA), the government body that oversees banks and other lenders to make sure they operate safely and lend responsibly.

The APRA buffer requires lenders to stress-test loans at an interest rate three per cent higher than the interest rate you are actually being offered. This means lenders are checking whether you could still comfortably make your loan repayments if interest rates were to rise in the future. Understanding serviceability has always been important, but in today’s cautious lending environment, it is more critical than ever.

Lending standards are stricter now than they were a few years ago. Lenders are more careful about how much they will lend relative to your income, existing debts, and ongoing expenses. This means that even borrowers with a solid deposit may find that the amount they can borrow is less than they expected, so having a clear understanding of serviceability is key to realistic planning and budgeting.

How do lenders assess serviceability?

Lenders consider several key factors when deciding how much you can borrow and whether you will be able to make the repayments if interest rates increase down the track. They look at your income, including salary, bonuses, rental income from an investment property, or other reliable sources. Stability is particularly important in today’s cautious environment. They also examine your day-to-day expenses, including living costs, existing debts such as a car loan or personal loan, credit card limits, and regular spending habits. In short, it is the lender asking, "Can this person handle this loan without getting into financial trouble?"

 Lenders also consider the type of loan you apply for and the terms and conditions of the loan. That means the structure of the loan, its term length – whether it is 25 or 30 years of repayments, the repayment type – whether you will make weekly, fortnightly or monthly repayments, and whether it is principal and interest or interest-only. All of these are taken into account when a lender is working out their serviceability calculations.

Why serviceability matters more than ever

Even if you have a deposit and a good credit score, current lending standards are strict, and a lender can still decline your application if your serviceability does not meet their criteria. Understanding serviceability now can save time, stress, and surprises. With interest rates higher than in recent years and the APRA buffer in place, being realistic about how much you can borrow is essential.

Tips to strengthen your application

There are several strategies you can use to improve your serviceability and increase your borrowing power. Reducing existing debt, such as paying down personal loans or credit cards and reducing your credit limit, makes a significant difference. Demonstrating stable income through regular salary, bonuses, or rental income also strengthens your case.

Keeping your living costs under control shows lenders that you are financially responsible. Avoiding new debts or large purchases before applying for a loan is another way to improve your serviceability. Finally, considering a co-borrower, such as a partner with a stable income, can increase the total borrowing capacity and make it easier to meet lender requirements.
