How to Improve Your Credit Score Before Applying for a Mortgage

When you're contemplating the purchase of a home, your credit score becomes more than just a number — it's a reflection of your financial reliability and can be the key to unlocking favourable mortgage terms.

1. Obtain and Scrutinise Your Credit Report

Before you can improve your credit score, you need to understand where you currently stand. Australians are entitled to a free credit report annually from major credit reporting agencies (Equifax, Experian, illion). Request your report and check it carefully for inaccuracies or outdated information. Dispute any errors you find, as these can unjustly drag down your score.

2. Pay Bills on Time

Your payment history is a significant component of your credit score. Ensure that you consistently pay all your bills on time — utilities, phone contracts, and other recurring expenses. Setting up direct debits can help you avoid missing payments. Even a single late payment can leave a mark on your credit history.

3. Reduce Existing Debt

Lenders look at your debt-to-income ratio as an indicator of your ability to manage a new mortgage. Work on paying down existing debts, particularly high-interest credit cards. Aim to keep your credit card balances below 30% of your credit limits. Demonstrating that you can manage debt responsibly reflects positively on your credit score.

4. Limit Credit Applications

Every time you apply for credit, a hard inquiry is recorded on your credit report. These inquiries can temporarily lower your score, so avoid applying for new credit cards or loans in the months leading up to your mortgage application. If you must apply for credit, do so sparingly.

5. Keep Old Credit Accounts Open

The length of your credit history affects your credit score — longer histories are usually seen as more favourable. If you have old credit accounts with good repayment records, consider keeping them open. This demonstrates long-term financial stability to lenders.

6. Diversify Your Credit Mix

Having a mix of different types of credit accounts — personal loans, credit cards, car loans — can sometimes help your credit score by showing you can manage different types of credit. However, don't take on more credit than you can handle purely to improve your mix.

7. Monitor Your Credit Score Regularly

Keep an eye on your credit score and report throughout the year. Monitoring your credit can help you catch and address issues quickly, as well as understand how your financial behaviour affects your score. There are various online services that allow you to check your credit score without impacting it.

Improving your credit score is a gradual process, but the effort is worth it — better credit means more lender options and more competitive rates. If you're planning to apply for a mortgage in the next 6–12 months, start your credit health check now.
