How to Improve Your Credit Score Before Applying for a Home Loan (Australia 2026)

If you are planning to apply for a home loan in 6–12 months, your credit score is worth paying attention to now. Here are the most effective steps to improve your credit profile before you apply.

Step 1: Check Your Credit Report First

Before trying to improve your score, understand where you stand. Pull your credit report from all three bureaus (Equifax, Experian, illion) and check for:

  • Errors in personal details
  • Defaults or listings you don’t recognise
  • Paid defaults still showing as unpaid
  • Old entries that should have aged off (5+ years)

Fixing errors can immediately improve your score.

Step 2: Pay All Bills On Time — Every Time

Under Comprehensive Credit Reporting (CCR), your repayment history on credit accounts (credit cards, personal loans, buy-now-pay-later) is recorded and affects your score.

The single most effective thing you can do: Set up direct debits for all credit accounts (minimum repayments at least) so you never miss a payment due date.

Even one 14-day late payment can reduce your score under CCR. A pattern of on-time payments over 12–24 months significantly improves your score.

Step 3: Reduce Credit Card Limits

Credit card limits are counted as full potential debt by Australian home loan lenders — not just the amount you currently owe. A $20,000 credit card limit reduces your borrowing capacity by approximately $100,000 on a home loan (because the lender assumes the card could be maxed out at any time).

Before applying:

  • Cancel credit cards you don’t need
  • Reduce limits on cards you keep to the minimum you actually need (e.g., reduce from $15,000 to $5,000)

Reducing credit limits also improves your credit utilisation ratio — lower utilisation is better for your score.

Step 4: Don’t Apply for New Credit

Every credit application — credit card, buy-now-pay-later, personal loan, car loan — creates a hard enquiry on your credit file and temporarily reduces your score. Multiple applications in quick succession are a significant red flag to lenders.

In the 6–12 months before applying for a home loan:

  • Avoid new credit card applications
  • Avoid increasing credit limits
  • Avoid personal loans or car finance applications
  • Avoid buy-now-pay-later accounts (Afterpay, Zip, Humm, etc.) if they require a credit enquiry

Step 5: Pay Off (or Reduce) Outstanding Defaults

If you have an unpaid default on your file:

  • Paying it does not remove the listing (it remains for 5 years from listing date)
  • But it changes the listing from “unpaid” to “paid” — which lenders view more favourably
  • Some non-bank lenders require defaults to be paid before they will approve a home loan

Check whether any listed defaults are paid in full and confirm this is reflected on your credit file.

Step 6: Build a Positive Payment History

Under CCR, every month of on-time payments on your existing credit accounts adds positive data to your file. The longer your history of responsible credit management, the stronger your credit profile.

Practical actions:

  • Keep at least one credit card active and pay it off in full monthly
  • Pay all utility, phone and internet bills on time (telcos report to credit bureaus)
  • Maintain repayments on any existing personal loans or car loans

Step 7: Don’t Close All Your Credit Accounts

Closing all credit accounts may seem prudent — but having no credit history can make it difficult for lenders to assess you. Maintaining at least one long-standing credit account in good standing can be beneficial.

However, the priority for home loan applicants is reducing limits and outstanding balances — not preserving many accounts.

How Long Does Credit Improvement Take?

ActionTypical time to see improvement
Fixing credit report errorsWeeks (after bureau investigation)
Reducing credit enquiries (stop applying)3–6 months for enquiries to age
Building on-time payment history6–12 months of consistent data
Paying an unpaid defaultImmediately updates the listing
Default aging off file5 years from listing date

What You Cannot Speed Up

Some things simply take time:

  • Defaults must age off — there is no shortcut (unless the listing is an error)
  • Bankruptcy remains on file for 5–7 years
  • Court judgements remain for 5 years

In these situations, a mortgage broker can identify lenders (typically non-bank or specialist) who may still consider an application despite adverse history — usually at higher rates.

Frequently Asked Questions

Does getting a credit score check affect my score?

No — checking your own score is a soft enquiry. Only lender credit applications are hard enquiries.

Can I pay a company to fix my credit score?

Be cautious. Credit repair companies in Australia cannot remove legitimate listings — only errors can be removed, and you can dispute those yourself for free. If a company promises to “erase” a genuine default, this is not achievable. Refer to ASIC MoneySmart’s guidance on credit repair.

Should I fix my credit or save a bigger deposit first?

Both are important — but if you have major adverse credit listings, the credit profile is likely the binding constraint. A larger deposit cannot overcome a very poor credit history for major bank approval.

Negative listings that are legitimate cannot be removed — only errors can be disputed. For advice tailored to your situation, speak with a licensed mortgage broker. Find one through MoneySmart.
