Understanding Credit Scores and Home Loan Applications

Your credit score affects every part of your home loan application, from the interest rate you're offered to whether you're approved at all.

Lenders use your credit score as a shorthand for risk. A lower score often means a higher rate, a reduced loan amount, or in some cases, a referral to a specialist lender. A strong score can unlock lower rates and better loan features. The difference in what you pay depends on how lenders price their home loan products and where your score sits within their risk bands.

What a Credit Score Actually Measures

A credit score is a number, typically between 0 and 1,200, that represents how reliably you've managed credit in the past. It's calculated by credit reporting bodies like Equifax, Experian and Illion using your credit report, which includes details like how many accounts you've opened, whether you've missed payments, and how much credit you've applied for recently. A higher score tells lenders you've consistently met your repayment obligations. A lower score suggests there's been a default, late payment, or frequent credit enquiry that raises concern.

In our experience, buyers in Leederville are often surprised that a mobile phone contract or buy-now-pay-later account contributes to their credit file. Even if you've never had a home loan or credit card, your report may already contain several listings.

How Credit Scores Affect Your Interest Rate

Lenders assign a risk weight to every home loan application, and that weight influences the interest rate they offer. A borrower with a score above 700 will generally qualify for a lender's standard advertised variable rate or fixed rate. A borrower with a score between 500 and 700 may receive a slightly higher rate or be asked to provide a larger deposit. A score below 500 often means the application is declined by major lenders, or the buyer is directed to a non-bank lender with higher rates and fewer offset or redraw features.

Consider a buyer purchasing a townhouse near Leederville Oval. With a score of 750, they're offered a variable interest rate with a full offset account and the option to fix part of the loan. With a score of 580, the same buyer might face a rate that's 0.5 to 1.0 percentage points higher, no offset, and limited ability to split the loan between variable and fixed. Over a 30-year term, that rate difference can cost tens of thousands of dollars in additional interest.

How Leederville Buyers Can Improve Their Credit Position Before Applying

You can request a copy of your credit report from Equifax, Experian or Illion at no charge once every 12 months. Review it carefully for errors, such as accounts that don't belong to you or defaults that have been listed incorrectly. If you find a mistake, contact the credit reporting body and the credit provider to have it corrected.

Paying down existing debts, closing unused credit cards, and avoiding new credit applications in the months before you apply for a home loan will all support a stronger application. Lenders also assess your borrowing capacity by looking at your current liabilities, so even a card with a zero balance but a $10,000 limit can reduce the loan amount you're approved for. If you're not using it, close it.

Leederville's proximity to the CBD and Northbridge means many residents rely on public transport and may not have a car loan, which can actually work in your favour when applying for finance. Lower ongoing commitments leave more room in your borrowing capacity assessment.

Credit Score Bands and What They Mean for Loan Approval

Most lenders use the following bands as a guide, though the exact thresholds vary between institutions. A score of 800 or above is considered excellent and gives you access to the widest range of home loan options and the lowest rates. A score between 700 and 799 is very good and will qualify you for most standard home loan products. A score between 625 and 699 is average, and while you'll likely be approved, you may face a higher rate or stricter conditions. A score between 510 and 624 is below average, and approval often depends on the strength of your income, deposit and employment history. A score below 510 is considered low, and you'll generally need to work with a broker who has access to specialist lenders.

If you've recently moved to Leederville from interstate or overseas, your Australian credit file may be limited or non-existent. In that case, lenders will ask for additional documentation such as bank statements from your previous country of residence, evidence of rental payments, or references from previous credit providers. Some lenders have specific programs for expat loans that take this into account.

Defaults, Judgments and Bankruptcies

A default is recorded on your credit file when you fail to pay a debt of $150 or more and the creditor has taken steps to recover it. Defaults remain on your file for five years from the date they're listed, even if you pay them in full. A paid default is viewed more favourably than an unpaid one, but it will still affect your application. A judgment or court order has a similar impact and also remains for five years. Bankruptcy stays on your file for five years from the date you become bankrupt, or two years from the date your bankruptcy ends, whichever is later.

If you've had a default in the past, it doesn't mean you can't get a home loan. It does mean you'll need to provide a clear explanation, evidence that the debt has been resolved, and proof that your financial position has since improved. We regularly see this with buyers who had a utility or telco bill go to collections years ago without realising it. Once it's paid and explained, many lenders will still approve the application, particularly if the rest of the credit file is clean.

Joint Applications and Mixed Credit Scores

When you apply for a home loan with a partner or co-borrower, both credit scores are assessed. Some lenders take the lower of the two scores as the basis for pricing and approval. Others will weight both scores and assess the application based on the combined risk profile. If one applicant has a strong score and stable income, that can offset a weaker score from the other applicant, but it's not guaranteed.

In a scenario where one partner has a score of 780 and the other has a score of 620 due to a missed payment on a previous personal loan, the lender may approve the application but apply a higher interest rate or require a larger deposit. Alternatively, the applicant with the stronger score could apply alone, though that would mean the assessment is based on one income rather than two, which may reduce the amount you can borrow. A broker can model both options and recommend the approach that gives you the lowest rate and highest loan amount based on your circumstances.

For first home buyers in Perth, understanding how joint credit assessments work is particularly important if you're pooling income and savings to reach the deposit threshold.

How Often Should You Check Your Credit Score

You should check your credit report at least three to six months before you plan to apply for a home loan. This gives you time to correct errors, pay off small debts, and avoid any new credit enquiries that could lower your score. Each time you apply for credit, whether it's a credit card, car loan, or even some buy-now-pay-later services, a hard enquiry is recorded on your file. Multiple enquiries in a short period can signal financial stress and lower your score.

If you're considering a home loan refinance or exploring your options with a broker, ask them to check your eligibility without submitting a formal application. Many brokers have access to tools that allow them to assess your borrowing capacity and compare lenders without triggering a credit enquiry. Once you've chosen a lender and are ready to proceed, the formal application and enquiry are submitted.
