Everything You Need to Know About Credit Scores & Home Loans

Your credit score shapes which lenders will work with you and what rate they'll offer.

Most people assume they either qualify or they don't. In reality, your credit file sits on a spectrum that determines loan amount, interest rate, and whether you'll need a specialist lender or can access mainstream products. A score of 650 might get you approved with one lender at 6.5%, while a score of 750 opens up twenty lenders offering 5.9%. The difference compounds over thirty years.

Mandurah has a higher proportion of self-employed tradies and small business owners than Perth's northern suburbs, and many carry older defaults from the mining downturn or early business years. That history doesn't disqualify you, but it does change the approach.

What Actually Shows Up on Your Credit File

Your credit file lists every credit application you've made in the past five years, every credit account you hold, and any defaults, court judgments, or bankruptcy events.

Lenders don't just see a single number. They see the timeline. A default paid two years ago reads differently to one paid last month, even if both still appear on the file. Multiple loan applications in a short window suggest either desperation or rate shopping, depending on context. A lender reviewing your file sees whether you've been knocked back elsewhere recently, whether you're consistently late on repayments, and whether your spending patterns have changed.

Consider a buyer in Mandurah who applied for finance with their bank, got declined, then applied with two online lenders in the same week. Each application appears as a hard enquiry. By the time they reach a broker, three declines are already visible. That doesn't mean they can't get approved, but it narrows the field. Some lenders won't touch a file with three recent knockbacks. Others will, but at a higher rate or with a larger deposit required.

When you apply for a home loan, the lender pulls your file within 48 hours. If there's something unexpected, the approval stalls until you explain it. Defaults under $500 are often overlooked if they're paid and old. Defaults over $5,000, especially unpaid ones, require a different strategy.

How Your Score Changes Which Lenders You Can Use

A score below 600 rules out most major banks, but it doesn't rule out home ownership.

Specialist lenders exist specifically for borrowers with impaired credit. They charge more, usually 1% to 2% above standard variable rates, and they're stricter on deposit size. You'll typically need at least 15% to 20% genuine savings, sometimes more if the default is recent or unpaid. But they will lend, and once you've rebuilt your credit over two to three years, refinancing back to a mainstream lender brings your rate down.

Scores between 600 and 700 sit in the middle ground. Some banks will approve you, others won't. Rate discounts shrink. A borrower with a 750 score might negotiate a 0.8% discount off the advertised variable rate. Someone with a 640 score gets the standard rate or a token 0.1% reduction. Over a $400,000 loan, that difference costs around $2,800 a year.

Above 700, you have options. Above 800, you have leverage. Lenders compete for high-score borrowers because they default less often and cost less to service. That competition translates to better rates, lower fees, and more willingness to waive Lenders Mortgage Insurance (LMI) in borderline cases.

The Enquiry Problem That Catches People Out

Every time you apply for credit, it leaves a mark.

Hard enquiries from loan applications stay visible for five years. One or two enquiries in a year look normal. Six enquiries in three months look chaotic. Lenders assume you've been declined multiple times or you're taking on more debt than your income supports. Either way, it raises questions.

Rate shopping doesn't help if you're doing it by submitting full applications. Some borrowers think applying with five banks will get them five offers to compare. Instead, they get five enquiries on their file and possibly five declines if their situation was marginal to begin with. Once that pattern appears, even lenders who might have said yes initially start declining because the file looks worse than it did a month earlier.

Brokers submit one application to one lender at a time, based on a read of your situation and which lender is most likely to approve at the rate you need. If that lender declines, we pivot to another. But we don't scatter applications across ten lenders and hope one sticks. That approach destroys files.

If you've already accumulated multiple enquiries, wait. Let three to six months pass before applying again. The enquiries don't disappear, but they age, and lenders view older enquiries less harshly than fresh ones. Use that time to pay down debt, close unused credit cards, and if there's a default, pay it and get a letter of clearance.

Defaults, Judgments, and What You Can Actually Do

A default doesn't mean you're locked out for five years, but it does mean you need to address it before applying.

Paid defaults are workable. Unpaid defaults are harder. Some lenders will overlook a paid default if it's small, old, and isolated. A single $300 phone bill from three years ago won't stop most approvals. A $10,000 unpaid credit card default from last year will.

If you have an unpaid default, pay it before you apply. Get written confirmation from the creditor that it's settled, then attach that to your loan application. The default still shows on your file, but the fact that it's marked as paid changes how lenders assess risk. Some lenders require a 12-month wait after payment before they'll approve you. Others will approve immediately if everything else is solid.

Court judgments and bankruptcies sit in a different category. A discharged bankruptcy usually requires a two-year wait before any mainstream lender will consider you. During that period, specialist lenders are the only option, and they'll want 25% to 30% deposit. Judgments depend on the amount and whether they've been satisfied. A small judgment that's been paid and is over two years old might not block approval. A recent or large one will.

Mandurah's property market has a solid mix of established homes in areas like Halls Head and Meadow Springs, where buyers often refinance to access equity for renovations or investment. If your credit file has old marks but you've been stable since, building equity in an owner occupied home loan over two to three years gives you options when it's time to refinance or invest.

Improving Your Position Before You Apply

Your credit score isn't fixed. You can move it, but it takes time.

Pay everything on time for six months. That includes phone bills, utilities, and any existing loans. Late payments show up on your file if they're reported by the creditor, and they signal unreliability. On-time payments don't improve your score overnight, but they stop it from getting worse and they demonstrate stability to a lender reviewing your file manually.

Close credit cards you're not using. Even if the balance is zero, the limit counts against your borrowing capacity. A $10,000 credit card limit reduces what you can borrow by around $50,000, depending on the lender's assessment rate. If you've got three cards with a combined limit of $30,000 and you're not using them, close two and drop the limit on the third to $5,000. Your score might dip slightly in the short term because you've reduced your available credit, but your borrowing capacity improves and lenders see that you're managing your commitments.

Don't apply for new credit in the six months before you plan to apply for a home loan. No car finance, no store cards, no buy-now-pay-later accounts. Every enquiry chips away at your score, and every new account adds to your liabilities. If you need a car, save and buy it outright or wait until after your home loan settles.

Get a copy of your credit file before you apply. You're entitled to a version from each of the three credit bureaus, Equifax, Experian, and Illion. Check for errors. If there's a default listed that you've paid, make sure it's marked as paid. If there's an account you don't recognise, dispute it. Errors happen more often than they should, and they can cost you an approval or a rate discount if you don't catch them.

How We Work Around Credit Issues in Mandurah

We see credit issues regularly, and most of them are fixable with the right lender and the right timing.

If your file has marks, we start by pulling your credit report and identifying what's dragging your score down. Then we map out which lenders will work with your situation as it stands and whether waiting three to six months would open up lower-rate options. Sometimes the answer is to apply now with a specialist lender, get into the property, and refinance in two years when your score has recovered. Other times, the answer is to wait, pay off a default, and apply with a mainstream lender in six months at a lower rate.

Mandurah buyers often ask whether they should fix their credit before applying or just apply and see what happens. The second approach wastes time and adds enquiries to your file. If you're declined, you've made your situation worse. If you're approved at a higher rate than you needed to pay, you're locked in unless you're willing to pay break costs on a fixed rate or cop another enquiry by refinancing within a year.

We also work with first home buyers who have thin credit files, meaning not much history at all. That's not the same as bad credit, but some lenders treat it similarly. A 25-year-old with no loans, no defaults, and no credit cards might assume they'll sail through an application. In reality, some lenders prefer to see a demonstrated history of managing credit. In those cases, we direct them to lenders who focus more on savings history and income stability than credit history.

Call one of our team or book an appointment at a time that works for you. We'll pull your file, walk through what's there, and map out the clearest path to approval at a rate that doesn't cost you more than it should.
