What Factors Affect Loan Approval During the Home Buying Process

Jan 13 2026

Buying a home is exciting, but the loan approval step can feel like a black box. Lenders weigh a mix of numbers, policies, and risk checks to decide if your application stacks up. Knowing these factors ahead of time helps you prepare and spot any weak links before you apply.

How Lenders Judge Your Capacity to Repay

Lenders test your repayments at a higher rate than the one on the page. They want to see if you can still meet repayments when rates rise, or when bills and living costs shift. This helps them price risk and protect both you and the loan book.

A global news outlet reported that Australia’s prudential regulator expects banks to check if borrowers can repay at least 3 percentage points above the current home loan rate. That single test can shrink your maximum borrowing power if your budget is already tight. It means even small debts or a higher credit card limit can push you over the line in the calculator.

Income, Employment, and Stability

Lenders look for consistency in your payslips, regular hours, and low variability in bonus or overtime. If you’re self-employed, they’ll want evidence that profits are steady across years.

You might compare different lenders, products, and strategies with advice from Logan home loan specialists to match how your income is structured. A specialist can explain how probation periods, multiple jobs, or a new ABN affect your file.

If your earnings jump around, expect more questions. Contracts, letters from employers, or accountant notes can prove what is ongoing and what is one-off. The cleaner your story, the easier the approval.

Credit History and Existing Debts

Credit scores signal how you’ve handled money. Late payments, recent defaults, or too many new accounts raise flags fast. Lenders read your credit report for stability cues like account age and the mix of credit types.

Existing debts matter just as much as your score. Personal loans, car finance, and credit card limits all feed into your debt-to-income assessment. Even unused card limits count in the calculation, so reducing or closing old limits can lift your borrowing power.

If your credit is bruised, you can still map a path forward. Pay on time, avoid new credit, and give recent changes time to season. A short, factual cover letter can explain any one-off hiccup so the assessor does not have to guess.

Property Type, Location, and Valuation

Lenders prefer standard houses and units in established suburbs with strong resale demand. Unusual dwellings, tiny studio apartments, or properties in very small towns may face stricter rules or lower maximum LVRs.

Valuation shapes your approval. If the valuer comes in lower than the purchase price, your LVR jumps, and you may need a bigger deposit. That can trigger mortgage insurance or a policy decline, even when your income and credit look fine.

Common property flags to watch:

  • Very high strata fees or planned special levies
  • Buildings with known defects or cladding issues
  • Tiny internal areas or student-only restrictions
  • Rural or very limited local sales data

Policy Settings and Risk Buffers

Lender credit policy changes with the economic cycle. When risk rises, banks tighten rules on things like overtime income, living expenses, or maximum LVRs. Small policy shifts can move the goalposts for who qualifies and for how much.

Australia’s prudential regulator has written about the role of serviceability buffers that build resilience in loan portfolios. In practice, that means banks don’t rely on today’s low stress numbers alone. They model higher rates and tougher conditions to make sure future you can still pay the bills.

Market Trends and Timing

When demand is hot, turnarounds can slow, valuations get tight, and lenders scrutinize files to manage pipeline risk. Official statistics recently showed a lift in investor loan commitments across value and volume, pointing to a busier mortgage market.

Around the same time, industry data noted that secured credit demand rose, with mortgage demand higher year on year. Those trends can lengthen processing times and make it more important to submit a clean, well-evidenced file the first time.

If conditions cool, some policies may ease at the margins, but don’t bank on it. It’s smarter to shape your file so it succeeds in both busy and quiet periods. Solid savings, tidy expenses, and low consumer debts help in any market.

Living Expenses and Buffers

Your household budget is part of the decision. Lenders use benchmarks as a floor, then test your declared expenses against your statements. If your spending runs high, they use the higher figure.

Building a buffer in your own budget protects you from rate rises and unexpected costs after settlement. It makes the approval smoother since your numbers are more likely to pass the model’s stress tests.

A home loan approval is a chain of small wins. Get the numbers right, present a clear story, and work within the rules. When you do that, the process stops feeling like a mystery and becomes a method you can manage.
