How Lenders Assess Your Home Loan Application — And How to Get Approved

What Actually Happens When You Apply for a Home Loan

Most borrowers focus on the interest rate. Lenders focus on risk. Before a bank or non-bank lender approves your home loan, they run a detailed assessment of your financial position — not just what you earn, but how stable that income is, what you owe, what you spend, and whether you could still meet repayments if rates rose significantly.

Understanding this process gives you a real advantage. It tells you where the gaps in your application are, what to fix before you apply, and which lender is most likely to say yes to your situation.

How Lenders Assess Your Application

Income Verification

Lenders want to see stable, verifiable income. For PAYG employees, that typically means two recent payslips and the last two years of group certificates or tax returns. For self-employed borrowers, lenders generally require two years of personal and business tax returns, along with ATO notices of assessment.

Not all income is treated equally. Overtime, bonuses, and commission are often shaded — meaning lenders will only count a portion of it (commonly 50–80%) because it isn’t guaranteed. Rental income is typically assessed at 70–80% of the gross amount to account for vacancy and expenses. Casual and contract income may be accepted, but lenders will want to see a consistent history — usually at least 12 months in the same industry.

Employment Type and Stability

Permanent full-time employment is viewed most favourably. Casual, part-time, contract, and self-employed borrowers face more scrutiny. If you’ve recently changed jobs, lenders will assess whether you’re in the same field or have moved into a new industry. A probationary period can be a red flag — some lenders won’t approve applications until probation is complete.

Self-employed borrowers often find the process more complex. Lenders look at the net profit of the business after tax, not the gross revenue. If you’ve been legitimately minimising your taxable income, that can reduce your assessed borrowing capacity — even if your actual cash flow is strong.

Credit History

Your credit file is one of the first things a lender checks. It shows your repayment history on credit cards, personal loans, car loans, and any previous home loans. It also records defaults, court judgments, and credit enquiries.

A default — even a small one from a forgotten utility bill — can significantly impact your application. Multiple credit enquiries in a short period can also raise concerns, as it suggests you’ve been shopping around for credit aggressively. Under Australia’s comprehensive credit reporting (CCR) regime, lenders can now see 24 months of repayment history, not just negative events.

Existing Debts and Liabilities

Every liability you carry reduces your borrowing capacity. Lenders assess your existing debts — credit cards, personal loans, HECS-HELP debt, car finance, and buy-now-pay-later accounts — and factor in the repayments when calculating whether you can service a new home loan.

Importantly, credit card limits are assessed at the full limit, not the outstanding balance. A $20,000 credit card limit you never use still counts against you, because the lender must assume you could draw it down at any time.

Living Expenses

Since the Hayne Royal Commission, lenders have significantly tightened how they assess living expenses. You’ll be asked to declare your monthly expenses across categories including groceries, utilities, transport, insurance, childcare, and entertainment. Lenders cross-reference your declared expenses against the Household Expenditure Measure (HEM) benchmark and will use whichever figure is higher.

If your declared expenses look unrealistically low, expect the lender to apply HEM — which may be higher than what you actually spend. Accurate, honest expense declarations are in your interest.

Key Factors That Affect Your Borrowing Capacity

Loan-to-Value Ratio (LVR)

LVR is the ratio of your loan amount to the value of the property. A $600,000 loan on an $800,000 property gives you an LVR of 75%. Most lenders prefer an LVR of 80% or below. Above 80%, you’ll generally be required to pay Lenders Mortgage Insurance (LMI), which protects the lender — not you — in the event of default.

LMI can add tens of thousands of dollars to the cost of your loan. Some lenders offer LMI waivers for certain professions (doctors, lawyers, accountants) or for borrowers with strong financial profiles. A larger deposit doesn’t just reduce LMI — it also signals financial discipline to the lender.

Debt-to-Income Ratio

APRA has directed lenders to pay close attention to debt-to-income (DTI) ratios. A DTI above 6x is considered high risk — meaning if your total debts (including the proposed loan) exceed six times your gross annual income, many lenders will decline or significantly limit your application. Some lenders apply a lower internal threshold of 5x or 5.5x.

This is a hard constraint that no amount of good credit history can easily overcome. If your DTI is too high, the solution is either to reduce existing debt or increase income — there’s no shortcut.

The APRA Serviceability Buffer

Under APRA’s macroprudential guidelines, lenders must assess your ability to repay the loan at your actual interest rate plus a 3% buffer. If your loan rate is 6.5%, the lender tests your repayments at 9.5%. This buffer is designed to ensure borrowers can withstand rate rises without defaulting.

The buffer directly reduces how much you can borrow. It’s one of the most significant constraints on borrowing capacity in the current rate environment, and it applies across all lenders regulated by APRA.

Dependants and Financial Commitments

Every dependant — child, elderly parent, or other financial dependent — increases the lender’s estimate of your living expenses and reduces your assessed surplus income. Childcare costs, school fees, and family-related expenses all factor into the serviceability calculation. This doesn’t mean families can’t borrow — it means the numbers need to stack up with those costs included.

How to Strengthen Your Application Before You Apply

Reduce Your Liabilities

Pay down or close credit cards and personal loans before applying. Even if you have the cash to service the debt, eliminating the liability removes it from the lender’s assessment entirely. Closing a $15,000 credit card limit can meaningfully increase your borrowing capacity — sometimes by $60,000–$80,000 depending on the lender’s methodology.

Buy-now-pay-later accounts (Afterpay, Zip, Humm) are increasingly scrutinised. Close any you don’t need. They appear on your bank statements and some lenders treat them as indicators of cash flow stress.

Clean Up Your Credit File

Obtain a copy of your credit report from Equifax, Experian, or illion before you apply. Check for errors, outdated defaults, or listings that shouldn’t be there. Dispute anything inaccurate — credit reporting agencies are legally required to investigate and correct errors.

If you have legitimate defaults, address them. Paid defaults are viewed more favourably than unpaid ones. Some specialist lenders will consider applications with defaults, but you’ll pay a higher rate and face tighter conditions.

Avoid making multiple credit enquiries in the months before your application. Each enquiry is recorded and can signal credit-seeking behaviour to lenders.

Save a Genuine Deposit

Lenders distinguish between genuine savings and gifted funds. Genuine savings are funds you’ve accumulated over time — typically evidenced by three to six months of consistent savings history in your bank account. A gift from a family member may be accepted, but many lenders require a portion of the deposit to be genuine savings.

A larger deposit does more than reduce your LVR. It demonstrates financial discipline, reduces the lender’s risk, and may give you access to better rates and products. If you’re targeting an 80% LVR to avoid LMI, factor in stamp duty, legal fees, and other purchase costs — you’ll need more than just a 20% deposit.

Choose the Right Lender for Your Situation

Not all lenders assess applications the same way. The major banks apply conservative policies, particularly for self-employed borrowers, those with complex income structures, or applicants with credit blemishes. Non-bank lenders and specialist lenders often have more flexible credit policies — but typically at a higher rate.

A commercial finance broker with access to a broad lender panel can match your profile to the lender most likely to approve your application on the best available terms. This is particularly valuable if your situation doesn’t fit the standard mould — multiple income sources, recent self-employment, a prior default, or a non-standard property type.

The Bottom Line

Getting approved for a home loan in Australia isn’t just about having a good income. It’s about presenting a clean, well-structured application to the right lender at the right time. Understand how lenders assess risk, address the weaknesses in your financial profile before you apply, and work with a broker who knows which lenders will look favourably on your situation. That’s how serious borrowers get approved — and get the right deal.
