Key Takeaway

Home loan pre-approval (also called conditional approval) in Australia gives you an indicative borrowing limit before you start house hunting. Lenders assess your income, expenses, credit file, employment stability, deposit size, and the loan-to-value ratio (LVR) to determine serviceability. Pre-approval typically lasts 90 days (three months), though some lenders offer up to six months, and it remains subject to final property valuation and verification when you make an offer.

What Pre-Approval Is

Pre-approval is a conditional commitment from a lender stating how much they are willing to lend you, based on the financial information you provide before you find a property. According to ASIC MoneySmart, pre-approval helps you understand your budget and shows sellers you are a serious buyer. It is not a guarantee: the lender still conducts a full assessment once you choose a property, including an independent valuation and final document verification.

Pre-approval differs from pre-qualification, which is an informal estimate based on minimal information and carries no commitment from the lender.

What Lenders Check

Australian lenders run a comprehensive serviceability assessment during pre-approval, evaluating your ability to service the loan under current conditions and potential rate rises. The core checks include:

Income and Employment: Lenders verify your gross income from employment, self-employment, investment returns, or other sources. They typically require recent payslips (two to three months), tax returns (two years for self-employed borrowers), and an employment letter confirming your role and tenure. Casual or contract workers may need longer employment history.

Expenses and Liabilities: Your monthly living costs, existing debts (credit cards, car loans, personal loans, HECS-HELP), and financial commitments are assessed. Lenders use either your declared expenses or a benchmark (the Household Expenditure Measure, set by APRA) to calculate your surplus income after obligations.

Credit File: The lender runs a credit check through a credit reporting body (Equifax, Experian, or illion) to review your repayment history, defaults, court judgments, and credit enquiries. Multiple recent enquiries or a history of missed payments can reduce your borrowing capacity or lead to rejection.

Deposit and LVR: You must demonstrate genuine savings or a deposit (typically 5 to 20 per cent of the property value). Lenders calculate the loan-to-value ratio: if you borrow more than 80 per cent of the property value, you will usually pay lenders mortgage insurance (LMI), which protects the lender and adds to your upfront or ongoing costs.

Serviceability Buffer: As covered in foundational lending texts such as Principles of Finance, lenders stress-test your ability to repay by adding a buffer (typically 2.5 to 3 percentage points above the advertised rate) to ensure you can still afford repayments if interest rates rise.

How Long Pre-Approval Lasts

Pre-approval is typically valid for 90 days (three months) from the date of issue. Some lenders extend this to 120 or 180 days, depending on the product and your profile. The validity period gives you time to search for a property, make an offer, and proceed to unconditional approval.

Pre-approval expires if you do not find a property within the validity window, or if your financial circumstances change (new debt, job loss, reduced income). If your pre-approval lapses, you will need to reapply, and the lender will reassess your serviceability and credit file.

Once you make an offer and the contract goes unconditional, the lender conducts a formal valuation of the property and re-verifies your documents. If the valuation comes in below the purchase price, or your financial situation has deteriorated, the lender may reduce the approved amount or withdraw the offer.

Next Steps

Before applying for pre-approval, gather your payslips, tax returns, bank statements (three to six months), proof of deposit, and details of existing liabilities. Compare pre-approval terms across lenders, as validity periods, serviceability criteria, and LMI thresholds vary. Consider consulting a licensed mortgage broker for personalised guidance and access to a wider panel of lenders.
