Mortgage pre-approval: what it actually means

Almost everyone tells you to "get pre-approval first," and fewer explain what it actually is or what it doesn't cover. This is where it fits in our first-home buyer guide for Victoria.

What pre-approval is

Pre-approval (or conditional approval) is a written indication from a lender that they're willing to lend up to a certain amount, subject to conditions, based on a review of your income, expenses, debts, and credit. It is not a loan. The actual loan only exists once a specific property is valued and the lender does its final checks. A typical letter gives you the maximum amount, an interest rate band, conditions, and an expiry (usually 3 to 6 months). It does not name a property or lock in your exact rate.

What it doesn't guarantee

This is the part buyers misread. Pre-approval can be cut or withdrawn if:

• The property doesn't value up. The lender values the property you choose; if it comes in under your price, they lend less and you cover the gap.
• Your circumstances change. A new job, fewer hours, new debt, or a credit change between pre-approval and final approval can shift the lender's position.
• The lender's policy changes. Criteria that fit in February might not in June, especially as rates tighten.
• It expires, after 3 to 6 months, usually renewable with a fresh income and expenses check.
• The property is hard to finance, such as apartments under 50 square metres or flood-prone land. Pre-approval doesn't cover property-specific issues.

Why it's still worth getting

Despite the caveats, pre-approval gives you a lender's view of your capacity (more accurate than your own guess), shortens the path to final approval, makes your offer more credible to agents, and clarifies what you need on top of the loan for the deposit, stamp duty, and costs. It also surfaces any credit or expense issues now, rather than the day before settlement.

It helps to know the three states. No approval: shopping on a guess. Pre-approval: a written indication, fine for most shopping, but it can change. Unconditional approval: the lender has approved a specific loan for a specific property, the only "yes, here are the funds" state. For auction buyers, unconditional approval is the goal, because the contract is binding at the hammer with no cooling-off period.

How to get it, and what lenders look at

You can go direct to one bank (simple and fast, but you won't know if another lender is better) or through a mortgage broker, who shops your application across lenders and handles the paperwork (a useful starting point for most first-timers, though brokers are paid commission by the lender). Either way you'll provide income evidence (payslips, tax returns, and more for the self-employed), expense evidence (a few months of bank and credit card statements, plus other debts), ID, and asset evidence. The lender stress-tests the repayments against your income to set your capacity.

A few things surprise buyers:

• Living expenses matter. Lenders use your actual spending or the Household Expenditure Measure benchmark, whichever is higher, based on recent statements. Free-spending months lower your capacity.
• Buy-now-pay-later counts as debt. Heavy Afterpay or Zip use reduces borrowing capacity.
• HECS-HELP reduces capacity, as a monthly obligation that scales with income.
• Multiple applications hurt your credit score. Each one is recorded, so use a broker or apply to one or two lenders at a time rather than five.

Timing and getting ready

Get pre-approval when you're seriously planning to buy: 12 months out means redoing it, and one week out is cutting it fine. Online approvals can take days; full ones with manual underwriting take one to three weeks. Before applying, check your credit report (free at illion or Equifax) for errors, gather your documents, and decide between a broker or going direct.

Pre-approval is the start of the borrowing process, not the end. Treat it as a guide, knowing the real test comes when you find a property and the lender does its final checks.
