How Does Home Loan Pre-Approval Actually Work?

Pre-approval (sometimes called conditional approval) is a lender's indication that they'll lend you up to a certain amount, subject to conditions being met most importantly, that the property itself passes their valuation and lending criteria once you've found one.

What actually gets assessed

A genuine pre-approval involves the lender reviewing your income, expenses, existing debts, credit history and deposit essentially the same serviceability assessment as a full application, minus a specific property to lend against. That's different from an instant online "borrowing estimate," which is a useful starting point but isn't a lender commitment.

What pre-approval gives you

• A real budget so you're inspecting and negotiating within a range you're actually approved for, not guessing.
• Negotiating strength sellers and agents take offers more seriously from a buyer who's pre-approved, particularly at auction.
• Time saved later much of the paperwork is already done, so once you find a property, the remaining steps to full approval are usually faster.

What it doesn't guarantee

Pre-approval is conditional final approval still depends on the specific property passing valuation, your financial position not changing materially, and the lender's final checks. If you take on new debt, change jobs, or your circumstances shift between pre-approval and settlement, the lender can reassess.

How long it typically lasts

Pre-approvals commonly last around 90 days, though this varies by lender. If you're taking longer than expected to find a property, it's worth checking in a lapsed pre-approval can usually be renewed, but it's better to know before you're mid-negotiation.

Getting it right the first time

Because pre-approval involves a real credit assessment, it's worth doing properly rather than applying to multiple lenders speculatively multiple credit enquiries in a short period can affect your credit file. Comparing lenders' policies first, then applying to the one that actually fits your situation, is a large part of what a broker does before you submit anything.
