Here's a mistake I see all the time: someone finds the perfect place, gets excited, then scrambles to sort finance — and either misses out or overcommits. Pre-approval flips that around. It tells you what you can borrow before you start looking, so you shop with confidence and bid without fear. Here's how it works.
What pre-approval actually is
Pre-approval (also called conditional approval) is a lender saying: "based on your income, deposit and credit, we'd be prepared to lend you up to roughly $X" — subject to a few conditions and a valuation once you find a place. It's not the final loan, but it's a serious, evidence-based green light.
Why it matters
- You know your real budget — no guessing, no heartbreak over places you can't reach.
- You can bid at auction — auctions are unconditional, so you need finance lined up first.
- You're taken seriously — agents and vendors treat a pre-approved buyer as a real one.
- You move fast — in a hot market, being ready can be the difference between winning and missing out.
Pre-approval turns "I think I can afford this" into "I know I can" — and that confidence changes how you buy.
How long it lasts
Most pre-approvals are good for about 90 days. If you haven't found the right place by then, it can usually be refreshed with updated documents. So the ideal time to get it is when you're genuinely ready to start inspecting — not months ahead.
Will it hurt my credit score?
A formal pre-approval typically involves a credit enquiry, and applying for several in a short window can look messy to lenders. This is exactly where a broker earns their keep: I match you to one suitable lender first, so you ideally carry a single enquiry — not five from shopping around yourself.
Pre-approval vs unconditional — the quick version
Pre-approval: "we'd likely lend you up to $X" — you bid with this.
Unconditional: property valued, file signed off — you settle with this.
One honest caution
Pre-approval is a strong indication, not a guarantee. The final loan still depends on the property valuing up and your situation staying the same — so unless I advise otherwise, you keep a finance condition on your offer. Get the structure right and pre-approval becomes a genuine advantage, not a false sense of security. You can estimate your numbers first on the borrowing power calculator.
