Pre-approval: what it is, what it is not, and how long it lasts

08/19/2026

Pre-approval is a lender saying “based on what we have seen, we would probably lend you about this much”. It is genuinely useful, and it is not a promise. Knowing exactly where that line sits is what stops people getting caught.

What it does cover

A proper pre-approval means the lender has assessed your income, expenses, debts and credit file and run them through its serviceability calculation. That is real work, and the number it produces is a realistic ceiling rather than a guess.

It lets you bid or negotiate knowing your limit, and it tells an agent you are a credible buyer rather than someone still wondering.

What still has to clear

  • The property. Pre-approval is about you, not the place. A valuation below contract price, or a property type the lender restricts — a small apartment, an unusual build — can still stop the loan.
  • Verification. Some pre-approvals are assessed against documents; others run largely on what you declared. Ask which yours is. A system-generated one carries much less weight than one an assessor has actually looked at.
  • Anything that changes. Switching jobs, taking on car finance or opening a credit card between pre-approval and settlement can undo it. Change nothing until you settle.

How long it lasts

Commonly around three months, sometimes six. It can usually be extended, though the lender will want current payslips and may reassess against any policy that has shifted meanwhile.

That expiry matters more than people expect in a long search. If you have been looking for five months, check the date before you bid.

Auctions are the sharp edge

At auction there is no cooling-off period and no finance clause. The hammer falls and you are contractually bound. If finance then fails, you lose the deposit and can be liable for more than that.

Bidding at auction without pre-approval is the riskiest thing an ordinary buyer can do, and it is entirely avoidable.

Does applying hurt my credit file?

A formal pre-approval creates an enquiry. One is unremarkable. Four in two months reads like someone being repeatedly declined, and lenders treat it that way.

That is the argument for checking policy before applying rather than trying your luck in several places — the aim is to get it right once.

Before you go looking

Work out the realistic number first, then get it confirmed. Walking into a pre-approval already knowing what the answer should be is how you avoid a surprise.
