Pre-approval: what it does and doesn't mean
Conditional approval vs. full approval vs. settlement, credit checks, expiry, and why pre-approval is not a guarantee of settlement — plus documents and the auction risk.
Key points
- Pre-approval, full approval and settlement are three different stages — pre-approval assesses you, full approval also assesses the specific property.
- A lender may perform updated credit or document checks before full approval — whether they repeat checks depends on the lender, not a universal rule.
- Pre-approvals expire, commonly somewhere in the 3-6 month range — check the exact date on your own letter.
- A pre-approved amount is a lender's ceiling, not your personal safe budget.
- Auction and cooling-off rules vary by state — don't rely on one national rule when bidding.
What pre-approval is — and isn't
Pre-approval (sometimes called "conditional approval" or "approval in principle") is a lender's indication that they're likely to lend you a certain amount, based on the information and documents you've provided so far. It is not a guarantee of final approval or settlement, and it isn't the same thing as full unconditional approval — the table below shows how they differ.
| Stage | What's been assessed | What can still change |
|---|---|---|
| Pre-approval | Your income, expenses and debts, based on documents provided so far | The specific property, your circumstances since, and final credit checks |
| Full (unconditional) approval | The lender's valuation of your specific property, plus a final check that nothing material has changed | Settlement itself — funds still need to be released |
| Settlement | Everything — loan documents signed, funds transferred | Nothing — this is the binding outcome |
Between pre-approval and full approval, a lender may perform updated credit, document or financial checks — whether they repeat checks depends on the lender and what was already verified, so don't assume either that nothing further will be checked or that everything already has been. Ask what was actually verified for your pre-approval and what remains conditional. Pre-approvals also expire — commonly somewhere in the range of 3 to 6 months depending on the lender (Australian Securities and Investments Commission (Moneysmart), verified 18 Aug 2026) — so always check the specific expiry date on your own letter rather than assuming a standard period.
Decision rule
Your pre-approved amount is a lender's ceiling, not a purchase-price target or your personal safe budget — see safe budget vs. borrowing capacity for how to set the number you should actually spend.
The pre-approval to settlement timeline
Initial enquiry → document submission → conditional pre-approval → property selected → lender valuation and property checks → formal (unconditional) approval → loan documents signed → settlement. Each arrow is a point where something can change the outcome — most commonly, a lender's valuation coming in below the contract price, or a change in the buyer's financial position between pre-approval and formal approval.
Common mistake: bidding at auction based only on pre-approval without confirming its expiry date and completing your own property due diligence first. Auction, cooling-off and contract-formation rules vary by state and territory — check the rules that actually apply where you're buying (in Victoria, see before-auction due diligence) rather than assuming one national rule.
Preparing your documents
Typical document categories: identity, income (payslips, tax returns for self-employed applicants), employment confirmation, savings and asset statements, details of existing debts (credit cards, personal loans, buy-now-pay-later), living-expense information, evidence of deposit source (including a gift letter if relevant), and any government-programme documentation. Self-employed applicants and those with variable income typically need more extensive documentation — ask your lender or broker early what they'll require.
Before you apply
Decide whether you'll go direct to a lender or work with a mortgage broker, and check your own credit report for errors before a lender sees it. A formal pre-approval application can itself create a recorded credit enquiry, so submitting several applications with different lenders just to compare isn't free of consequence — compare and shortlist first using comparing home loans, then apply once you've chosen.
