Signing unconditional before finance is certain
Why going unconditional without formal approval is the largest avoidable risk in an Australian purchase, what the deposit exposure actually is, and why a falling market makes it worse.
The gap that catches people
Pre-approval is not approval. It is a lender’s indication based on information you supplied, usually subject to a valuation, to verification of what you stated, and to the lender’s policy at the time you formally apply. Formal approval comes after the lender has assessed the actual property and the actual documents.
Going unconditional means you are contractually bound to complete whether or not the lender ultimately funds you. Every year buyers do this on the strength of a pre-approval letter, and most of the time it works. The problem is the distribution of outcomes, not the average one: when it fails, it fails at the deposit.
What you are actually exposed to
If you cannot settle, the vendor can terminate and retain the deposit, commonly 10% of the purchase price. On a $800,000 purchase that is $80,000. The vendor may also pursue you for loss on resale if the property later sells for less, plus their costs.
That second exposure is the one buyers underestimate, and it is precisely the one a falling market activates. With values about 3.6% below the March 2026 peak after five consecutive monthly declines, a resale shortfall is no longer a theoretical tail risk.
Auctions remove the safety net
A property bought at auction is unconditional on the fall of the hammer in every Australian state. There is no cooling-off period and no subject-to-finance clause. This is the single most common route to the problem described on this page, and it is why auction finance is worth preparing differently from a private treaty purchase.
For private treaty, cooling-off rights exist in most states but are short, vary by jurisdiction, and usually cost a percentage of the price to exercise. They are a narrow escape hatch rather than a substitute for approval.
Valuation is the usual failure point
The most common reason finance falls over after pre-approval is a valuation below the contract price. The lender lends against its valuation, so a $780,000 valuation on an $820,000 contract leaves a $40,000 gap you must fund in cash on top of your deposit.
In a rising market this resolved itself often enough that buyers stopped worrying about it. In the current market, valuations coming in under contract price is the ordinary case rather than the exception, particularly for off-the-plan stock contracted at earlier prices. Ask what the fallback is before you need one.
How to close the gap
Where the contract allows it, a properly drafted finance clause with a realistic date is the protection. Where it does not — at auction, or where the vendor will not accept one — the answer is to do the assessment work before you bid rather than after: a lender that has seen your documents, a view on the specific property, and a clear number you will not exceed.
Azure Home Loans can prepare a file to that standard before an auction. This page is general information for Australian readers and not legal advice; contract terms, cooling-off rights and deposit consequences vary by state, so have your conveyancer or solicitor review the contract before you sign.

FAQ
What happens if I go unconditional and my loan is declined?
You remain contractually bound to complete. If you cannot, the vendor can terminate and keep your deposit, commonly 10% of the price, and may pursue you for any shortfall if the property resells for less plus their costs. This is the reason the pre-approval and formal-approval distinction matters.
Is a property bought at auction unconditional?
Yes, in every Australian state, from the fall of the hammer. There is no cooling-off period and you cannot make an auction purchase subject to finance. All the assessment work has to happen before you raise your hand, which is what makes auction purchases different from private treaty.
Does a cooling-off period protect me?
Only partially. Cooling-off rights apply to most private treaty purchases but not auctions, run for a short period that varies by state, and usually cost a percentage of the purchase price to exercise. Treat them as a narrow escape hatch rather than a substitute for approval.
What if the valuation comes in below the contract price?
The lender lends against its valuation, not your contract. A $780,000 valuation on an $820,000 contract leaves a $40,000 shortfall you must cover in cash on top of the deposit. With national values down about 3.6% from the March 2026 peak, this is currently common rather than unusual.
Can I make an offer subject to finance?
On a private treaty purchase, usually yes, and you should. Ask for a realistic date rather than the shortest one the agent suggests, because a clause that expires before the lender can reasonably decide offers little protection. At auction the option does not exist.
How long does formal approval take after pre-approval?
Commonly one to three weeks once the contract and valuation are in, though it varies by lender and by how quickly documents are supplied. The valuation is usually the longest step and the least predictable, which is why finance clause dates should allow for it rather than assume the best case.
