Auction finance: everything happens before the day

What the fall of the hammer does

When the auctioneer accepts your bid you sign the contract on the spot and the sale is binding immediately. There is no subject-to-finance clause, no building and pest condition, no valuation condition and no period in which you can reconsider. Every protection that exists in a normal private treaty purchase has to be dealt with before you raise your hand, because afterwards there is nothing left to negotiate.

This is why auction and private treaty are genuinely different transactions rather than two ways of doing the same one. In a private treaty purchase you can make an offer, then investigate. At auction you must investigate, then commit. Buyers who lose money at auction almost always lost it in the fortnight before, not on the day.

The cooling-off period you do not get

Cooling-off rights are set state by state and every one of them excludes auction purchases. New South Wales gives five business days on a private treaty sale but none where the property sells at auction. Victoria allows three clear business days on a private sale, and specifically removes it for a sale at public auction and for a sale within three clear business days before or after one. Queensland’s five-business-day period does not apply to a property bought at auction either.

The Victorian carve-out is the one that surprises people most. Signing a contract two days before the scheduled auction, or two days after the property passed in, can leave you in exactly the same position as bidding on the day, with no cooling-off. If you are doing a deal around an auction date rather than at the auction, ask your conveyancer specifically whether cooling-off applies before you sign anything.

The pre-auction work list

Contract and vendor disclosure statement reviewed by your solicitor or conveyancer, including special conditions, the settlement period, inclusions, and anything about easements, owners corporation liabilities or outstanding notices. Building and pest inspection completed, or a strata report for an apartment, because these cannot become conditions of an auction contract. Bidder registration with the identification each state requires.

On the finance side: a formal pre-approval that has actually been to a credit assessor rather than a calculator output, a clear ceiling expressed in dollars with duty and costs already deducted, and — where the lender offers it — an upfront valuation on that specific property. Several lenders will value a property before auction, which converts the single largest unknown into a known number for the price of a valuation fee. On a private treaty purchase it is useful; on an auction purchase it is the difference between a calculated risk and a guess.

Also confirm the settlement period before the auction rather than assuming it. Auction contracts are usually the vendor’s standard form with a set settlement date, and while agents will often accommodate a request made in advance, nothing can be changed once the contract is signed. If you need 60 days rather than 30, that conversation happens in the week before.

The deposit: amount, timing and method

The standard deposit is 10 per cent of the purchase price, payable on the fall of the hammer. Some vendors will agree to 5 per cent if asked in advance and it is recorded in the contract, but this is a concession negotiated before the auction, not a request you can make while holding the pen. Know the dollar figure at your ceiling price, not the percentage, and have the funds cleared and available in a transaction account days beforehand rather than sitting in a term deposit or a share portfolio.

Confirm with the agency how they will accept it — bank cheque, EFT to the trust account, or a deposit bond if the vendor has agreed to one — and check any payment limits your bank applies to a single transfer, which are frequently lower than a 10 per cent deposit on a capital-city house.

One warning that has nothing to do with lending. Real estate trust account details are a standard target for payment redirection fraud, where an emailed invoice or account change is intercepted and altered. Verify the account details verbally by calling the agency on a number you have sourced independently, never on a number or link in the email itself, and confirm receipt after you transfer. Money paid to a fraudulent account is very rarely recovered and does not discharge your obligation to the vendor.

Where pre-approval stops

A formal pre-approval says a credit assessor has reviewed your income, liabilities and expenses and is satisfied you can service a loan of that size. It does not say the lender has accepted the property you just bought as security. The valuation, the valuer’s risk ratings, the property type and the postcode are all assessed after you win, and a shortfall between the price and the valuation is funded by you in cash because the lender lends against the lower figure.

Pre-approvals are also conditional in ways that are easy to forget while bidding. They expire, usually at 90 days. They assume nothing has changed — a new car loan, a probation period, a change to a bonus structure or an increase in a credit card limit can all undo one. They frequently carry conditions that have not been satisfied yet. Reconfirm the pre-approval is current and unchanged in the week of the auction rather than relying on a letter issued three months ago.

A softer market changes the tactics, not the rules

With national values down for a fifth consecutive month in August 2026 and turnover well below a year earlier, more properties are passing in and vendors are more willing to deal. That opens two routes that barely worked in a hot market: a pre-auction offer, which if accepted can be made subject to finance because you are no longer buying at auction, and negotiating on a property that passed in, where the highest bidder usually gets first right to bargain with the vendor.

Both routes convert an unconditional purchase into a conditional one, which is a materially better position for a borrower carrying valuation risk. The trade is that you forgo the chance that the property sells cheaply on the day. In current conditions that trade is worth putting on the table more often than buyers assume, and it costs nothing to have your agent ask whether the vendor will consider a prior offer.

What has not changed is the discipline. A soft market does not make an unconditional contract safer, and the buyer who bids past their ceiling because the room felt quiet has the same problem as the buyer who did it because the room felt frantic.

What a broker can and cannot do here

A broker can get the pre-approval to a credit assessor rather than a calculator, arrange an upfront valuation where the lender allows it, tell you which lenders will accept that property type and postcode, and make sure your ceiling is expressed net of duty, LMI and settlement costs. What no broker can do is guarantee an approval, guarantee a valuation figure, or promise a settlement date, because those are lender decisions made after verification.

Azure Home Loans would rather do this work three weeks before an auction than three days after one, when the options have narrowed to finding cash.
