Auction vs private treaty: what buyers need to know

Auction and private treaty are two different games for buyers. Auction is fast, transparent and unconditional. Private treaty is slower, negotiable and gives you a cooling-off period. Which one suits you depends on the property and your risk tolerance.

How does buying at auction work?

You research and inspect a property that has an auction date set, usually 3 to 4 weeks out. You do all your due diligence (finance approval, building and pest, contract review) before the day. On auction day you register, bid in an open competitive process, and if you win, you sign an unconditional contract and pay a deposit on the spot. No cooling off. See How to bid at auction for the full mechanics.

How does buying by private treaty work?

The property is listed with an asking price or price guide. You inspect, make a written offer through the agent (or online via /offer), and negotiate. Once a price and terms are agreed, you sign a contract that can include conditions like finance, building and pest, and sale of another property. You then have a 5 business day cooling-off period unless you waive it.

Which is better for buyers?

Neither is objectively better. It depends on you and the property.

Auction favours you if

- You have your finance, inspections and legal review all done. - You want to see exactly who else is buying and at what price. - You are confident enough to stop at your ceiling. - The property is in high demand and would probably sell above the guide anyway.

Private treaty favours you if

- Your finance is still being worked through. - You want conditions like building and pest, or a longer settlement. - The property has been listed for a while and momentum has cooled. - You want time to think overnight after the first offer.

Can I buy an auction property before the auction?

Sometimes. Some vendors accept pre-auction offers if the number is strong enough. If you go this route the contract is still usually unconditional, because the vendor gives up their auction strategy to accept you. Always ask the agent early rather than the week before.

How does price transparency compare?

Auction is more transparent for buyers because you see every other bid live. Private treaty is more private, and price guides in Queensland can be conservative or aspirational depending on the agent. If price transparency matters to you, auction is friendlier. If you prefer to negotiate quietly, private treaty is friendlier.

What about cooling off?

Private treaty gives you 5 business days cooling off (you can waive by signing a waiver). Auction gives you nothing. Full detail in Cooling-off periods in Queensland.
