Auction vs private treaty in NSW: choosing how to sell
Compare campaign timing, pricing, costs and contract considerations without assuming either sale method will produce a better price.
By Plan to Sell · Updated · General information
The short version
- Choose a method using property evidence and your constraints, not a promise of a higher price.
- An auction date is not a guaranteed sale or settlement date.
- NSW buyer cooling-off differs between private sales and auctions; ask your conveyancer before making decisions.
Start with the property and your constraints
Auction and private treaty are different ways to invite buyers to act. Neither is always better, and neither guarantees a particular price. Ask the agent to support a recommendation with relevant sales, likely buyer participation and the circumstances of your property. Explain your timing, budget and comfort with public bidding or ongoing negotiation.
Private treaty is often called private sale: a property is marketed with a price or pricing approach and offers are negotiated. An auction invites registered buyers to bid at a scheduled event, with a reserve and auction rules. Ask how each approach would work in practice, including early offers and a campaign that does not result in a sale.
Side-by-side: what changes for the seller
This comparison is a starting point for questions, not a prediction about your result. Campaign length, spending and agreed contract terms vary. Ask the agent and your solicitor or licensed conveyancer to explain the actual proposal.
| Factor | Auction | Private treaty |
|---|---|---|
| Timing | A scheduled auction creates a campaign milestone; sale is not guaranteed. | Negotiation can be more flexible; time to sale is uncertain. |
| Pricing | Discuss reserve, price representations and evidence with the agent. | Agree the advertised pricing approach and when to review it. |
| Buyer participation | Buyers need to understand bidding, registration and auction terms. | Buyers can make offers and propose terms for the seller to consider. |
| Costs | May include auctioneer and event-related campaign expenses. | Campaign expenses still apply; a longer campaign can add costs. |
| Conditions | Auction contract terms need review before bidding; cooling-off exceptions apply. | Offers may include negotiated conditions; applicable cooling-off must be understood. |
| If unsold | A passed-in property can move to negotiation or a revised campaign. | Review price, presentation, feedback and the campaign with the agent. |
| Pressure and flexibility | A public event can feel time-pressured; prepare decision limits beforehand. | Ongoing negotiation can allow flexibility but may involve repeated decisions. |
If you choose auction: agree the decision points
Ask how the reserve will be decided, who needs to approve it and when the conversation will happen. The reserve is not an independent valuation or a promise that bidding will reach it. Discuss how you will receive information during the event and who is authorised to make decisions.
Agree what happens if there is an offer before the auction, low bidding or no acceptable bid. A passed-in outcome is not the end of all options: you may negotiate or revise the campaign. But the costs, timing and legal position must be explained for that next step. Do not assume the auction date is the day you move out.
- What evidence supports an auction for this property and likely buyers?
- How will the reserve discussion be handled and documented?
- Who is the auctioneer, what is their charge and what does it cover?
- How are pre-auction offers presented and reviewed?
- What is the plan and additional budget if the property passes in?
If you choose private treaty: agree the review process
Clarify how the pricing approach will be explained to buyers and how you will review interest. Ask which feedback matters: suitable enquiries, inspection comments and actual offers can tell a different story from listing views. Pricing should be reviewed using evidence, not changed automatically after an arbitrary number of days.
Agree how quickly offers reach you and what details accompany them. A private treaty offer may propose finance, inspection or other conditions and a settlement date. Ask your adviser to explain their effect; you do not need to accept a condition simply because it is commonly requested.
- How will offers be recorded and compared fairly?
- When will we review pricing and campaign spending?
- What would justify changing the method rather than continuing the same plan?
- What costs remain payable if we stop or extend the campaign?
Cooling-off and contract questions in NSW
For established NSW homes sold privately, buyers generally have a five-business-day cooling-off period after exchange, subject to waiver or variation. The seller does not have an equivalent cooling-off period. There is no buyer cooling-off at auction or where exchange occurs the same day after the property passes in. Do not generalise these points to off-the-plan contracts.
This buyer-contract distinction is different from cooling-off under your agency agreement. Have your solicitor or licensed conveyancer explain both, along with deposit arrangements, conditions, inclusions and settlement. A buyer who is interested in the property is not automatically ready to accept the required terms.
Before you decide: request two complete proposals
Ask for an auction proposal and a private treaty proposal where practical, each with an itemised budget, GST treatment, timing, responsibilities and an unsold plan. Identify which items are optional and which are payable regardless of a sale. Compare the plans against your priorities rather than a promised selling-price difference.
Keep the written recommendation with your agent comparison notes. If the explanation does not connect to your property, ask more questions. Your choice can be informed and deliberate without pretending the market outcome is certain.
