Offer Accepted on a NSW Home, but Another Buyer Appears: Can the Seller Still Change Their Mind Before Exchange?

In an ordinary NSW private-treaty property sale, an accepted offer does not usually prevent the seller from considering another buyer before contracts are exchanged. NSW Government guidance identifies exchange, rather than offer acceptance, as the point at which buyer and seller normally become legally bound. For Sydney buyers and vendors, the practical risk sits in the gap between agreeing on price and actually completing exchange.

A Sydney buyer can hear the words “your offer has been accepted” on Monday afternoon, arrange a building inspection that evening and have a conveyancer working through the contract on Tuesday morning.

By Tuesday afternoon, another purchaser may have appeared.

That second buyer might offer more money. They might offer the same amount but be ready to exchange immediately. They might accept the vendor's preferred settlement period, have the deposit available and request fewer amendments to the contract.

The first buyer may understandably feel that the transaction has already been agreed. Legally and operationally, however, the critical milestone in a conventional NSW private sale is usually still ahead.

NSW Government guidance on making an offer states that a seller may negotiate with other buyers before exchange and specifically recognises the situation commonly described as gazumping. The same guidance says vendors are not generally compelled to sell to a particular prospective purchaser before contracts have been exchanged.

The Accepted Offer and the Binding Transaction Are Two Different Events

The phrase “offer accepted” carries enormous commercial weight, but it should not be confused with confirmation that the property has been legally secured.

In a standard NSW private-treaty transaction, several pieces may still be moving after the price has been accepted:

• The purchaser's solicitor or conveyancer may still be reviewing the contract.
• Special conditions may still be under negotiation.
• The settlement period may not yet be agreed.
• The purchaser may still be arranging the exchange deposit.
• Building, pest or strata investigations may still be underway.
• A cooling-off waiver may be under discussion.
• The purchaser may not yet have signed their final contract.
• The parties may simply not have authorised exchange.

NSW Government guidance on contracts and deposits describes the agreement before exchange as usually not binding and states that both purchaser and vendor may generally change their minds up to that point.

This distinction also explains why Elyment's analysis of what a 0.25% deposit actually means before and at exchange stresses that transferring money alone does not necessarily confirm that a binding sale has been created.

When Buyer Two Appears, the Agent Cannot Simply Ignore the Offer

A competing offer creates obligations for the selling agent as well as a commercial decision for the vendor.

Under the Property and Stock Agents Regulation 2022, an agent acting for a vendor must generally inform the vendor of offers received as soon as practicable up to exchange, unless the vendor has provided written instructions to the contrary. The regulation contains a separate regime for auction bidding.

That means the appearance of another genuine purchaser is not necessarily an agent attempting to reopen a finished negotiation. Until exchange occurs, further offers can remain part of the vendor's decision environment.

NSW Government guidance also says an agent should notify a prospective purchaser who has paid an expression-of-interest deposit when a subsequent offer is made and advises that purchaser that further offers can be made before exchange.

The Seller Is Not Required to Choose the Highest Number

Once two purchasers are competing, price becomes only one component of the vendor's decision.

A sophisticated seller should be comparing the probability and quality of completion, not simply the number at the top of an email.

Purchase price

• Why it can matter to the seller: The obvious headline value, but not the only commercial consideration.

Exchange readiness

• Why it can matter to the seller: A purchaser able to sign and exchange promptly may provide substantially greater certainty.

Cooling-off position

• Why it can matter to the seller: The proposed exchange structure affects how much purchaser uncertainty remains after exchange.

Deposit readiness

• Why it can matter to the seller: Delays arranging the agreed deposit can delay the transaction-control point.

Settlement period

• Why it can matter to the seller: The vendor may need a particular date for relocation, mortgage discharge or another purchase.

Contract amendments

• Why it can matter to the seller: Extensive requested changes can create additional negotiation and execution risk.

Finance position

• Why it can matter to the seller: A buyer's financing circumstances can influence perceived transaction certainty, although the legal effect depends on the contract itself.

Property conditions

• Why it can matter to the seller: Requests concerning inspections, inclusions, access or other matters can materially alter the deal.

NSW Government guidance expressly notes that a vendor does not necessarily have to accept the highest offer. A lower offer can be preferred where the overall terms are more attractive.

A Sydney Example: $20,000 More Is Not Automatically the Better Transaction

Consider a hypothetical private sale of a Sydney apartment.

Buyer A has an accepted offer of $1.80 million. Their conveyancer is reviewing the contract, several amendments have been requested and the buyer wants additional time before exchange while finance and strata matters are investigated.

Buyer B appears the next morning offering $1.82 million and says they can move immediately.

The vendor now has a choice, but the decision is not necessarily:

$1.82 million beats $1.80 million.

The vendor and their adviser should instead compare the entire proposed transaction.

Buyer B may still request substantial changes when their solicitor reviews the contract. Their lender may still create delay. Conversely, Buyer A may be only hours away from being ready to exchange.

Equally, a second purchaser offering slightly less could potentially be more attractive if their proposed settlement date solves an important timing problem for the vendor.

This is why pre-exchange competition is fundamentally an execution problem as well as a negotiation problem.

The Real Competitive Advantage Is Often Exchange Readiness

Sydney purchasers frequently focus on improving their bid when another buyer appears. Sometimes the more important improvement is reducing the time between commercial agreement and contractual commitment.

That can require several workstreams to converge quickly:

1. Contract review. The purchaser needs to understand the contract and identify material amendments.
2. Instructions. Negotiated changes must be clearly communicated between the purchaser's and vendor's representatives.
3. Deposit arrangements. The purchaser should know exactly what is required at exchange and how it will be paid.
4. Finance strategy. The purchaser should understand what is and is not confirmed by their lender before changing the contractual risk they are prepared to accept.
5. Inspection and strata decisions. Outstanding due diligence should be identified rather than assumed to be complete.
6. Cooling-off position. Any proposal to waive, reduce or alter cooling-off rights should be dealt with through appropriate legal advice.
7. Exchange authority. Signing a document and actually authorising exchange are not always the same operational step.

Elyment's guide to urgent NSW contract review when an agent wants an answer immediately examines this compressed decision environment in more detail.

Paying an Expression-of-Interest Deposit Does Not Lock Out Every Other Buyer

One of the most persistent sources of confusion occurs when money has already changed hands.

A buyer may have paid an expression-of-interest amount and understandably assume that the property has now been secured.

That assumption can be wrong.

NSW rules distinguish a pre-exchange expression-of-interest deposit from the contractual deposit arrangements associated with exchange. Government guidance states that an expression-of-interest payment does not itself oblige the vendor to sell the property to that purchaser.

If another person ultimately enters into the contract, the expression-of-interest deposit is required to be refunded in accordance with the applicable rules.

For buyers, the practical question should therefore never be merely: “Has the deposit been paid?”

It should be:

“Have contracts actually exchanged, and has that exchange been confirmed?”

What Gazumping Actually Means in This Sequence

NSW Government describes gazumping as the situation where an agent or seller accepts a purchaser's offer at an agreed price but the property is ultimately sold to someone else, commonly following a higher subsequent offer.

The word often suggests misconduct, but it is important to separate the buyer's understandable frustration from the actual transaction stage.

Before exchange, the first buyer may already have incurred:

• Conveyancing or legal costs
• Building and pest inspection fees
• Strata report expenses
• Valuation or finance-related costs
• Time spent negotiating contract amendments
• Planning costs associated with moving or proposed renovations

Yet NSW Government guidance notes that a gazumped buyer is not generally entitled to recover those expenses from the agent or seller simply because another purchaser exchanged first.

That makes pre-exchange time financially meaningful even though the binding contract has not yet been created.

The Seller Also Needs a Disciplined Pre-Exchange Process

The ability to change direction before exchange does not mean a vendor should manage competing buyers casually.

Poor coordination can create contradictory instructions between the seller, agent and conveyancer, increase the risk of misunderstanding and turn a commercially useful second offer into unnecessary transaction disruption.

A stronger vendor workflow looks like this:

1. Record the complete offer. Price, proposed deposit, settlement timing and other material conditions should be understood.
2. Confirm the current contract status. Establish whether Buyer A has merely made an offer, signed a contract, delivered it to an adviser or actually authorised exchange.
3. Identify unresolved amendments. Determine what remains under negotiation with each prospective purchaser.
4. Compare transaction quality. Review price together with settlement, deposit, timing and requested contractual changes.
5. Give clear instructions. The vendor should make sure the agent and legal representative are working from the same decision.
6. Move decisively once a purchaser is selected. Leaving an accepted buyer in a prolonged undefined position can allow the entire competitive environment to change again.
7. Confirm exchange. Once signed contracts have actually been exchanged, the vendor's legal position changes materially.

Exchange Changes the Seller's Freedom Immediately

The central dividing line is important precisely because the seller's position becomes much more restrictive after it has been crossed.

NSW Government guidance states that signed contracts becoming exchanged binds both sides. Buyers of many residential properties may then have statutory cooling-off rights, subject to the transaction circumstances, but the seller does not receive an equivalent general cooling-off period.

A vendor who receives an even better offer after exchange therefore faces a fundamentally different problem from one who receives it five minutes before exchange.

Elyment's separate analysis, Can a Seller Pull Out After Exchange in NSW? What Happens Once Both Parties Sign?, examines that post-exchange position.

Do Not Treat a Cooling-Off Period as the Seller's Opportunity to Keep Shopping the Property

Another common misunderstanding is that because a residential purchaser may have a cooling-off period after exchange, the seller somehow remains free during the same period.

That is not the ordinary NSW position.

NSW property-agent guidance states that sellers do not receive a corresponding cooling-off period after exchange. The purchaser's statutory right, where applicable, does not create a matching vendor right to abandon the transaction because another buyer has offered more.

Buyers wanting to understand the post-exchange investigation window can review Elyment's guide to the NSW residential cooling-off period.

Auction Transactions Need to Be Separated From the Private-Treaty Scenario

The accepted-offer scenario discussed in this article is primarily a private-treaty problem.

Auctions operate differently. Once the reserve is met and the auctioneer accepts the successful bid at the fall of the hammer, the transaction enters a much more immediate commitment process. Standard residential cooling-off rights also do not apply to purchases made at auction, or in specified circumstances where contracts exchange on the same day after a property is passed in.

Buyers and vendors should therefore avoid applying ordinary pre-exchange private-sale assumptions to an auction transaction.

For Sydney Strata Property, Speed Can Collide With Due Diligence

The pressure becomes particularly acute in Sydney's apartment market.

A purchaser may be capable of signing a contract within hours while still waiting for detailed information about the building.

That information may concern:

• Special levies
• Capital works
• Major building defects
• Insurance
• Renovation by-laws
• Hard-flooring and acoustic requirements
• Building access arrangements
• Planned remedial works

Another buyer appearing does not make those questions disappear. It changes the time available for the purchaser to decide how much unresolved risk they are willing to carry into exchange.

This is where conveyancing and future project planning intersect. A buyer hoping to commence flooring removal, concrete preparation or renovation immediately after settlement may need to understand strata approvals and building logistics long before the keys are released.

The Pre-Exchange Window Is a Transaction-Control Problem

The central question is often framed too narrowly:

Can the seller accept another offer?

In an ordinary NSW private sale before exchange, generally yes.

The more useful commercial question is:

What still has to happen before either buyer can turn an accepted proposal into an exchanged contract?

That answer may depend on contract amendments, legal instructions, finance readiness, inspections, deposit arrangements, settlement requirements and the speed with which every participant can complete their part of the transaction.

Clarify the Transaction Before Exchange Becomes the Deadline

Review contract timing, competing-offer risks, conveyancing requirements, settlement dependencies, compliance considerations and post-settlement project planning before the transaction becomes binding.

Request a Project Review

The Bottom Line

An accepted offer on a NSW home is commercially important, but it does not ordinarily give the purchaser the same certainty as exchanged contracts.

Before exchange, another buyer can appear, the selling agent may be required to put that offer to the vendor and the vendor can generally reconsider which transaction they prefer.

Once exchange takes place, the seller's position changes sharply.

For Sydney buyers, the lesson is not simply to bid higher. It is to understand what remains between acceptance and exchange and to remove avoidable delays without abandoning appropriate due diligence.

For vendors, the lesson is equally operational. Compare the complete transaction, give clear instructions and make sure the agent and conveyancer are working towards the same exchange outcome.

The decisive moment is not when someone says “offer accepted”. It is when the transaction is actually exchanged.
