What to do if a buyer gazunders you

What is gazundering?

Gazundering is when a buyer lowers an offer you have already accepted, usually right before exchange of contracts. It sits next to its opposite, gazumping, which is when a seller accepts a higher offer from a different buyer after a sale has already been agreed. Both are possible because, in England, Wales and Northern Ireland, a property sale is not legally binding until contracts are exchanged.

A gazunder usually lands late and on purpose. The buyer waits until you have packed boxes, booked a removal van and committed to your own onward purchase, then asks for a lower price. The timing is the pressure, built to make saying no feel more expensive than saying yes.

How common is gazundering?

Gazundering is not rare, but it is not the norm either. Research by the property firm Quick Move Now, published on 13 February 2025, found that around 19% of property sales saw a buyer try to renegotiate the price after it had been agreed. That is roughly one sale in five.

What happens after the attempt matters more than the attempt itself. The same research broke down how those renegotiations ended.

Read the middle two rows together. Among sellers who refused to drop their price, the sale still completed at the original figure in 28 cases out of every 34 that held firm. That is more than four in five.

Only 6% of gazundering attempts, close to 1% of all sales, ended in the sale collapsing after the seller said no. The common fear, that refusing always loses the deal, is not what the evidence shows.

Why is gazundering more likely in 2026?

Gazundering rises when buyers feel they hold the stronger hand. A buyer is far more willing to push for a cut when prices look soft and there are plenty of other homes to choose from. The May 2026 market gives buyers exactly that footing.

• The number of homes for sale is at its highest level for this time of year since 2015, according to Rightmove's House Price Index published on 18 May 2026, so buyers have more choice and less fear of missing out.
• Nearly a third of homes already on the market have had their asking price reduced, the same index found, which tells buyers that sellers are willing to move on price.
• Two-year fixed mortgage rates climbed from around 4.83% in early March 2026 to 5.75% by mid-May, which squeezes what buyers can afford and gives them a reason to ask for less.
• Average asking prices were 0.3% lower than a year earlier, so a buyer can reasonably argue the ground has shifted since they first made their offer.

None of this means a gazunder is coming for your sale. It means the conditions that encourage one are in place, so it is worth deciding your response before you need it.

What should you do if a buyer gazunders you?

If a buyer drops their offer, the worst move is an instant answer. Work through these steps instead.

1. 1. Do not respond straight away

   Acknowledge the message and say you will consider it. A reduction made under time pressure is meant to be answered under time pressure. Taking a day removes that advantage and signals you are not rattled.

2. 2. Ask for the reason in writing

   Ask the buyer, through your agent or solicitor, to put the reason for the lower offer in writing. A specific reason, such as a survey finding, can be checked. A vague reason often means the buyer is simply testing how firm you are.

3. 3. Check the reason against real evidence

   If the buyer cites a survey result, ask to see the relevant section of the report. If they claim the market has moved, look at what comparable homes nearby have actually sold for. Treat every claim as something to verify, not something to accept.

4. 4. Know your walk-away price

   Decide the lowest figure you will accept before you reply, based on your own numbers rather than the buyer's pressure. A sale proceeds calculator helps you see what a reduced price would leave you with once your mortgage, fees and onward purchase are accounted for.

5. 5. Weigh the cost of starting again

   Compare the proposed reduction against the real cost of losing this buyer: more time on the market, another round of viewings and the risk to your own onward purchase. Sometimes a small reduction is genuinely the cheaper outcome. Often it is not.

6. 6. Give a clear answer

   Reply plainly: accept, reject, or counter with a smaller figure. If you reject, say so calmly and restate the price you originally agreed. The research shows most sales held together when sellers did exactly that.

7. 7. If you do agree a cut, ask for something back

   If you accept a reduced price, attach a condition, such as an immediate exchange of contracts on a fixed date. That turns a loss into the one thing a gazunder cannot survive: a binding deal.

How can you reduce the risk before it happens?

You cannot make gazundering impossible while the law allows the price to change up to exchange. You can make your sale a far less tempting target.

• Price the home realistically from the first day. An asking price set to win the instruction rather than reflect the market invites a correction later, often dressed up as a gazunder.
• Be open about known faults before you accept an offer. A problem found in a survey is the most common honest reason a buyer reduces their offer.
• Consider a pre-listing survey. Paying for your own RICS Level 2 or Level 3 report before you market the home lets you fix or price in problems early and removes the buyer's strongest justification.
• Favour buyers in a strong position. A chain-free buyer with a mortgage agreed in principle has fewer reasons, and less room, to renegotiate.
• Push for a short, firm timeline to exchange. The longer the gap between offer and exchange, the more time a buyer has to get cold feet or find a reason to push.
• Choose an agent who manages the sale, not just the listing. Steady contact between offer and exchange keeps a buyer committed and catches wobbles early.

A gazunder is a test of nerve, not a verdict on your home. The seller who knows their walk-away price before the call comes is the seller who keeps control of it.

Is gazundering legal?

Yes, gazundering is legal. Exchange of contracts is the point at which a property sale becomes legally binding on both sides, and in England, Wales and Northern Ireland a buyer can lower their offer at any time before that point. It can feel unfair, and often it is, but it is not against the law.

Scotland works differently. There, the written offer and acceptance, known as the missives, become binding earlier in the process, which is why gazundering is far less common north of the border. For the rest of the UK, exchange of contracts is the line: everything before it can move, and everything after it cannot.

Staying in control of your own sale

Gazundering works on a single feeling: that the sale is no longer yours to direct. The answer is to make decisions from your own evidence and your own numbers, on your own timeline, rather than from the pressure inside a phone call.

That principle reaches further back than one tense moment near exchange. It is also why ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents, so a seller can compare, decide and stay in control from the very first valuation, long before any buyer is on the scene. Selling starts with your decision, not someone else's.
