What Is Gazundering – And How Can You avoid it?

Gazundering is when a buyer lowers their offer just before contracts are exchanged — even after the seller has already accepted the original price. Since property transactions in the UK aren’t legally binding until exchange, a buyer can change their offer at the last minute.

This puts sellers in a difficult position: accept the lower offer or risk losing the sale altogether, which is especially stressful if you're part of a property chain.

Why Does Gazundering Happen?

Gazundering typically occurs when buyers feel uncertain or when unexpected issues arise during the process. A recent UK survey revealed that 31% of sellers have experienced gazundering.

Here are some common reasons it happens:

• Survey issues: Problems like damp, structural faults, or subsidence uncovered in a survey may prompt buyers to revise their offer to account for repair costs.
• Changes in buyer’s finances: Mortgage offers may change or expire, or buyers may reassess what they can afford due to rising costs.
• Falling property prices: A dip in the housing market between the accepted offer and exchange may cause buyers to adjust their offer to match current valuations.
• Opportunistic tactics: Some buyers intentionally wait until the last minute to renegotiate, knowing the seller is under pressure to proceed.
•  Chain complications: If someone further up or down the chain is gazundered or pulls out, it can have a domino effect that pressures your buyer to lower their offers.

How to Respond to Gazundering

Under UK law, buyers are legally allowed to change their offer at any time before exchange. While it could be extremely frustrating, it is better to stay calm and weigh your options is key. Consider what’s in your best interest:

• Before exchange (most common): You’re not legally committed, so you can walk away, renegotiate, or accept the new offer.
• After exchange: Gazundering at this point is extremely rare and would likely breach the contract. If it happens, consult your solicitor immediately — the buyer could lose their deposit or face legal consequences.

Gazundering can be a stressful and disappointing part of the selling process, but being prepared and well-informed can help you handle it confidently.
