Gazumping - what it means and how to avoid it

Gazumping is when a seller accepts a higher offer from a different buyer after already accepting your offer, but before exchange of contracts. In England and Wales, a property sale is not legally binding until contracts are exchanged, which means the seller is free to accept a higher offer at any point before that. Gazumping can happen days, weeks, or even months after your offer was accepted, often after you have spent money on surveys, legal fees, and mortgage arrangements. It is one of the most frustrating aspects of buying property in England and Wales.

Yes, gazumping is legal in England and Wales because the sale is not legally binding until contracts are exchanged. The seller has no legal obligation to proceed with the original buyer until that point. Scotland has a different system where the sale becomes binding much earlier in the process, which effectively prevents gazumping. There have been calls to reform the system in England and Wales to make offers binding earlier, but no legislation has been passed to prevent gazumping.

Gazumping is more common in rising markets where there is strong competition for properties. Industry estimates suggest that between 1 in 20 and 1 in 10 property transactions are affected by gazumping in competitive markets. In slower markets, it is less common because sellers are grateful to have a buyer at all. Gazumping tends to increase when house prices are rising quickly and there are more buyers than sellers, creating conditions where multiple offers are made on the same property.

As a seller, you can avoid the complications of gazumping by selling to a cash buyer with no chain. This means the sale completes quickly (7 to 28 days) before any competing buyer has time to make an approach. The speed of a cash sale dramatically reduces the window in which gazumping can occur. You also avoid the ethical dilemma of whether to accept a higher offer after already shaking hands on a deal, and you avoid the risk of the first buyer walking away because they feel strung along.

Gazundering is the opposite of gazumping. It is when the buyer reduces their offer at the last minute, usually just before exchange of contracts, knowing the seller is committed and unlikely to walk away after months of waiting. Gazundering is particularly common in falling markets or when the buyer knows the seller is in a difficult position (divorce, financial pressure, chain-dependent). Selling to a cash buyer like HouseBought4Cash eliminates gazundering because we make a firm offer and do not reduce it unless the survey reveals a previously unknown issue.
