Few things sting like losing a house you thought was yours. Gazumping, where a seller accepts a higher offer after already agreeing to sell to you, is legal in England and Wales right up until contracts are exchanged. You cannot prevent it entirely, but you can make yourself the buyer a seller is reluctant to drop.
Why it happens
Until exchange, nothing is binding. If a better offer appears while your purchase crawls through searches and surveys, a seller is free to take it. Rising markets make gazumping more common, because new buyers keep arriving with deeper pockets while you wait on paperwork.
Move quickly and look organised
Speed is your best defence. The faster you reach exchange, the smaller the window for someone to outbid you. Have a mortgage agreed in principle before you offer, instruct a responsive solicitor the moment your offer is accepted, and respond to every request without delay. A buyer who is visibly ready is harder to abandon.
- Mortgage in principle ready shows the seller you can proceed
- A proactive solicitor who chases rather than waits
- Prompt replies to enquiries and document requests
Ask for the property to come off the market
Once your offer is accepted, ask the agent to mark the listing as sold subject to contract and stop conducting viewings. Sellers are not obliged to agree, but many will, especially if they sense you are committed and quick. It removes the temptation of a parade of rival buyers.
Consider insurance and goodwill
Some buyers take out home-buyer protection insurance to recover wasted legal and survey fees if a sale collapses through no fault of their own. It will not give you the house, but it softens the financial blow. Above all, keep relations warm; a seller who likes you is less likely to take the money and run.
