We're watching this thread developing at the Channel 4 4homes forum. Somebody had an offer accepted, now she's losing a bidding war. The house had been on the market for over year. Somebody else has been trying to sell their mother-in-law's gaff for 18 months, now a buyer wants to gazump at £5,000 over asking price. Somebody else reports being gazumped many thousands over asking price. What's going on? It's only a handful of people, but if it's proportional... Are these the renters who've been sitting the market out, waiting for a crash, now returning en masse and in a panic? Why not send us your gazumping stories, so we can see if a picture's emerging.
