Two out of every three current buyers and sellers have experienced a previous fall-through in the past 12 months, research claims.

A survey of 574 users by conveyancing comparison website reallymoving.com found that buyers and sellers changing their minds was behind almost a third (29%) of all property transactions that fall through before exchange.

The findings reveal support for the Government’s proposed reservation agreements, which are likely to be trialled in early 2020, with 67% of buyers and sellers believing they would have benefited from the agreements.

Other reasons for a transaction collapsing were survey issues (17%) and difficulties obtaining mortgage finance (15%).

Another 11% had issues in the chain, while 7% said they were gazumped and 8% reported getting gazundered.

Rob Houghton, chief executive of reallymoving, said: “The system for buying and selling property in England and Wales is fundamentally unfair, requiring both buyers and sellers to commit considerable sums of money to a process in which they are entirely unprotected.

“People are also forced to make life-changing decisions about moving to a new area, perhaps changing jobs, children’s schools and so on, while at any moment the other side can pull out of the deal without consequence.

“To save the millions of pounds wasted through collapsed deals every year and to foster renewed trust between buyers and sellers, change is urgently required.

“Reservation agreements, which would require both sides to part with a lump sum of cash at the point an offer is agreed, would undoubtedly prompt people to think hard about their commitment to the process, which can only be a good thing.

“The devil will be in the detail, however, and there will need to be clear guidelines outlining what exactly constitutes a genuine reason for withdrawing from a sale.”
