Wow. Thank you!
I think they bought the worst type of house, at the worst time, in the worst area.
New builds tend to drop, the market had topped out by then and Bradford is not an up- and-coming area (no offence meant to anyone who lives there). Prices will continue to fall. They bought with help to buy, too, I believe. They'd have been better off buying a good sized terrace in a decent area for half the price. Their house has a silly layout for a 5 bed executive home and it looks like it was interior designed during an episode of Changing Rooms in the mid-90's.
More Chris impulsiveness biting them on the bum.
