I got my house - in a very pricey part of London - for a really low price because it was filthy and hideously decorated. Plus the couple were going through a ghastly divorce and quite clearly had agreed to accept the first offer they got: they put the house on the market the week before Christmas, we saw it and put in a silly offer, they accepted - you only do that to stick two fingers up to your other half, surely? One of their kids greeted us by scrawling sexually explicit and racist graffiti all over her room.
I really love a bargain, but also like that however much of a tip my home looks, it will NEVER be as bad as it was.
