I suppose it depends on each individuals interpretation of a "crash".
It doesn't take a member of mensa to realise that property prices are vastly overpriced in the South of England, and that during a recession these prices will reduce.
If prices reduce to a such a level that it is more...
Like I said, just a correction in Brighton.
According to that website, £250k for a bog standard 3 bed house in Baden Road.
I know this area well, and despite the price reducing, this is still overpriced.
