I think I must be missing something!? If it's a case of lots of people moving from cities and towns to more rural areas, surely there would then be more properties available in the towns so the prices there wouldn't rise? However prices are going up across the board.
Houses where I live are going instantly, even houses that would previously Sat on the market for a while. There also seems to be a real lack of rental properties too! I'm in the south West.
