The house isnt nice, however for all of the posters saying you could get double the size for half the price - yes, well you could but anyone who has brought in London over the years has made tons of money on property in general. The house in the middle of nowhere will not go up in value as quickly as a house in London.
My DM has a very small 2 bed house in West London. It has gone up considerably since she brought 25 years ago. Its her only property and of course prices could crash etc etc. But somehow I dont think so.
