With that kind of money you could buy a house outright in several parts of the UK, all of Canada, France, etc etc. Why buy in the crappy UK when you've got that kind of money?
You mention later someone renting out a tatty 3 bed ex-council semi for £850 a month. Wonder why the people don't rent here in Berkshire. I pay £1000 a month for a 4 bed, 3 bath, detached on the best estate in the area.
