There's something of a divide in the UK, and definitely London, now between those who got sorted for housing before the boom (either by buying or by getting social housing when it was still possible to get it) and those who did not. We're in a very fucked situation now - if you didn't get yourself sorted then, there are only bad options available to you - stretch yourself for a mortgage in a place you don't even really want to live, or pay over the odds for a private, insecure place that you might be booted out of with two months' notice.
