This really isn't true - the supply/demand issue with house prices is not the houses, but the availability of cheap credit to buy them with. Otherwise there would be no way that house prices in London could end up being 12 times the average wage in London. Actually they would be literally unaffordable if it wasn't for the bubble-economics ponzi scheme of ever-increasing prices funded on a sea of cheap credit.
It's come to an end now and prices will crash accordingly, personally I can't wait.
Long live the recession!
Anyway, £380,00 for a 2 bed flat in Brixton?? F***ing ridiculous. Buy now and lose a fortune!
