I know a house is worth what someone is willing to pay but here is one ex local authority house that has just come on the market in an area I am familiar with. 2 bedrooms, 900 square feet of actual living space, (although they're trying to flog it as 1100 or even 1400) which is on a par with the price of LA mansions (in terms of price per square foot) and not hugely far off New York real estate. Seems bonkers. And it hasn't even been renovated!
Admittedly it is a very nice road in a fashionable part of London and the road also has some lovely Victorian double fronted properties which can sell at over £3m. But I doubt any council tenant would be able to buy that house now.
