This article is a year old and the figures have gone up since then:
http://www.bbc.co.uk/news/business-40044864Aggregate house prices are finally less bullish and we're seeing the value of houses drop in real terms in almost every region, especially in London.
By the time Brexit happens in December 2020 house prices will likely be at their lowest in real terms for decades. Interest rates might also be lowered to combat a sluggish economy, presenting a good opportunity for buyers.
I think the housing crisis will largely be negated in the short-medium term provided we don't have net migration of 300k+ a year, but long term it'll always be a problem because of the size of our island coupled with how many people want to live here.
