Because housing is a necessity, people are willing to pay high prices for it. Bidding wars can therefore persist even when relative supply grows, so long as credit markets enable them.
Right, that's why I see rural houses literally falling over because nobody wants to live in them. /s
Supply and demand applies to food. It definitely applies to housing.
The central argument of this is that because the number of houses per adult is the same as 1989, the housing supply is fine. And then they have the audacity to claim other people are cherry-picking. No mention of average household size being different now, even just considering adults (nor mention of urbanisation). There's little effort to support their own theory with numbers, either.
Not to mention, that very same graph has a noticeable dip right in the recent years where it's become an issue. They've just scaled the graph so it's not emphasised. 1989 was the last time it was so low.
