yeah in NL for example they have a "shortfall" of a million houses, due to overly strict regulations scaring off developers. 40% of new builds need to be social housing, and we have the strictest environmental regulation in europe. Developers prefer germany or the UK.

In the popular cities which is where everyone wants to live, it's quite low.

They've been full for quite a while, turns out land in desirable places is not infinite and there's no supply. So don't increase demand by allowing wealthy foreigners to buy out everything.
