A more practical solution is housing coops like the BRF system in Sweden. Individual landlordism is mostly banned (there are some company rentals though) - you buy the place you live in, and there are restrictions on renting it out (no more than 2 years in a row, etc.). It's helped a lot here. I don't think that social housing is a good solution. It's a complete disaster here in Sweden, with 12+ year waiting times, a…
Has it really helped? I remember talking to a young Swede a while ago, just a few years out of college. He said he bought a flat in Stockholm pretty much as soon as he had a job, and that the price appreciation since has almost outstripped his salary.
We ended up paying the same price for relatively similar flats, but in BCN that's much harder to achieve, and they are older and need renovation - and there are thousands of AirBnB slumlords buying up everything.
So yeah, the price increases have been a problem (and hit me badly combined with the interest rate increases) but it's still better than most of Western Europe.
