Situation in Europe is often reported in misleading ways. Everybody calls it "housing crisis" - but we do not have millions of homeless roaming the street. It is actually a "moving crisis" - people want to move to nicer places but can't afford it. I.e. here in Germany, we have close to 1M perfectly habitable empty flats/houses - but they are in rural areas or the countryside. Indeed there is high demand for urban areas and cities, at the same time rural villages struggle to find and retain their population because everybody (especially younger people) move to the city. You might have heard of those italian villages offering houses for 1€, just to attract families and keep those villages alive.
