i need to add that the right wing spreads misinfo about inmigrants occupying the houses of people (big lie) to fearmonger those who want to rent, pay for occupation insurance and offer seasonal rents (vacational rents renamed in a different way) only.

recent laws for housing regulation (declaration of stressed zones to limit the maximum pricing as example) are not being applied in a lot of municipalities (governed by right wing) and «owners» skip them by dividing a flat in rooms, they rent you a room which is not legally a flat/house so the law does not apply to them.

They only have the funds to do that because of wealth inequality. This is downstream of the massive growth in inequality.

Needs a wealth tax. Make holding more than 10m euros worth of property a yearly expense and the foreign speculators will invest elsewhere, and prices will come down.

Also the spanish budget will get a break.

Buildout and taxation would surely fix this. Everyone is doing everything else rather than building housing....sigh
