The answer, as always when it comes to housing issues in Portugal or anywhere else, is to treat this as a supply side problem. Portugal has an influx of foreign funds through Golden Visa and similar programs. It should take that money and build social housing that is, at least at first, only open to Portuguese citizens. Think Vienna. In areas where building is a problem, just use funds to buy properties and turn them into social housing. I don’t know what restrictions there are on foreign real estate purchases. Personally I have no issue with owner occupiers. But any “investors” (including AirBnBs) should be made illegal or simply taxed into oblivion.
