In the housing sector, bans or restrictions on foreign investors is a useful measure that I believe should be extended beyond the two-year period.
Another possible measure would be to stop renovictions. I don't know who has jurisdiction here, but the idea would be to penalize owners who purchase a rental property and sell it after six months, one year or two years. In a renoviction, the new owners pressure renters to move out, then more or less renovate the property and ultimately sell it. If they don't sell it, which is rare, rents are doubled or even tripled.
