you leave individuals who own up to, say, 3 houses alone and start massively taxing anything further. 4+ house voting bloc can suck a dick. corporations will be forced to rent at obscenely low rates to the point that they will be stupid not to sell. they have a minimum tenant percentage to make sure they’re not hoarding, and have mandatory government evaluation for any sale. fail to do any of this for 60 days and your properties now belong to the people.
