My vote is to tax/regulate corporate and out-of-state owners. I think landlording should still be an option for everyday middle or lower class people to start a business. But you get cut off after your 2nd or 3rd property, or if you don't reside in the state. Most importantly, though, Blackstone capital should not be able to buy $4bn-worth of single-family homes. If they want to build new urban housing that costs that much, fine. but not allow them to compete at scale with everyday people because they have a tremendous advantage. I think many places would also benefit from a hefty vacancy tax as well.
