How many are vacant? Those are the first ones that need to be reallocated.
(Meaning, I'm not pro equity firm, I'm saying an occupied house is a house that is occupied. These 2mil new houses are for new occupants, not shuffled ones.)
I think the key point is ownership. If the house is owned by an equity firm, even if it's occupied it still counts as a house which could instead be owned by, well, homeowners.
