Corporations bought 15% of homes sold in that quarter, they don’t own 15% of the homes. The total owned is much less. But regardless, that does not impact HOUSING, it impacts home buying. Separate issue.

If 100 people need somewhere to live, and there are 98 houses, 2 people will not have housing. Now imagine a corporation buys 10 houses and rents them out to 10 of the people. Still exactly 2 people without housing. I care more about helping the people who do not have places to live.
