I feel the numbers that show investment groups that own X number of homes is highly misleading. More than likely these investment groups form multiple companies when they buy up the homes. Likely state or regional. From there the larger parent company is invested. So I wonder if there are hundreds or thousands of "small" investment groups that are essentially a shell for a larger private equity group.
So my big worry is that the Trump admin will say they are going to only eliminate the most obvious cases and the problem will remain. The LLCs and shell corps, etc.
EDIT: Also it does not address the massive amount of housing stock that is foreign owned by people that don't even live in the country.
