The only way I see out of this mess is to ban ownership of SFH by anyone other than…single families as primary owners. Corporations, foreign owners, secondary homes, etc.

But we need to address other issues too: zoning (make Houston’s approach nationwide) and construction costs.

Maybe a home owners break, and a second weaker first rental/vacation home break would match the current approach (and dodge more of the individuals who'd kill the legislation for for your idea. Alternately, a discount for occupied properties.

I was initially thinking corporate owned rentals or anyone with more than 2 properties, but the above seems cleaner.
