Simple. Only individuals can buy single family homes. No renting of single family homes. And remove zoning restrictions to allow for more multifamily units.
Oh hoo hoo, when you talk about removing zoning restrictions things get hairy fast. The city of Houston has no zoning restrictions and from what I can tell (I’m not from there) some people love it and some people hate it. Apartments bring with it noise and generally clutter an area. You need nee infrastructure to manage an apartment, the tall place blocks the sun. Now if you’re in a city then you still have to think about where those apartments may be built. If they’re cheap and in a nice neighborhood then they’ll be snagged up so quickly. If they’re in a bad neighborhood then no one is going to want them. So what zoning restrictions would you recommend removing?
