The broader problem is lack of housing that can be afforded by the non-wealthy, which is caused in significant part by zoning laws. If more housing was available, the increased supply would better match the demand.
It's also caused by the idea that housing should be an asset to make someone else money, rather than solely a place in which a person/family can live. This leads to the AirBnB culture, the landlord culture, and compounds inequality whilst driving unaffordability. I'm sure the idea is abhorrent to the USA, but perhaps removing incentives to be a landlord at every step should be considered... mortgages should be puniti…
The problem is what will happen is that any US regulations around this will end up targetting middle-class “landlords” who rent out an extra home. And the real issue of huge corporate real estate holdings will be just fine.
It’ll scratch the itch of people wanting to beat down someone in their neighborhood, "boomers", etc who rents out something due to petty envy, but unlikely to solve the issue meaningfully.
A lot of average people buy real estate because it’s one of the few inflation hedges left for them.
