Housing Bubble 2: Return of the Ugly

Tax empty properties owned by corporations.

Ban foreign investors from buying up properties.

Increase taxes on non-primary, non-secondary properties dramatically (so if you own a home and a vacation house, you're fine, but you'll pay way more in taxes if you own more than that).

Release federal funds earmarked for subsidizing the mass construction of low and middle income properties that must be sold at below market rate in order to qualify for the subsidy.

Re-evaluate zoning laws nationwide to make it easier for residential housing to be built into areas that it currently makes sense but is forbidden due to draconian zoning laws propped up by NIMBYs.

Sorry if any of the above hurt your bottom line in the end, but it's more important to ensure that everyone has a place to live than it is to protect the "ownership as a means of passively generating wealth" model we are currently living under. The line cannot go up forever.
