Kind of my concern as well, maybe banning them from buying used housing but no restrictions on them owning new housing so that the money is even more focused on acting as a prime originator for new housing allowing it to trickle down later.

Also give like a 10 year or something proptery tax reduction for new construction also increase homestead exemptions to help homeowners but with increased proptery taxes to also encourge them to sell off and not rent housing after the intial honeymoon period.

Also would encourge them to purchase demolish and rebuild older housing and ruined housing so they could invest in it healing some of the older rundown areas.
