I don't see how UBI helps. It would help if home prices were low enough such that builders aren't incentivized to build, but high enough that people can't afford them. But that isn't the scenario. In the current scenario, UBI or any other form of rent subsidy is just going to go almost directly into property owners bank accounts.
UBI would simply increase housing costs. The only way it wouldn’t is if UBI was funded from a land value tax, but even that would require enough housing in non desirable areas.
