This seems like an oversimplification. If the landlord issue like you describe is really a core problem, then they can pass a law like they did in California, capping rent increases at 5-10%/year. That problem doesn't seem tied to UBI at all. Rice would also likely increase in price due to higher taxes needed to pay for the UBI.
