Excuse me being naive but why? It would be a unique situation and as such any predictions of what's gonna happen are purely hypothetical.
Your last point is kind of moot as it could be used to argue against any kind of wage or income increase for poor and middle class "They just all gonna spend it paying their landlords".
If the basic income accounts for "average living costs" then ideally the average rent should be calculated too and factored into it, so landlords can't just jack up rents and expect their tenants to "reach through" their UBI.
A UBI would give the poor and middle class at least some bargaining power with employers, that's already progress. The whole situation about affordable living space becoming rarer and protection of tenants are valid concerns, but you can't expect a UBI to fix everything, different issues need different approaches and solutions.
But that's not an issue with UBI but rather with landlords having such free reigns over the rents they are charging.
Rent control and protection of tenant rights are ongoing issues, especially in countries where renting is the prevalent mode of living, as such many countries governments are trying plenty of approaches.
The issue with the US being that it's a rather touchy subject to discuss, but its nonetheless relevant because more U.S. households are renting than at any point in the previous 50 years [0]
So a discussion about that particular topic is most certainly needed, but you can't expect UBI to fix every single problem on its own, no solution is ever as simple as that.
