I haven't heard of any UBI experiments, only giving BI to some people, which would not have much impact on things like average rents over an entire region.
It's more than when minimum wage goes up (which has a similar effect on people at the lowest end of the wage earners - their income goes up by X) the effect is not that food/housing immediately captures all of that X, it captures about 20% of X.
(I appreciate that I'm not offering sources, and am going from memory here. Sorry, if I had the time I would try and track them down.)
There are multiple points against such comparison:
1. Minimum wage goes up - for some amount of people. Most are not feeling it as they are not on the minimum wage or not working.
2. Salary is not UBI, it is actually earned, taken from revenue.
