It is a sad fact of life that the best outcome for everybody is to let the economically productive take first pick of any available resources; because they will by definition take them and turn them into more resources.
This idea that someone has a right to live somewhere because they were there first is not unreasonable, but the path of least suffering is that people pay the market price for rent.
There needs to be pretty overwhelming evidence that the problem is with what consenting adults agree to rather than the government being unreasonable with the rules on constructing new building. I'd bet that the US hasn't reached that threshold yet.
