Here in my area of S Fl there are specific credit score requirements for some condo's and some apt complexes. I have seen a score requirement set by various owners too, but that is fairly rare for an individual owner to set a min score requirement. The most common score requirement I have seen is a minimum of 650 - under that they won't rent to you regardless. However, it is a small percentage of the communities that have an iron clad rule about the score.
