@Chris Mclaughlin  Nationally HUD determines the "Fair Market Rent", which is the Median rent and is broken down by either zip code or for the whole county.

None of this is to scare you away from doing it, because I think it is a needed service, a good thing, and can be a real cash printer, but just wanted to prep you for a potential unforeseen hurdle down the road.Lastly, always make sure that you are compliant with city/county codes and have any required licensing etc.
