Check out this site called (mods can remove if I'm not allowed to post a name) BiggerPockets. It's a real estate website for investors/flippers/rental income. There is a section that is for rental/landlord questions. There is a wealth of knowledge there regarding varying sites to use for background and credit checks. I'm assuming they have a search function on their site. You don't have to sign up or anything to look at the information.
