MDHA is the public housing authority for Nashville. They work off of enormous waitlists that are opened every year or two for only a week or two at a time. These waitlists must be accessed online. Some of their units are only open to certain demographics. To see if any of them are currently open or scheduled to be soon, check this website and do so regularly http://www.nashville-mdha.org/apply_afford_housing/ . They will not accept any application if you go in person even if they are open online.
