If you are interested in WORK you should check with the Public Housing Authority in your area. Each County has it's own Housing Authority. Most public housing is being demolished around the country and the former "Secton 8" vouchers are now "Home Choice" vouchers.
These people have to be placed in homes. Some of them are qualified to buy. So if you are interested in a captive audience and your commission generally being the first month's rent, you should do some investigating with Public Housing.
