Most if not all counties have some form/amount of subsidized housing. Not enough, generally, but some - In my county the wait time to get into one of these apartments is over 5 years. Google the county you want housing in along with "area agency on aging". You should come up with an office you can call to get a list of the subsidized housing options in that county. Although it's titled aging, most of them also serve people with disabilities as well. I worked at one, and got lots of calls from people on SSI who were having to become homeless and/or move away. It was (and still is) really sad.
