My 96 year old uncle who served in the Army for 20 plus years needs assistance with his housing situation. He lives in a trailer home in Arizona. It is very run down, and overrun with cockroaches. He is unable to afford to fumigate and fix up his home. Is there assistance available to help with his needs?
Your Uncle might prefer to live at a VA home where he is around fellows who were also in the military.

Help him, or do it for him, by contacting either a County Veteran's Service agency, or the AZ State Veteran's Agency if there is one. Or contact a service organization such as the VFW or American Legion, and ask about benefits to which he might be entitled.
These services are all free; don't get tricked into hiring someone to qualify him with the VA.
The County might also know of a place he can live while his trailer is being fumigated.
You can also try contacting local senior centers to ask if they know of shelters.
The city in which he lives may get federal funds through grants to help with emergency repairs. That's something to check out. I don't recall which department in my city handles this; it might have been Code Enforcement, or the Building department.

He gave up over 20 years for his country; his country should do something for him.
