What would make the friend move? If they moved, where would the income come from?
In Buffalo, an extremely nice apt. or a flat ( half a house, often 3 bedrooms) can be gotten for under $1200. However, most will not be handicap accessible and it sounds like he may be looking for that. At 18, and staying home to be his mother's nurse, he won't have an income. Where will the siblings be? Will they take out the lease in their names to guarantee payment? What income will they have if they move here?
These are all very reasonable questions that a landlord will ask -- starting with 1) who's paying and 2) what is the job [stability/salary]
I suggest your friend look into not-for-profit agencies for services for his mother -- in the Buffalo area, there are religious ones which have lots of resources. Also, he needs to check into govt. programs (
HOME Contacts: New York - HUD ) -- that goes to the US govt H.O.M.E. program. They may have resources for him. Try the County Social Services.
2 room apartments are not right for 3 siblings and a sick mother.
