I help my uncle out, who owns some property in that general area. You are going to have a very difficult time finding a 1 bedroom in decent shape for 3 or 400 a month.
I get $375 a month for a 700sq ft Bungalow in West Mifflin.
I’ll put a lookout and see if he is aware of anything, but this may be the Unicorn of domiciles you’re looking for here.
