If buying a house there, do due diligence on its age, quality of original construction and any subsequent renovations. Get a good home inspector. A lot of Coal Region towns have poorly-documented abandoned 19th century coal mine tunnels under them which as the timbers collapse can cause subsidence so proper insurance is important.

If renting, make sure it's maintained to safe standards by a reputable local landlord. Plenty of instances of our-of-town or out-of-state slumlords out there.

Finally pay attention to the immediate neighbors and the condition of their properties. Often fires break out and due to poor construction practices and non-existent fire code back in the day, an entire row of houses can go up just like that.

None of this is meant to scare you out of doing this but not many people move INTO the Coal Region. Traditionally, people like my great-grandfather have always tried to get OUT, lol.

Good luck with your Dad.
