I live in a near by mon valley borough and we don't have any problems but would be surprised to hear any part is among the safest in the state. Geographically Pittsburgh is larger and more economically diverse. If you have a job lined up I'd look at commute options. Public transportation in general sucks but there are a few good routes. Real estate is somewhat affordable but keep in mind most of the houses are older. Have the house checked out. If looking to buy a new house there are not many options in the valley. We have the Waterfront area with shopping and newer rentals near the river. If you're near there you can walk for most shopping.
