Overall Scranton's crime rate is relatively low for a city its size. Most crime that occurs is either domestic-related ( when one party assualts a relative or friend) or people involved with the 'dark side'-drug deals gone bad, etc....the types of crimes you will find anywhere. But for the average person who's not involved in drug deals, it's a safe city and that's true for the surrounding areas as well.
You should be able to find a nice selection of homes in that price range...but Carbondale?

It's not a 'bad town' but you can definitely find more attractive towns within a short commute of Scranton.
