Upper Allen Township (in 17055) is the 47th safest township in PA, but Mechanicsburg School District (17055) is a bit higher taxes than 17050 (Cumberland Valley School District). Anything with a Mechanicsburg address (whether Cumberland Valley or Mechanicsburg schools) is a good investment in a safe area with great schools. If you need anything else, please feel free to contact me directly. I grew up in Mechanicsburg, know it very well, and know what's going on in the market there. Hope this helps!
