I am a new Philadelphia RE investor. I am currently looking to begin my investing career by house hacking with a duplex by the end of this year. I am looking to see what are the best areas in and around Philadelphia to buy duplexes. Areas which are growing and are possibly opportunity zones.
Welcome to BP. You need to have more specific questions to have replies.
Philadelphia has a ton of good and bad neighborhoods. Unless you have any criteria it's impossible to give you any recommendation.
You can see all of the opportunities zones on this map http://dced.maps.arcgis.com/home/webmap/viewer.html?webmap=b0bd4d703ddc498fb0a993a00d77ed4c
