Best areas in Pittsburgh to invest

[Jalen Byrd]

What are the best areas to invest in in Pittsburgh and the surrounding areas? I am looking to purchase my first property shortly and plan to purchase a duplex and house-hack the other unit. I am newer to Allegheny County and do not know the county too well. I have noticed that duplexes closer to the city need more rehab and are more expensive.  What are some of the best areas to invest in?
