Also a transplant. One unique thing about Pittsburgh is that neighborhoods can vary a lot block-to-block. I recommend visiting the actual block you plan to live on a few times on different days and times to get a feel for what it's like before you commit to a place.

Also, the rain here is no joke sometimes. If you decide to buy a house, pay attention to potential drainage issues. It is shitty to deal with your basement repeatedly flooding.

Lastly, I am not sure where you're coming from, but compared to other urban areas, I have found our public transportation less accessible. Fewer busses, especially during evenings and weekends. If you are planning to commute to work by bus, look up the nearest stop and how often the busses run.
