While only living here since 2010 and just starting to understand REI and all of the intricacies of the Pittsburgh market - take my comment with a grain of salt. I agree with @David Lee Hall, III that there is too much at play to give more than just speculation. I may say that because I look more at developments than data - data is historical, future developments create opportunity. Just my two cents.
That said, I agree with North Shore expansion to the surrounding areas, as that development continues & further comes underway. I also agree with @Samuel Vogt with Beechview and some of the surrounding areas of Dormont - Dormont has been up and coming and as younger generations look to settle down and migrate to suburbs, I'm partial to certain South Hills areas that haven't quite hit their stride yet.
But instead of just agreeing with everyone's previous comments, here is my curveball, a bit in line with what David stated about Moundsville. This is more of a long-term play and not necessarily a 4-7 year boom....but anywhere up and down the Ohio River (from Belmont County, OH to Pittsburgh), they are anticipating 5 cracker plants going up. In addition to Shell's current project - PTT and Exxon are already eyeing properties. I'm not as concerned about the cracker plants themselves (although that will bring jobs and housing demand) - but I'm looking at the bigger picture of petrochemical and plastics manufacturing, particularly up the 376 corridor towards New Castle/Sharon. A bit outside of Pittsburgh, I know...but it's worth noting the potential long-term development here.
And David, to your point about Moundsville's "why not" being the state of the energy industry - that is more of a supply/demand issue with both OPEC increasing output (although they're pulling back) and a significant lowering of demand due to COVID. Those are both oil issues, which actually helps nat gas commodity pricing (long story on why that's the case, but I'll save you all the boredom of my industry's dynamics) which is prevalent in this area. There are significant "why nots" though - specifically relating to the "climate change", "zero emissions", "no plastics", etc initiatives that are out there which would be more detrimental to these projects.
@Account Closed Might not be what you're looking for, but I wanted to give my opinion on something I know. I think your associates' differing opinions on so many neighborhoods being a possible "next Lawrenceville" are all potentially correct - it just takes one major company to come in and start development on an HQ somewhere....and there you have it, next big thing (you let us down Amazon!). Until something like that happens, I have a hard time believing that any particular neighborhood will be able to hold a candle to what happened in Lawrenceville. But again, I'll give the warning that I am no REI expert! lol
Like @Steven Ko stated, I would also like to hear your thoughts as well.
