I’d also recommend @Whitney Sewell's podcast The Real Estate Syndication Show, and other resources like the Joe Fairless podcast.

I'd look at that as well as the Zoning Ordinance and Subdivision Ordinance, which every Pa township, borough or city has, or if they don't have those docs, they are covered by the county codes.

Since you said you are selling your building I’d argue you already have been a real estate investor.

Not to mention, they weren’t aware of my entity information and other organizational details I’d previously sent (ie state formation, scope of work, etc.); easy stuff.

Reach out and I'd be happy to provide you with this analysis.   

If you're not having any luck with mortgage brokers (I'd search out the ones who specialize in investments), then go to your local REI meeting. 

If you have any questions feel free to send me a message and I'd be more than happy to help you get connected with some of these other essential people as well. 

I'd have to ask my wife who handles the accounting etc about the fee question. 30 to 45min a month for 62 properties Not bad.

I’d also recommend getting a few quotes, including at least one from a mortgage broker.  

Whichever direction you go, be sure to work with folks who understand this and gives you the confidence to take reasonable action - I'd personally take an okay investment and weather the storm for a few years that will eventually perform well, and do that each year - rather than take 3 years to wait for the best deal possible.
