my HVAC is relatively new but makes buzzing noises and I want it to be checked.

I would also keep an eye& ear out for the emerging innovators, every significant economic shift and calamity breeds innovators and those innovators require seed capital, think Facebook, Google, Netflix and so on, those early $ investors made multipliers on their capital that makes any other investment pale in comparison.

So an owner selling ends up with a bunch of white-noise. 

Consequently there might be a ton of "email noise" that a busy broker doesn't have time to wade through.

I also invest out of state and have a solid core 4 to aid me and be my eyes and ears on the ground... and I have not had any issues in a city that has its high crime areas give the entire city a bad name.

Outside of BP books, I have read Rich Dad (of course), and some mindset books like Think & Grow Rich, but if there are specific business/real estate books you recommend, I am all ears. 

Those answers are "noise" and will steer you towards an emotional decision and a bad investment. 

Only time will tell which sensors can be aggregated into useful data versus what inherent noise there will be.

We are also open to all other possibilities (wholesalers, REO’s, foreclosures, etc.)The purpose of this post is to introduce myself, but I certainly would not turn a deaf ear to sage advice.

Neighbors don't think twice about reporting offending airbnbs to the city for things like noise complaints or parking infractions.
