Cash flow is definitely the biggest challenge; both in terms of finding properties to buy that cash flow with a loan on them and just company wide given interest rates and labor/material is up and, at least where I'm at in Jackson County, MO, taxes are way up too. 

I'm looking to connect with local investors, agents, lenders, property managers and contractors who have experience in these areas. :-) 

I also recommend you start looking for a professional property manager, at least until you educate yourself enough to run this solo.

I'm with a third-party Property Management all over Houston managing a little over 300 Single-family or Small Multi-unit rentals!!

Quote from @Noah Laker: I'm a local broker and investor, and manage 100+ Airbnb properties for clients.

You can complain to the Realtors managing broker.

I see Jeff S. responded he is one of the most experienced lenders  PM  lenders who owns his own company here on BP..

You are definitely going to want to get a lawyer and as soon as possible.This will sound harsh.In your story, you have made a number of very poor decisions about how you purchased and managed this property. 

I would like to continue using my excavation company and network of contractors as a vessel to push deeper into this realestate thing.

Depending on the type of commercial you want to get into my suggestion is to go work for a company that does commercial real estate as learning from people who do it and getting paid at the same time is not a bad strategy
