I was able to pay the sellers mortgage company directly that had a 4% interest rate.

Thoughts about buying with a turnkey company vs. with an agent if buying move-in ready?

Is this the company that you mentioned? 

Big companies expanding in the area means employment and a strong tenant pool and high occupancy rates.

Watch out for fine print that requires an additional fee at closing - this is a huge red flag and how most flat fee companies make money.

Unfortunately, you may have a hard time enforcing anything about "guests" unless policy/procedures are outlined in your lease.  

My business partner and I have been speaking with a VC company that is heavily invested in NL and learned that if you purchase a building in a QOZ and hold onto it for 10 years you can avoid the capital gains. 

Find the right insurance from the beginning and you won't have to worry about them canceling a policy.

My last response was two years ago and my policy has changed since then.

You don't need amenities like short-term and the people looking for MTR has expanded from travel nurses to displaced homeowners, future buyers, just sold sellers, relatives coming into town, insurance companies, etc.
