We're living in times when franchises go out of business overnight, but healthcare will never be since it is essential. 

I have experience with this business model. 

The business venture that went sideways?

Having trusted resources in market have been helpful in managing our properties and contractors especially when my non-real estate related consulting business is in its busy season.

A land contract has been signed in the county between me and my buyer documenting this transaction. 

I've actually pulled the plug on investing to focus on our general contracting business because investing was more of a distraction.  

I personally used business credit cards to BRRRR a deal—no money came out of my pocket.

Sights are set on all types of REI, but this will be a great start for us.I have been in the mortgage business for over 20 years.

The liability coverage is way better, the building coverage is often better, and commercial policies typically cover loss of business income as well, which a homeowners policy isn't going to help you with.California + wildfire area + STR is super tough. 

This is really going to depend on the state you are looking to do business in.
