Fortunately, we are renting out a property in an area that has reasonable laws and regulations for landlords.

The lease survives the sale of the property and regulates termination.

1st... talk to a local attorney in your area and see if there are any regulations that are unique to your state, county, and/or city (or even subdivision in some places). 2nd... if the numbers work and you are up for managing six different tenants for a single property then go for it.

For example, right now in the name of regulations designed to protect investors (like 506b), sponsors are not allowed to share their performance information publicly.

Also, how do I safely talk to someone who knows both about real estate AND about tax, license, regulations?

This process is set forth and regulated by existing CH law.

The reason given was that their regulations had changed and they were not longer loaning to LLC's. 

the Portland City Council approved a limitation on rental housing application fees during its August 3, 2020 meeting, which will be added to the City’s Code, Chapter 6, Buildings and Building Regulations, Section 223.1.

I'd start pushing back on that, by researching your local laws/regulations on liens.

I have also been doing research on Property Management and Landlord laws and regulations but if anyone has resources that help outline them that they could share, that'd be incredibly helpful!
