So, simply delaying closing a few weeks eliminates the issue entirely. 

@Kris HaskinsA lot to unravel but if they recorded your deed for purchasing the property prior to the ratification of the sale then that creates issues which the lender should have gone with your closing.The agents and title companies in this are a mess as how did it not show up on title or with the listing agent what was going on.

My tenants have been amazing no issues and they always pay on time or early.

What digging I've done has been in valuing professional services practices (same issue: owner does the "labor", has client loyalty, etc.) as well as medical practices (patients loyal to a doctor more than a physical address).  

Most are fine with that, but a few will have problems with it and claim there are legal issues, etc..

Just make sure you get enough of a down payment to cover issues if you need to take the property back.  

The only issue is the tenant. 

I have had many work group bookings with no issues.

It increases complexity and cost dramatically and thus should be avoided.Whether you need an LLC at all and other legal protection issues - now that indeed is for attorneys to answer.

You do not want to have an issue with fair housing or the many JC regulatory agencies.
