5 Did the COVID situation play a role in delaying the Close? 

I'd challenge you to try to make this exercise more quantitative than that qualitative.

If so, the LLC would have an agent/manager who could hold the role of "owner" (even if it is you are your partner), thereby giving you a semi-layer/cloak who can be the theoretical bad guy if needed. 

It actually was a great exercise for me as well 

If the bonus depreciation rules are extended then you will have the option to repeat this exercise down the road rather than do a 1031 exchange. 

We are looking for others who would be interested in playing any of the common roles needed in the GP, such as, KP, loan signatory, or 1000+ units already in their portfolio, etc.

@David M.The lender can exercise the "due on sale" clause if the name(s) of the buyer are not the same name(s) as the members identified as the owners of the LLC.

I see tons of vets in that role. 

This is the role of other financiers, but don't expect to find primary mortgage market rates for speculation. 

None of those were engineering roles, but I learned a lot of things that make me a better investor (and agent) today.As you can see from my story you don't have to work as an engineer, but it opens so many doors and job opportunities.
