They are all in person as far as I know.

Its the persona not the title that makes someone good that can do all the things you talk about.Ok, that is enough ranting and raving.

If I'm not mistaken, double closing is essentially I enter a contract that includes person A - person B (me) that only involves the rights to the property not the property itself, then once that's complete, I would sell that contract from person B - person C.

AZREIA still has meetings, (azreia.org), they had one in person a few months ago, back have returned to all online for now. 

Make sure you get at least that in the form of rent for the lease-back.Lastly, I'm sure your agent is great at what s/he does and that is why you chose this person. As

Are you willing to put up with that kind of person as your Landlord for the full term?

For example, a problem from property A can't take assets from property B.However, also keep in mind that 1031 exchanges must be from the same person to person. A

For example, if all other conditions were the same and person A was willing to put down 5% of house and person B was willing to put down 20% of house would that have an impact on who the seller picks? 

So, person A may pay the bills, but person B reviews all the financial statements and could theoretically catch person A if they start stealing from the company.So, my comment earlier, you shouldn't need everyone to have check-writing capability. 

I would appreciate your thoughts on a few hypothetical ideas.If its one person, a 3x ratio suffices.
