Or are you actually talking to a bank about buying the note so you can see the notes and credit on the owner of the property?

If not, I'm guessing it would be treated as a traditional rental loan, either conventional or DSCR, using market rents rather than the rent in the lease agreement.

Bank financing.

And the rub is I do not even need to withdraw funds from my SEP IRA because I already have enough in my bank account to show them. 

@Penny WilkinsonIf there are no comps, then I would try to ask community banks what they would be able to lend on it.

If E has any priority over B, for instance, I would not invest in this structure, given that my bank account puts me at a Class B share (side note, their Class B is a little more GP friendly on the surface, than other groups, but devil is in the detail).  

When you go to a Bank or Credit Union, they can only offer you what products that bank or credit union offer. 

Bankers are generally not aware of hard money loan options, and even if they are, they don't generally refer them when they believe they can approve a loan to you from their bank.

Although I’m sure the bank made it clear that rents would have to go up quite a bit in order to meet the monthly mortgage obligation.

I would, If in this position, take the equity in the form of a HELOC and purchase a cash flowing asset that would not only pay for itself but pay for the cost of the money while putting cash into my bank account each month.
