It's my understanding that there are infinite ways that these deals can be structured, but I'm just looking for one example, broken down, so I have a jumping off point to become creative.

Besides, if I can borrow everything (25% from line of credit and 75% from portfolio lender) for the MF, that is essentially "no money down" and my return in infinite. 

I bet without the strong partnership 14 days might have been a tight timetable.I really respect your decision to partner. 50% of a deal is infinitely better than 100% of nothing, if you had never got started.

This concept deserves a much more in depth write up and can be looked up under names such as the 770 account, Income For life, Infinite Banking, etc (no I do not sell insurance, nor have I received or anticipate receiving any reimbursement for these statements).

This essentially gives you an infinite rate of return since you should be able to buy with no money into the deal now.

Since I had no money in the deal it was an infinite return.  

Decent pay, infinite stability, good hours and VA loan advantage. 

If I cash out and get my $45k back, I then have $0 invested in this house and the returns would be infinite (until a new roof, HVAC, etc is needed).

I started in the business back in 2002, and came from a tax accountant background (real estate is infinitely more exciting).

Though unlikely, your exposure to loss is infinite.
