If you are unable to perform, per your partnership agreement, the entity could "fire" you and perhaps pay you a finder's fee of some sort (or nothing since you'd likely be leaving your partner with a busted flip).If the deal goes as planned, you would split any profit from the sale after all costs were subtracted.On the other hand, your partner could fund the purchase as a private loan to you using professionally prepared loan documents obtained from a lending attorney.

Line up financing early, hard money, DSCR, or private investors, and have two exit strategies ready, sell or refinance and hold.

I've done the brrrr model, house-hacking, sold str/mtr, and raised capital. 

Most private lenders won't fund an owner occupied live in fix and flip. 

The partner says no, and then the holding costs build to a point where the profit would have been greater if you dropped the price an sold when you brought it up verse holding out for that number you wanted.

Any tips for structuring a small gap partnership, private money arrangement, or equity split?

Sorry to hear that but what I can tell you is think of lending as buying soda - at the end of the day it typically flows to the top 2 or 3 major companies. the same is private lending, it goes to apollo, blackstone and a few others.

What advice would you be looking for on the private money part?
