Creative agreement with Buyer

[Brian Cam]

Hey BP friends,

I recently ran into a new situation, and I need some ideas on how to structure an agreement.  The situation is as follows.

I have a coworker that knows I wholesale properties in my spare time.  He came to me the other day and said he wants to buy 2 single family homes near Binghamton (a college town in upstate NY) and he wants to work with me.  He has the properties picked out and the cash for downpayments.  I don't have a ton of liquid cash right now, so what would be the best way to structure a partnership?

Any and all advice would be appreciated!
