Partnership has no cash to put in deal but brings other value

[Bret M Rankin]

I would appreciate some advice from those of you with partnership deals.  I'll set the seen.  Student rental at the local university.

Purchase price $105,000

down payment and closing costs $32500

current rent is $2000/student/semester x 5 = $20k

property cash flows $250/month

I have a friend that would like to partner on the deal and he brings a great deal of value. He's a coach at the university and can put 5 scholarship athletes in the rental for $2700/student/semester x5 = $27000

now we cash flow arounnd $800/ month

Problem is he doesn't have cash for %50 of the down payment.  He lives close and could manage as well as  put his players in each school year.

What would be a fair percentage to give him for this value?
