Silent partner to pay for Marketing?

[Traci Howell]

I recently had a local individual that I have encountered several times in real estate deals to tell me he likes the idea of wholesaling. He has offered to pay a 2500/mo marketing budget for my business, but I have no idea how to set up a return on his investment. Should I pay him a % of profits? What if I put in my own marketing dollars- would that mess that up? What are your thoughts on how to structure a return for this person as a silent partner? thanks
