How do I divide profit fairly with investor?

[Micah Cook]

Hello BP,

I located a great investment opportunity on a foreclosure and I will be only be able to provide about 15% of the cash needed for the full-cash purchase. I pitched in to an investor and got him on board and he will be providing the remaining 85% of the cash for the purchase. 

I was wondering what would be the most fair way to divide the profits between us. He suggested a "percent in, percent out" idea where the percent of the investment you provide, is the percent that you get of the profit. I think that this is fair IF each person does the same amount of work and shares the same amount of responsibility. However, I located the deal and will be doing most of the overseeing and organizing while he will just be providing the majority of the funds.

I was wondering how you would go about dividing it, and also how much credit you give to finding the deal and being the one to oversee and manage the flip. 

Thanks for the help!
