what does paying back investors actually look like?

[Justin Wren]

So lets say im wanting to purchase a property to develop into a rental. i have 3-4 friends interesting in putting up money. so how do i structure the payback? in my head i was thinking that i would break it down by % of what each friend put in; then that would be the % of the net profits they would receive every month. does this sound right? or is there a better way?
