How to structure a deal with multiple investors…?

[Blake Petty]

So i have recently bought my first 3 investment properties last year and everything is going almost perfect (praise the Lord). 3-4 people who are close to me have heard what im doing and all are willing to invest somewhere around $20k-$25k with my next deals to make some money with me. Heres the problem: im ignorant on how to structure something like this and what kind of return i should promise them to keep them happy enough to reinvest on more deals.
