Recommendations for reading/resources on setting up partnerships

[Scott Brown]

My brother-in-law and I have 2 properties that we are renting and in the market for more.  We have several people interested in real estate investment but not in renting/landlording.  Can anyone give some advice on good resources to read or steps to take to set up a partnership deal between an investor and our company?  We are thinking of using the investor's money to buy a property, do a value add, refinance and then pay the investor back a predetermined return.  Thank you for any bits of advice!
