Real Estate Investing Agreement

[William Smith]

Hello 

I have investors that will fund my rehab . My plan to pay them interest only payouts until I refi to return their initial investments.  What I would like to know is how to structure the deal on paper to ensure the have an equitable position during rehab. 

Does anyone have any documentation/ agreement I could model after?  Or whats the best way to handle the deal? I will have 3 separate  investors on the project.

Thanks!!!
