NDA for Investor and General Contractor

[Ben Sealey]

Hello,

I have been approach by a builder/general contractor who is building 600k houses.  He is currently building four houses and needs money to move to his next build.  He has approached me.  I am interested.  Do any of you have an NDA you use that protects both parties? I think the main thing they want to protect is the info they have gathered for a couple of floor plans they have.  Budgets, floor plan, etc.  

I would also like to chat with other investors on here that do this.  What is the basic formula for payout.  

Thanks,

Ben
