Investor Non-Circumvention Agreement before P&S Agreement

[David Dunne]

Hi all. 

Would it be considered acceptable or ridiculous to ask an accredited and very active RE investor who is interested in a deal you are looking at (whom you hope to develop a positive relationship with and or/ partner or invest with you) to sign a non-circumvention agreement, prior to them seeing the deal AND prior to having the deal in question under contract? 

I do realize this may be a chicken before the egg scenario. Just trying to gauge it. 

Thanks.
