I have a deal. Not enough capital. Don't want to get ripped off.

[Jarrett Babcock]

I recently came across a deal on a duplex that has awesome numbers. Come to find out, the owners are actually selling a package of duplexes: 3 others for a total of 8 doors. I thought it was a single duplex at first and I could handle it, but the four duplexes is too good of a deal and I do not have the capital to lay down.

I want to get an investor in my area (Atlanta) to go in on the deal with me. How can I do this without getting screwed over? I have multiple avenues to find an investor, but I don't want to give the deal away without getting at least something in return other than "valuable internship experience." 

How should I approach this?

Thanks for any help

Edit: This is my first deal ever
