Anyone interested in helping me figure a deal for a friend?

[Tracey Pera]

I am so new, my 'umbilical cord' isn't dry! I have a very newbie idea and if my math is correct it is a win/ win/ win. 

I have a friend who is looking for a MH and has $14K for a DP and would like to 'borrow' the rest and I told them I might be able to find an Investor to help them. 

My idea is this since I am doing this as a 'favor to them' to start out, I just would like a 'Thank you letter' for my files from them. 

For the investor I have THIS Idea:

18%, 20K ( five to me in cash from investor, this already sounds 'off' to me), Pmts $360, 10 year term.

The cash is for the deal acquisition. You would be paid 'back' the 5K in the loan amount. 

Is this a Win/ Win/ Win? 

I am new ,but I am not willing to 'give my time away', Thank you so very much for any advice. 

Ethics and Integrity are somethings very valuable to me, so if this crosses those lines, I sincerely apologize. If it is a good deal, I praise God for the idea.
