Private Lenders: What mortgage/net forms do you use?

[Marc C.]

Hello Experienced Private Lenders: 

I am in the process of putting together my first private money investment: Loaning $90,000 to a couple from my Mastermind group for a fix-and-flip for 6 mos. When I have borrowed privately before, I just used the appropriate Fannie Mae note and mortgage forms for my state. Can I use those for this purpose as well? Are there any fix-and-flip particular clauses I should add? 

Thanks in advance, 

Marc C
