Traditional Mortgage down payment loan legality

[Jacob Yates]

The title seems pretty self explanatory but I will clarify. I am looking to find financing for a rental property. I don't have the down payment for it, but I have a friend who is willing to loan me the down payment for it. I read on another post that Fannie Mae forbids using loaned money on the down payment. So the question is if I have a personal loan made to me can I take that and use it for the down payment on an investment property?
