Providing Hard Money for a friend

[Eric Kissinger]

Hello all, I recently was approached by a friend who is interested in purchasing his 3rd fourplex. He needs some hard money to get into the property. What is a typical strategy when providing hard money for a down payment on someone else's loan? Should I be looking for a solid cash on cash return? How many years should I allow for repayment? Not really sure where to start, any advice is much appreciated.

Thanks!
