Loan terms with family and friends for buy and hold down payment?

[Andy Brown]

Team,

I'm interested in hearing how people have/might structure deals with family and friends for buy and hold. To add some detail, say I'm seeking 50k to go towards down payments on 2-4 unit midwest properties that bring in about 3-500 p/m cashflow. What terms/rates would you propose for a loan of 50k from a retired family member who wants steady income through retirement? What terms might you offer a friend in in their 30s for 50k who is just looking to diversify in a hot stock market? Assume both are actually looking for real returns and aren't lending simply as a favor. Also assume that there is proof of concept for the returns and this isn't a newbie scenario. Thanks for the help.
