Terms for outside cash investor for rehab opportunites

[Chad Bauer]

What type of terms do you offer for someone looking to invest cash with you to purchase a property? I have been approached by a couple of people I know that are interested in giving me money and want to make sure my offer to them is fair. My plan is to return their money within 3 months but I'm sure I'll need a contingency plan in case that doesn't happen. Thanks for the help!
