How to pay investors back

[Brett Eskew]

Hello,

       A little back story on me, im 21, in college, and i want to invest in some multi family properties to help pay for college and the be used as semi passive income after college. Ive been talking with my dad about this idea and in a short story trying to convenience him to be an investor in me/my business. I would use his money as a down payment for the multi family and then pay him back with interest.

My questions is how do you guys go about setting up the terms for paying an investor back. I dont even know whats typical interest rate would be in this situation, for how long, does he own part of the property, or just get a certain amount back, and so on. I havnt been able to find any examples on BP as to what other people do. If you guys could lend some support/tips i would greatly appreciate it. 

Also for someone in my situation, do you guys have any tips on going and convincing a bank to loan a college student a few hundred grand(with a 10-20% down). 

Thank you for your help.
