How to divvy up with partners on buy/holds

[Steven C. Suarez]

Hi friends, how do y'all usually divvy up money made from buy and holds that a partner/partners have helped you to buy? For example if I bought a 100k home in my name and needed 20% down and a partner gave me 10k (10%) to help buy it. I obviously won't be able to pay him back right away if I just planned to buy and hold it. What kind of arrangements do y'all usually do or recommend? Same question with multiple partners. Thanks!
