Family funding 1st investment

Good morning BP,

So I am in a blessed position where both my mother and my wife's mother are looking to help us get a start in start in real estate investing. My goal is to find deals through the mls or through networking at my local REIA and w/ BP meetups. I actually am going to my first BP meetup tomorrow. The reason I have access to the MLS is because my brother is a realtor and I will be partnering w/ him. Now once I find the deal, what are some ways that I can structure the funding from my 2 family members. Would it be best to split profits evenly with them, offer them a percentage return on their investment, or any other ideas.

Thank you for your help.
