Hard money + Private Money

[Ron Bruce]

I have two family members willing to contribute private money on a flip. How would the following situation work out legally? And how would you consider the profit sharing in the end?

The funding would go as follows. (Using a $100,000 property as an example, $20,000 rehab, and $200,000 ARV). The hard money loan would cover costs except the $20,000 down payment on property:
Me - Hard money loan + $5000
Family member #1 - $5000
Family member #2 - $10000

I guess my question - is private money protected at all by the property if hard money is involved? Secondly, does profit for each party reflect their initial investment?

Thanks!
