Buying with investors, splitting profits

[Cris Mullen]

Looking for some input on how to break down the profits. Let me propose a few scenarios: First three buy and hold rentals.

1. Person A finds the property and negotiates the deal, manages the property. Puts in 50% of down payment.

Person B does nothing except contribute 50% of down payment.

2. Person A finds the property and negotiates the deal, manages the property. Puts in no money.

Person B does nothing except contribute 100% of down payment.

3. Person A finds the property and negotiates the deal, manages the property. Puts in no money.

Persons A, B and C do nothing except contribute 100% of down payment.

How would you split up the monthly profits and how would the stake in the equity of the house be divided?

4. How about this flip. Aspiring investor partners with realtor on a flip. Investor puts up all the money. Realtor, who is an experienced flipper, walks aspiring  investor through the process using her network of contractors.

Thanks!
