Crowdfunding 50-Unit Deal: Are These Fair Terms?

[Mark S.]

I have an opportunity to invest in a crowdfunding, 50-unit opportunity with the following terms:

- 8% preferred return

- 25% net rental income

- 50% profit upon sale 

Property management fee is 7%.  Markup on maintenance can't exceed 10%.  

For a passive investor, would you say these are fair terms?
