I'd say no to this. Sounds like a bad idea because you have no control.
And if you have no control / no decision making, then you're not really learning anything in real estate (you're just exposing your $ to real estate -- and you can do that with REITs which you already have).
But I'm not sure what kind of deal this is, if I hear you correctly:
1. You own 10% of the deal.
2. You can't make final decisions and have no control.
3. Your returns are solely based on your dad's position.
So you risk your money but don't have any rights?
How is this any better than
investing in a syndication where you've got teams of professionals that manage these projects country-wide and have established systems? At least in a syndication you can interview sponsors and grill them on their numbers and learn how to underwrite a deal professionally.
TBH this sounds like a terrible deal for you (risk $, no control, and doesn't seem like a lot of learning opportunities) and it doesn't make any sense why you'd do this.
Forget your dad being your dad. Would you do this with someone that isn't your dad but with your dad's real estate portfolio / returns?
