Achieving money-partner's required rate of return

[Joe Christoff]

As I've been telling more and more friends and colleagues about my REI journey, I've gotten more and more offers from these individuals to be money-partners in future deals. While I'm not quite ready to jump into partnership agreements, I'm interested enough to explore how a partnership deal might work in the future. What I'm hung up on is how to make a deal work so that it produces a satisfactory rate of return for the money partner.

Example setup:
Person A is time & energy partner - no capital contributed, will be finding the deal and managing the property. Person B is the money-partner - will put up 100% of cash for the deal (ie. no financing). Everything will be split 50/50 and both parties agree not to sell until property doubles in value. Both parties on deed as tenants in common.

Putting myself in the money-partner's shoes, even with the expectation of long-term property appreciation, I would want some immediate return on my cash invested. Assuming a required rate of return of 5% (comparable to high-yield savings or a CD), the deal would need to yield a total CoC return of 10% (since everything is split 50/50).

I'm stuck because while playing around with numbers, achieving this return seems improbable if not unrealistic. Yet it seems others have figured out a way to make these types of deals work. In this example, would Person A forgo a claim to any profits until they are above 5%? I'm hoping someone can help me fill in the gaps on what I may be missing.
