Longer answer: As with any other commercial investment, it'd depend on the cap rate, cash on cash return, etc. And it would also depend on who the other partners were, and who'd be managing the investment. And I'd do the same due dilligence as I would on any other investment.
I guess it all depends on what the risk level is, how solid the partnership agreement or other legal binding contracts are. If you can make a ROI higher than you could w/ anything else that requires that small of an investment..... why not?
