Indulge me.. high ficos, low cash

A friend threw this at me the other day when he heard I was reading these forums. Are there any suggestions out there for ways to get involved in an investment with no cash, but the ability to use (risk) your credit to make a deal happen? The guy has ficos all over 800 and the thought was that this should be worth something to someone looking to do a purchase. The trick of course would be how to keep him from having an equal claim on the property (as we're sure the person with the cash would want), or liability for the mortgage (as he would want), but still help make the deal happen. Is this pie in the sky? If so, any suggestions?
