I appreciate your response @Steve Olafson but don't really feel that not offering a preferred return is like not having confidence in your deal. REI is not a risk free business and market changes can't always be predicted but that is what you are doing with a preferred return. I get how it can be a big plus for the investors but I don't see the upside for your time investment to predict a guaranteed 5 year trend in any market. I feel that a reasonable sponsor/investor split is fair without the guaranteed return percentage.
On the flip side at a certain point I can see larger investors and more seasoned lenders would have certain expectations and preferred returns may be a requirement. These guys are usually playing in much bigger business deals and already make a certain average percentage over time.
I think it is a case where there is no right or wrong answer across the board and each deal has to be viewed by its merits, returns, and how much is being lent compared to your own investment both time and money in the project. But I can see your argument and Michael's, depending on the situation, being the right choice.
Thanks for getting me to think deeper on this subject,
Dave
