Commercial development deal structure

[Matt Bickle]

I am looking for help in structuring my first development project. My main area of expertise is Oil & Gas exploration/production, however, I have two partners that have convinced me to join in on a commercial development project. With Oil & Gas projects, investors shared an 80-82.5% stake in each project leaving between 20-17.5% for the landowner and oil company who organized and operated the prospect. I am curious if there is a "standard" percentage that a developer is "carried" for organizing and overseeing all operations regarding the project. The number that came to mind first was between 15-20%, is this too high, too low? Any experience in this aspect would greatly be appreciated. Thank you.
