How to Develop 4 Acres of land near Bethany Beach, DE

[Matthew Wolfe]

We have 2 rectangular lots that total around 8 acres (4 acres each, and directly across from each other).  Based on what I know of the area (and I know it fairly well), this would be perfect for a 3-story commercial building.  While I do not know the highest & best use in current market, (Idea #1; retail on 1st floor, office on 2nd floor, and residential on 3rd floor, Idea #2 All 3 floors residential), I'm trying to figure out how to go about developing with a builder in a way that allows us to maintain control of the property as a whole when finished.  Assume we own the land outright.  Would you recommend putting out an RFP to Local & Regional Builders for design proposals & cost to build, or something else??
