I'm a builder on 30A, - Watercolor, Seagrove, etc. Haven't had a deal yet in the past year or so that wasn't cash, which is good, they can't get upside down on a mortgage. We are building in one neighborhood where a 4 bedroom house is selling for what the building lots sold for back in the day, at least for now. We live on a little bitty strip of land with Gulf on one side, State forest and wetlands on the other, and a height limitation. All that adds up to not enough property for the demand. If you are thinking about buying or building, don't think long.
