WatchForbes 500 Most Expensive Zip Code feature has bad data in every detail item. All have Days on Market (DOM) set to 200 and Inventory set to actual DOM from their own big table.
This article actually was to highlight Northern California zip codes that made the list (Burbed is a NoCal real estate blog), but Burbed readers Divasm and nomadic noted the screaming mistake in their detailed items. Don't know if this made it to the print edition detail. Since the online version has a Top 50 slideshow it's possible it did.
