Every year, Forbes publishes the most expensive zip codes in the country. Atherton has been on top for the last couple of years and is now bumped to third place. Cities in Florida and New York took the top 2 honors. Hillsborough, California is #16, previously it was #10, but the data is a bit suspicious as the median price is overstated by a lot. I checked out a few other cities like Burlingame, California #182, and it’s way understated. Moral of this story – if you really want to know property values in a zip code, check with a local expert who stays on top of data.
