The most expensive ZIP code in the US is no longer in Silicon Valley
For the past two years, the most expensive ZIP code in the United States has been 94027, which belongs to Atherton, California.
The Silicon Valley community is home to tech executives like Microsoft cofounder Paul Allen, HP CEO Meg Whitman, and Google chairman Eric Schmidt.
According to US Census data, the median household income for the area's residents is just short of a quarter of a million dollars annually — $220,583.
But it's not the most expensive place in the country to buy a house anymore.
That honor goes to ZIP code 11962 — Sagaponack, New York.
According to data from January 2014 to June 2015 compiled by the real-estate-listings site Property Shark, the median sale price for homes in Sagaponack was $5,125,000.
By comparison, the median sale price in Atherton was $5,050,000.
Set in the Hamptons, about two hours from New York City, Sagaponack is less of a draw for West Coast-based billionaires.
But it has its share of rich and famous residents.
Compared to that, Sheryl Sandberg's old house in Atherton, which sold for $10 million last year, looks modest.
