The median sale price in Atherton was $5.42 million in 2016, four times higher than that of San Francisco. That figure is highly conservative, according to local realtor Tom LeMieux.
The ranking by Forbes probably did not take off-market sales into account, which made up one-third of home sales in Atherton in 2015, LeMieux told The Almanac. Those exclusive deals are transacted through real-estate agents but are not publicly advertised.
