If you head east from Seattle, across the Evergreen Point floating bridge, you’ll find yourself passing through some of the most affluent zip codes in the world. Surrounded on three sides by Lake Washington, and situated just to the northwest of downtown Bellevue, this little cluster of communities, which also includes Hunts Point and Yarrow Point, is home to some of Earth’s richest people, and has the real estate prices to prove it. The median home value is about $2.7M.
