15. Larchmont, New York (Average Household Income: $324,835)

Larchmont is located on the west end of Long Island Sound, and it has a lot of history. The oldest home in the town was built way back in 1797 by the nephew of America’s first chief justice of the Supreme Court, John Jay.

That home sits on more than twelve acres of land, and it is now known as the Manor House. It’s one of many estates in Larchmont and is also one of the few waterfront parks open to the public in the area.
