In 1998, Bezos purchased a 5.5-acre waterfront estate in Medina, Washington, a suburb of Seattle, for $10 million. His net worth at the time — one year after Amazon went public — was $1.6 billion, landing him on Forbes' annual list of the richest people in the world for the first time. The mansion was worth just 0.625% of his total fortune.
Since then, Bezos and his wife have acquired several properties surrounding their estate, creating a compound spanning more than 10 acres. Current estimates value the home at $70 million.
