7. Hearst Castle – $191 Million
This majestic residence in San Simeon, California may be recognizable to many as one that was featured in the movie The Godfather. It has also hosted its fair share of dignitaries including Former President John F. Kennedy and his wife Jackie, Bob Hope, Clark Gable, Greta Garbo, Winston Churchill, and Franklin Roosevelt. Although the former owner of the 27-room estate, newspaper magnate William Randolph Hearts has passed away, the property remains in the hands of his trustees. It is now regarded as a heritage and tourist site through an agreement between the California Park System and the Hearst Estate.
