She recently toured a $68-million 30,300-square-foot, English-manor-style five-story 19-bedroom 12-bathroom mansion in Alpine, New Jersey.
Alpine last year was named by Forbes magazine as the most expensive ZIP code in the country. Its celebrity residents include Eddie Murphy, the Jonas Brothers and [Yankee pitcher] CC Sabathia.
The estate eyed by Oprah is the most expensive in Alpine, with walnut and marble floors and Venetian plaster walls.
The mansion is located about 20 miles north of Manhattan.
