Oprah Winfrey — $50 millions, Californie

One of the most well-known women in entertainment, Oprah is worth an estimated $3 billion (yes, you read that right). She has several real estate investments, and her biggest purchase is a house that is 2,300 square meters and is worth more than $50 million. The house also has 16 hectares of plantations. According to Forbes magazine, the place is now estimated at 165 million thanks to all the renovations it has undergone. The house and its surroundings were built as a fortress. We have no doubt she’s probably the most confident in the neighborhood.
