Oprah Winfrey –  $50 Million, California

It’s only right that one of the priciest properties on our list belongs to one of the richest people alive. With $3 billion in net worth, Oprah is the owner of a multi-million-dollar real estate portfolio, and her biggest investment is a 23,000-square-foot safe heaven. Located in California, the lavish mansion, built like a fortress, spreads across 40 acres of green plantation. Even though its worth is estimated at $50 million, according to Forbes, this palace is worth at least $165 million now due to Oprah’s expensive taste. We can’t imagine the home insurance cost.
