In addition to her obvious success in Hollywood, the Australian actress, who has one daughter from her previous marriage to Matt Lattanzi, can count many real estate holdings and deals in her portfolio (via Celebrity Net Worth). She has owned property in California, Australia, and Florida — and reportedly profited handsomely on at least a few sales. For instance, the star sold a stunning horse ranch in Santa Ynez, California for $5.4 million in 2019 (via Today). Her property "down under" sold for just a hair more the same year (via Hello!). Since she bought that home in the 1980s, we're guessing she did okay on the sale.
All told, between her acting and singing — The Richest estimates she could have earned as much as $10 million from record sales alone in 1981, and millions of dollars in the years following — and her real estate deals, Newton-John is worth a jaw-dropping $40 million.
