Hilary Duff – $6.2 Million, L.A.
When she was 29, actress Hilary Duff already owned this cool mansion with its Mediterranean design. She was by this time far from being the innocent-looking teen who many loved to watch. Her characters had become tough, feisty, and strong-willed. This 9,277-square-foot house shows off a number of luxury touches like a cognac room, wine cellar, and everything in-between. Being a child star gave her a lovely nest egg to crack open as an adult. In 2019, Duff is 31 and has been romantically involved with NHL player Matthew Koma since 2017. The two had a daughter in 2018 via water birth at home.
