Rob Lowe – $42 Million, Santa Barbara

Each of their 20-roomed mansion comes decorated in an old English style updated with modern luxuries. Additionally, their estate also has resort-like pools with fountains. Certainly, for the couple and for their children, they should consider estate planning to secure their future.
