I read a story, maybe 20 years ago, about this very old french woman that had an amazing house overlooking the ocean. A middle-aged rich guy showed up and bought the house on that conditions you mention. The woman could stay in the house until she died. This woman went on to become the oldest person in France and the guy died many years before her.
