Microsoft cofounder Bill Gates and wife Melinda Gates, an Ursuline grad, bought a home in Del Mar, California, for $43 million, according to House Beautiful. They bought the 5,800-square-foot home from Madeleine Pickens, the former wife of billionaire T. Boone Pickens. The home features a spa, theater, pool, tennis court, greenhouse and guest houses, according to the San Diego Reader. (They’re still keeping their home in Washington state.)
