The daughter of Bill Gates and his ex-wife, Melinda French Gates, is living in a grand $51 million Tribeca triplex penthouse with its own plunge pool.

Microsoft founder Bill Gates is reportedly paying $43 million to purchase a 5,800-square-foot beachfront home in Del Mar.

Each fall as part of Microsoft's charitable giving campaign, people at the company donate products, services and experiences for their fellow employees to bid on. The item that typically fetches the highest bid is a tour of Gates' Lake Washington home for the winner and a small group of friends, guided by Gates himself. After the tour of the 48,000-square-foot complex, which is located outside Seattle, the winner gets to nosh on some appetizers, TechFlash reports.
