Elon Musk, the billionaire CEO of Tesla and SpaceX, has reportedly sold his last residential property, a historic 16,000-square-foot mansion in Hillsborough, California. This sale marks the final step in Musk’s well-publicised move to divest his real estate holdings as part of his broader goal to simplify his life and focus on his vision for a “multiplanetary” future.

Musk’s Guignécourt mansion: A historic estate in Silicon Valley

The mansion, known as Guignécourt, is a significant property both in size and historical value.

Built in 1912 by French nobleman Count Christian de Guigné, the estate sits on 47 acres of prime Silicon Valley real estate, offering breathtaking views of the San Francisco Bay and the city skyline. The mansion features seven bedrooms, nine and a half bathrooms, and several grand living spaces. Among these are a living room, a library with leather walls and a fireplace, a gourmet kitchen, and dining and music rooms designed for large-scale entertaining.
Despite its historical roots, the mansion has been updated with modern amenities. The property includes a fibre optic cable system, a high-end security system, and an interior sound system. Several original features of the estate have also been meticulously restored, preserving its early 20th-century charm while integrating contemporary conveniences.

The sale: From listing to contract

The mansion was first listed for sale in June 2021, following Musk’s announcement on Twitter that he intended to sell his last remaining home. Musk expressed a desire for the estate to go to “a large family who will live there,” signalling his hope that the historic property would continue to serve as a family home.
Initially, the property was listed at $37.5 million. However, after several months on the market, the price was reduced by $5.5 million in October 2021, bringing it down to $31.99 million. Over the weekend, the property went under contract, as noted by the Multiple Listing Service. While the final sale price and the identity of the buyer have not yet been disclosed, the transaction is pending completion.

Estate’s legacy and features

Guignécourt is not just a home; it is a piece of Silicon Valley’s history. The estate’s extensive grounds include a reservoir, a pool and pavilion, hiking trails, a three-car garage, and an eight-car carport, all meticulously maintained and landscaped. The property had previously been listed for $100 million before Musk’s purchase in 2017 for $23.4 million through Gatsby LLC, a company associated with his family office, Excession.

Musk’s real estate divestment

Musk’s decision to sell his last remaining mansion is part of a broader strategy he has pursued over the past few years. He has been gradually selling off his real estate holdings, a move he has described as necessary to focus on his ambitious goal of making life multiplanetary. Musk’s decision to simplify his life by shedding these assets has garnered significant attention, reflecting his unconventional approach to wealth and property.
