Elon Musk sold a San Francisco mansion, which was his last remaining home, for $30 million

• Elon Musk sold his final home, a California mansion, for $30 million, according to MLSListings.com.
• Musk said previously he would sell his property portfolio to fund a Mars colony.

Tesla and SpaceX CEO Elon Musk has finally sold his last remaining home, after repeatedly saying he wanted to sell most of his possessions, including all his houses, to fund a colony on Mars.

The 47-acre property in Hillsborough in the San Francisco Bay Area sold on December 2 for $30 million, according to MLSListings.com. Mansion Global first reported on the sale.

The buyer was represented by John Bretthauer Real Estate Experts, per Realtor.com. The company didn't immediately respond to Insider's request for comment on the identity of the buyer.

Musk bought the house in 2017 for just over $23 million from Christian de Guigne IV, whose family had owned the property for 150 years, before listing it himself for $37.5 million in June 2021.

After failing to find a buyer for the property, Musk then listed it with Compass' Mary and Brent Gullixson for $31.99 million in October.

Musk had previously been criticized for keeping the Hillsborough property, despite vowing to sell all his houses. He said on Twitter in June that he had kept the 16,000-square-foot mansion to rent out "for events."

Musk called the property a "special place" and said he wanted to sell it to a large family.

Musk has sold his property portfolio to fund a Mars colony

Musk has said he wants to send 1 million people to Mars by 2050.

He announced last May that he planned to sell "almost all" of his belongings to fund the venture and that he "will own no house." Since then, the entrepreneur has sold his real-estate portfolio, which was once worth upward of $100 million. This includes selling three neighboring homes in the Bel-Air neighborhood of Los Angeles and an estate formerly belonging to the actor Gene Wilder.

"It's going to take a lot of resources to build a city on Mars," Musk told Mathias Döpfner, the CEO of Insider's parent company, Axel Springer, in an interview last December. "I want to be able to contribute as much as possible to the city on Mars. That means just a lot of capital."

Musk told Döpfner that he would have "basically almost no possessions with a monetary value," apart from stock in his companies.

"People will attack me and say, 'oh, he's got all these possessions. He's got all these houses.' OK, now I don't have them any more," he added.

Musk relocated to Texas from California during the pandemic. He said on Twitter in June that he lived in a property worth around $50,000 in Boca Chica, Texas, which he rented from his aerospace company SpaceX.

Musk reportedly lives in a tiny prefab home developed by Boxabl.
