Back in 2020, one of the world’s richest people vowed to sell “almost all physical possessions.” Sure enough, Elon Musk —who added he “will own no house” — has been offloading his real estate portfolio, which Business Insider valued at a whopping $100 million.

Musk’s first major piece of Bel Air real estate was purchased back in 2012 for a cool $17 million. The industrialist lived in the colonial-style mansion with his sons. At 20,248 square feet, the multi-winged mansion is a sight to behold. In June 2020, Musk sold the estate for $29 million.

In Oct. 2013, Musk purchased a $6.75 million home on the same Bel Air street. He used the home as a private school for his children, calling it “a little schoolhouse on the prairie, except in Bel Air on a golf course” in a 2015 Vogue interview. Musk sold the home in Oct. 2020 for $7 million.

Over the next three years, Musk purchased another three L.A. mansions, one valued at $20 million and another at $24.25 million. The third mansion was purchased for $4.3 million.

In 2017, Musk purchased another mansion in the area that was estimated at $4.2 million. All four homes were sold in 2020 for a whopping $62.5 million.

Separately, Musk owned a “boomerang-shaped house” in Brentwood, California, with his ex-wife Talulah Riley. The couple purchased the home in 2014 for $3.7 million and sold the home in 2019 for $4 million.

Purchased in 2017 for $23.4 million, Musk also owned a 16,000 square-foot Mediterranean-style mansion in Hillsborough, California. The industrialist put the home on the market in 2020 for $35 million, but has struggled to find a buyer.
