Elon Musk is apparently following through on his pledge to sell off his entire $100 million real-estate portfolio.

The cofounder of electric automaker Tesla said that he plans to sell “almost all physical possessions” and “own no house” in a tweet May 1. A total of seven of Musk’s homes have since appeared on Zillow as “for sale by owner.”

The listings are a stunning reversal of Musk’s real-estate strategy to date; the billionaire spent years buying up adjacent mansions in Los Angeles’ swanky Bel Air neighborhood. During a recent interview on “The Joe Rogan Experience” podcast, Musk explained that he’d purchased neighboring properties because of privacy concerns, including people trying to reach his primary home by climbing over walls.

All told, Musk and companies associated with him own at least seven homes worth over $100 million, Business Insider previously reported.

Musk used the house as a private school for his children. And in a 2015 interview with Vogue, the billionaire CEO described it as "like a little schoolhouse on the prairie, except in Bel Air on a golf course."

Musk later purchased two more on Bel Air mansions on an adjacent street — another ranch house for $20 million in July 2015 and an unfinished mansion for $24.25 million in 2016.

Two years later, Musk reportedly bought another mansion next door to those. The property — a colonial-style, two-story home built with a white brick facade — is estimated to be worth $4.2 million. These are part of a group of four homes listed for a collective $62.5 million on Zillow on May 13.

Musk had bought yet another Los Angeles mansion for $4.3 million in July 2015, but apparently didn't maintain it well. In December, the Wall Street Journal described this property as "unkempt, with a scruffy, bush-filled front yard, a stained glass window, a clay rabbit and dead plants in pots by the front door."

Neighbors also told the Journal in December that it didn't appear anyone was living in this house full-time.

Though Musk has previously said that he sleeps on a couch or on the floor of a conference room in Tesla's Fremont, California, headquarters during busy production periods, he also owns another estate nearby.

Located in the ritzy Bay Area suburb of Hillsborough, the 100-year-old, 16,000-square-foot Mediterranean-style mansion boasts 10 bedrooms, bay views, hiking trails, and a ballroom. Musk bought it for $23.4 million in June 2017, but just listed it on Zillow for $35 million.

The tech mogul also previously owned this "boomerang-shaped house" in Brentwood, California, about 15 miles northwest of downtown Los Angeles with his ex-wife Talulah Riley. The former couple paid just under $3.7 million for it in 2014, per the Variety-owned real-estate site Dirt.
