Elon Musk, the 2nd-richest man in the world, told Twitter he lives in a rented home that costs $50,000

• Elon Musk, the world's second- richest man, told Twitter he rented a $50,000 house in Texas.
• He's speculated to be living in a prefabricated home made by the housing startup Boxabl.
• The billionaire appears to be keeping a promise he made in May last year to "own no house."

Tesla CEO Elon Musk – the world's second-richest man, with a net worth of about $185 billion said in a tweet in June that he rented a home in Boca Chica, Texas, that costs $50,000.

On Thursday, Musk provided some more context about his housing situation. In response to a tweet showcasing a prefabricated home by the housing startup Boxabl, Musk wrote, "I do live in a $50k house, but not this specific one."

Teslarati, a media company that follows Tesla news, reported last week that it had received a tip that Musk's home was a Boxabl Casita, a 375-square-foot house with a kitchen, a bedroom, and a bathroom that starts at $49,500.

In November, Boxabl posted a video of a unit it was building in Boca Chica. The home was for a "top- secret customer," the company said. It had a poster of a Falcon 9, a partially reusable rocket built by Musk's SpaceX, on its door.

Boxabl, based in Las Vegas, aims to mass-produce low-cost housing. It creates homes that are delivered in a box and can be set up in a day.

Musk appears to be keeping a promise he made in a tweet in May 2020 to "own no house." Weeks later, five of his homes were listed for sale on Zillow. In late December, the Los Angeles Times reported that Musk had sold three of his adjacent mansions in Bel Air for a combined $40.9 million.

The SpaceX CEO said in June that he had only one house left in the San Francisco Bay Area that he rented out for events and was waiting to sell. It "needs to go to a large family who will live there," he said, because "it's a special place."

Boxabl and a representative for Musk did not immediately reply to Insider's requests for comments for this story.
