The billionaire Elon Musk appears to have downsized in a big way. His primary residence where he is spending much of his time is a $50,000 property he is renting from his private rocket company, SpaceX. 

Sticking to his motive “live below your means” to focus on his Mars voyage, Musk is now cutting his need for a spacious and fancy dwelling with a small regular hotel-room-size prefab after selling much of his real estate assets in the last year, and listing his final house earlier this month, reports the NYPost.

Announcing his new home earlier in June, Musk seemed to pretty much enjoy his humble decision. 

“My primary home is literally a ~$50k house in Boca Chica / Starbase that I rent from SpaceX. It’s kinda awesome though,” he wrote. “Only house I own is the events house in the Bay Area. If I sold it, the house would see less use, unless bought by a big family, which might happen some day.”

But it was not clear what type of cheap house he was living in. The only information is he rented the property from SpaceX on its launch site in Boca Chica, Texas. 

According to Teslarati, the website that updates Tesla news, it projected that the place Musk was living in must be a prefabricated home produced by housing startup Boxabl, which could be around 375-square-foot in size. 

Based on a video about one of its model houses, it appeared that Musk’s current home is composed of nothing more than regular basics, including a living room, bathroom, bed, and kitchen, all constructed from a folded box. 

However, in a responding tweet, Musk confirmed that it was not the type of housing he was living in. “I do live in a $50k house, but not this specific one,” he wrote

Elon Musk has been selling most of his $100 million property portfolio to focus on his Mars expedition. It wasn’t until June 14 that he finally decided to bid farewell with his last mansion in San Francisco for $37.5M.

“I am selling almost all physical possessions. Will own no house,” he announced in a Tweet last year.
