Take a look inside Elon Musk's former house, a 'haunted mansion' where he once held a Gatsby-themed party

• Elon Musk said his San Francisco mansion was the "creepiest" house he's ever lived in.
• The billionaire detailed elaborate parties he'd thrown at the mansion during a podcast interview.

Elon Musk joked that he once lived in a "haunted mansion" and reminisced about elaborate parties he's thrown during a podcast earlier this August.

During the interview, Musk compared his former house in the Bay Area to the house from "The Shining."

"It is the creepiest house I've ever lived in," Musk said, referencing instances where he heard "strange sounds" and doors appeared to open and closed of their own accord.

"I see no actual evidence for ghosts, but that doesn't mean you can't get creeped out late at night," Musk joked during the podcast.

The house, which Musk sold in December for an estimated $30 million, is 16,000 square feet and has seven bedrooms, 9.5 bathrooms, and a pool.

Musk, the richest man in the world, initially bought the house in 2017 for about $23 million, according to the price history on Zillow.

The 47-acre property represents "one of the largest parcels of land" in San Francisco and dates back to about 1912, according to the old listing on Redfin.

The billionaire said some of his parties fed into the home's aesthetic, including a birthday party styled after "The Great Gatsby" that he held about four to five years ago.

"The parties are generally very high production value," Musk said, noting he prides himself on the elaborate set design and live action performers at the parties.

During the Gatsby party, Musk said they were forced to turn the music off after the local police were called at least four times to shut the party down.

The billionaire joked that his party irked his neighbors in Hillsborough, California, where the average home price is over $5.6 million and "everyone goes to bed at like 10 pm," he said.

Musk said he also held a party themed after the video game "Castlevania" at the mansion.

The billionaire has been known to throw intricate parties. Musk has said he ran a night club out of a college frat house in the 90s to help pay rent and university expenses.

Earlier this year, the Tesla CEO held a "Cyber Rodeo"party to debut the carmaker's new factory in Texas. The event featured a drone display, flashing blow-up cacti, and a Tesla hanging from the ceiling. The year before, he threw a 9,000-person rave at Tesla's Berlin factory.

During the podcast, Musk admitted it's been at least three years since he thrown a private party, in large part due to the pandemic.

Musk's San Francisco residence was the final home he sold last year after he vowed to sell all of his belongings to fund a colony on Mars. The billionaire pocketed about $130 million after selling his expansive real estate portfolio.

Since, Musk has said he lives in a "very small" 3-bedroom house in South Texas that is valued at about $45,000.
