Meet Kim Kardashian's Most Trusted Realtor, Who Went From Working in a Mailroom to Selling Million-Dollar Homes

Finalizing the sale of Kim Kardashian West and Kanye West's $17.8 million Bel Air mansion that appears more like a high-end art gallery than a home is just another day at work for Josh Altman.

The Los Angeles-based real estate agent has been Kardashian West's go-to realtor for nearly a decade now, and has experienced a parallel rise to stardom and prestige in his industry. Altman and his brother Matt run their own real estate group — which recently partnered with Douglas Elliman, a nationwide real estate company — and sell $400 million in real estate each year. They serve a wide range of buyers — particularly those in the high-end, luxury market dominated by celebrities, athletes, tech moguls and executives in Los Angeles.

"We live by the 'ready, fire, aim' mentality, as opposed to 'ready, aim, fire,'" Altman told Money in a recent interview. "We've now trained ourselves to recognize opportunities when they're in front of us, no matter what it is, whether selling houses, or anything. It's really about taking a shot, not thinking twice."

Altman used that tactic while working on an off-market sale for the Kardashin West mansion earlier this year, strategically showing it to high-end buyers who would fit with its unique aesthetic. Altman showed Marion Acton, a Ukrainian philanthropist interested in starting a music career, the home with a private tour from Kardashian West herself. It was sold.

“Kim is so savvy when it comes to real estate,” Altman told Money last month when the home sold. “This is not her first house, this is not the first time she knocked it out of the park, because she constantly does that on every single property she buys. She knows what she’s doing, so I sit back and listen.”

What makes Altman so in touch with his celebrity clients is that he is one himself. In addition to his rise in the industry, he has starred in Bravo's Million Dollar Listing Los Angeles for several years now. That status, Altman says, helps him better serve and identify with his high-income clients. "We live in the neighborhoods where we sell to, we drive the cars our clients drive, we wear the watches our clients wear," Altman said. "We live and breathe what we put out there, and we're not just TV personalities."

Having a similar lifestyle to his clients makes him more trustworthy, Altman says, and helps them understand the typical needs of celebrity real estate like privacy. Throughout his conversations with Money, Altman repeatedly said he and his brother ensure they treat their client's money and time like it was their own.

But it wasn't an easy path for the Altman brothers to get to where they are today. After moving out to Los Angeles, Altman started in the mailroom of a music management company and used half of his paycheck to pay for meals or coffees with managers he admired to learn from them. Eventually, Altman found success in flipping homes before the mortgage crisis and economy collapsed in 2007.

"We lost everything," Altman said. "We were millionaires by 26, then flat broke by 26 and a half."

During that difficult year, Altman said he learned his biggest lessons. As he did years earlier, he spoke to everyone they knew in the industry, gathered any advice they could and realized perhaps their greatest strengths in the industry were in how they developed relationships with others. That's how the Altman brothers went on to represent big names like Kardashian West and expand their operation into something they now say is close to a concierge service.

Now, Altman sells everything from starter homes to $100 million mansions and hasn't looked back.

“When I look back at the ups and downs, there’s going to be a lot of mistakes anyone is going to make,” Altman said. “The most telling part is how they bounce back.”
