In a city synonymous with sprawl, ambition, and soaring rents, few real estate players stand out for both scale and conscience. But brothers Nathan, Michael, and Joshua Kadisha are charting a new path in Los Angeles, one that is rooted in a deep personal commitment to problem-solving, sustainability, and giving back to the city that gave them everything.
Born and raised in Los Angeles, the Kadisha brothers grew up with a front-row seat to the importance of entrepreneurial drive and civic responsibility. Their family’s legacy includes early founding investments in Qualcomm and long-standing involvement in real estate and technology. But for the three brothers, now fully embarked on their own path, success isn’t measured solely in units acquired or deals closed; it’s about making a real difference in their community by taking on LA’s growing housing crisis.
In a July 2025 story, The Los Angeles Times outlined how decades of bad policy decisions led LA to become the “epicenter of America’s homeless crisis.” But while the factors that led to this disaster might be complicated, the root cause, according to the Times, has always simply been a lack of affordable housing. And that’s exactly the problem the Kadisha brothers are working to solve.
In 2016, the brothers launched K3 Holdings, a real estate investment firm that would become a centerpiece of the Kadisha Family Office’s long-term strategy. Their mission: to breathe new life into underutilized multifamily properties while expanding access to income-supported housing in Los Angeles. To achieve that lofty goal, the brothers take a unique approach to acquisition and development.
Michael describes K3 as a medium-scale investor that’s committed to renovating and improving its properties while also keeping them affordable, rather than using those improvements as a premise for massive rent hikes, as larger firms often do.
Together, the Kadisha brothers have grown K3’s portfolio exponentially, now owning and managing thousands of units across Los Angeles’ most rent-impacted neighborhoods. Their approach is clear-eyed and hands-on: acquire undervalued buildings, renovate them thoughtfully, and manage them with a sharp focus on the tenant experience, energy efficiency, and affordability. By taking control of day-to-day operations through their management company, Alpine LA Properties, and effectively implementing new technologies, K3 has dramatically improved its properties while keeping them accessible to Los Angeles’ working class.
“Affordable housing isn’t just about subsidized units,” Nathan adds. “It’s about creating sustainable options for middle-income Angelenos—nurses, teachers, hospitality workers—people who make the city run but can’t afford to live in it. We got into this business because we believe the housing shortage and affordability crisis can be addressed without destroying the fabric of these communities.”
That perspective has fueled K3’s commitment to expanding income-supported housing through public-private partnerships and long-term investment horizons. Another key to K3’s commitment to affordability is leveraging emerging technology to lower costs and increase operational efficiency.
Before joining his brother Nathan at K3, Michael was a tech investor with a knack for spotting practical applications for new innovations. Now, he brings that same mindset to finding impactful new technology to help manage K3’s properties as efficiently as possible.
“Working with Michael and the entire K3 Holdings team has been a pleasure,” says Juan Burgos, the CEO of Haven AI, an emerging platform used by firms like K3 to streamline resident services. “As AI transforms how real estate is owned and operated, K3 stands out as a true leader, not just adopting new technologies, but actively shaping how they’re applied to serve residents and operators alike. Their commitment to innovation while keeping residents at the center of every decision sets the standard for how technology can make quality housing more attainable.”
Haven’s AI-assisted property management software helps smooth out administrative tasks, while also allowing K3’s residents to get quicker, more reliable responses to tasks like work orders and maintenance requests. Meanwhile, through Alpine, Michael has led the charge on significant operational improvements and water and energy-efficiency upgrades across the K3 portfolio, helping promote environmental sustainability.
The brothers’ passion for equitable development doesn’t stop at the property line. For them, the mission is personal.
“We grew up here. We’re raising our families here. LA made us who we are, and we want LA to thrive so our children and our neighbors’ children can have the same opportunities that we had,” Michael says. “And that means making room for everyone.”
As the city looks for leaders who can bridge the gap between market-based solutions and social need, the Kadisha brothers offer a compelling blueprint: entrepreneurial, empathetic, and deeply rooted in the belief that home is where strong communities are born.
