Expansion across two of the world’s most active wealth migration corridors underscores REALM’s position as the definitive global community for the top-producing luxury advisor

July 2026 – REALM, the invitation-only global membership of the most accomplished professionals in luxury real estate, today announced the addition of a multi-office contingent from Berkshire Hathaway HomeServices Spain – spanning Marbella and the Costa del Sol, Mallorca, and the Costa Blanca – alongside Mungi Adlan, Chief Executive Officer of Castilion Estates in Dubai. Together, the additions deepen REALM’s footprint in two of the fastest-moving destinations for global private capital.

The Spanish contingent, led by Chief Executive Officer Bruno Rabassa, brings coordinated coverage across Spain’s most sought-after coastal markets at a moment when the country has emerged as one of Europe’s leading destinations for internationally mobile wealth. In Dubai, Castilion Estates operates at the center of what has become the world’s most consequential magnet for ultra-high-net-worth relocation.

The timing is not incidental. REALM’s recent white paper, The Borderless Decade, documented the defining dynamic of this market cycle: ultra-high-net-worth capital is in motion across borders at a scale the luxury property market has never seen, and the advisors who win this decade will be the ones connected to that movement before it becomes a listing. Spain and Dubai sit squarely on the map of where that capital is going.

“The world’s wealth is moving, and REALM was built to move with it,” said Julie Faupel, Founder and CEO of REALM. “When a contingent of this caliber joins from Spain in the same season as a leader like Mungi Adlan in Dubai, it’s not a coincidence – it’s confirmation. The most exceptional advisors in the world’s most dynamic markets are choosing the same institution, because they understand that their clients no longer live in one market. They live in motion.”

“Our clients arrive in Spain from every corner of the world, and they expect us to know their world before they land,” said Bruno Rabassa, CEO, Berkshire Hathaway HomeServices Spain. “REALM connects us to the advisors, the intelligence, and the relationships behind that movement. It was the clear next step for our organization.” 

“Dubai is where global wealth is choosing to live, and REALM is where the advisors serving that wealth choose to belong,” said Mungi Adlan, CEO, Castilion Estates. “Joining REALM places Castilion Estates inside a genuinely global community of peers – and places our clients inside a network that spans every market that matters to them.”

REALM’s growth continues to be driven by its singular position in the industry: a brand-agnostic, invitation-only membership in which more than 150 competing brokerage brands participate side by side – a network effect no single brand can replicate. The community now numbers approximately 600 advisors across 23 countries and more than 40 U.S. states, collectively representing more than $50 billion in annual sales, supported by proprietary REALM Match technology and REALM Intelligence powered by Scoop.
