The invitation-only luxury real estate network REALM has announced the addition of a multi-office contingent from Berkshire Hathaway HomeServices Spain and Dubai's Castilion Estates, deepening its presence in two of the world's most active wealth migration corridors. The move reflects the growing importance of cross-border connections for top-producing advisors as ultra-high-net-worth capital flows across borders at unprecedented scale.
The Spanish contingent, led by Chief Executive Officer Bruno Rabassa, will bring coordinated coverage across Spain's most sought-after coastal markets, including Marbella, the Costa del Sol, Mallorca, and the Costa Blanca. This expansion comes at a time when Spain has emerged as one of Europe's leading destinations for internationally mobile wealth. In Dubai, Castilion Estates, under the leadership of Chief Executive Officer Mungi Adlan, operates at the center of what has become a major magnet for ultra-high-net-worth relocation.
The timing of these additions is significant, aligning with the findings of REALM's recent white paper, The Borderless Decade, which documents how global private capital is moving across borders in ways the luxury property market has never seen. The report emphasizes that advisors who succeed in this decade will be those connected to this movement before it becomes a listing. Spain and Dubai are key destinations for this capital flow.
REALM founder and CEO Julie Faupel highlighted the strategic importance of these additions: "The world's wealth is moving, and REALM was built to move with it. 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."
Bruno Rabassa, CEO of Berkshire Hathaway HomeServices Spain, explained the rationale for joining: "Our clients arrive in Spain from every corner of the world, and they expect us to know their world before they land. REALM connects us to the advisors, the intelligence, and the relationships behind that movement. It was the clear next step for our organization." Similarly, Mungi Adlan noted, "Dubai is where global wealth is choosing to live, and REALM is where the advisors serving that wealth choose to belong. 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 is driven by its unique position as a brand-agnostic, invitation-only membership that includes more than 150 competing brokerage brands participating side by side. This network effect is something no single brand can replicate. The community now numbers approximately 600 advisors across 23 countries and more than 40 U.S. states, collectively representing over $50 billion in annual sales. Members are supported by proprietary REALM Match technology and REALM Intelligence powered by Scoop.
These additions underscore how the luxury real estate industry is adapting to the realities of a globalized clientele. For advisors and their clients, being part of a network that spans key markets like Spain and Dubai provides a competitive edge in serving the needs of internationally mobile wealth. As the market continues to evolve, such connections are likely to become even more critical for success.
