REALM, the invitation-only global membership organization for top luxury real estate professionals, has announced the addition of a multi-office contingent from Berkshire Hathaway HomeServices Spain and Dubai’s Castilion Estates. This expansion deepens REALM’s footprint in two of the world’s most active wealth migration corridors, underscoring its position as the definitive community for elite advisors.
The Spanish contingent, led by CEO Bruno Rabassa, covers Marbella, the Costa del Sol, Mallorca, and the Costa Blanca. Spain has emerged as a leading destination for internationally mobile wealth in Europe, making this a strategic addition. In Dubai, Castilion Estates, led by CEO Mungi Adlan, operates at the center of a major hub for ultra-high-net-worth relocation. Both markets are critical in the current global movement of private capital.
The timing aligns with REALM’s recent white paper, “The Borderless Decade,” which highlights that ultra-high-net-worth capital is moving across borders at an unprecedented scale. The advisors who succeed will be those connected to this movement before it becomes a listing. Spain and Dubai are prime destinations for this capital flow.
“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.”
Bruno Rabassa, CEO of Berkshire Hathaway HomeServices Spain, explained the rationale: “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.”
Mungi Adlan, CEO of Castilion Estates, echoed the sentiment: “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 brand-agnostic, invitation-only model, where over 150 competing brokerage brands participate side by side. The community now includes approximately 600 advisors across 23 countries and more than 40 U.S. states, collectively representing over $50 billion in annual sales. This network effect is supported by proprietary REALM Match technology and REALM Intelligence powered by Scoop.
For business leaders and industry observers, this expansion signals the increasing importance of cross-border connections in the luxury real estate sector. As global wealth becomes more mobile, advisors and firms that are part of such networks are better positioned to serve their clients’ evolving needs. The addition of Spain and Dubai strengthens REALM’s ability to facilitate these connections, potentially influencing how luxury real estate is bought and sold worldwide.
