What is REALM?

REALM IS an exclusive, personally vetted membership of the top 1% of real estate professionals from 100+ brands worldwide.
REALM IS a lifestyle-based matching platform that focuses on specific lifestyle interests rather than simple search criteria.


And What Is the Realm Proprietary Platform?

REALM’s collaborative matching platform allows REALM Members to apply hundreds of curated lifestyle tags to each of their listings.

A proprietary combination of third-party lifestyle data sources matches these tags with the nearly 300,000 HNW REALM Member clients worldwide and scores them based on relevance. Collaboration between the individual  REALM members is then initiated on high matches to gauge property interest.

How can REALM help you find a home or help you sell your home quicker?
