The rapaport team.
Josh and Katja Rapaport
Global Real Estate Advisors
Josh and Katja Rapaport advise clients on luxury residential and investment real estate throughout Telluride, Mountain Village, and beyond. Together, they built one of Telluride’s most respected independent real estate brokerages, closing over $585M million in sales, and are known for discretion, deep market knowledge, and long-term client relationships.
With decades of combined experience, Josh and Katja bring a thoughtful, advisory-driven approach to every engagement—guiding clients through complex decisions with clarity, strategic insight, and care. Their backgrounds in development, construction, ownership, and design inform a holistic perspective that extends well beyond the transaction itself.
After years of building their independent brokerage, Josh and Katja chose to align with Sotheby’s International Realty to expand their clients’ reach while remaining true to the highly personal way they work. Through this alignment, they serve clients not only locally, but also as global real estate advisors, connecting buyers and sellers to opportunities worldwide through a trusted international network.
Deeply rooted in the Telluride community, Josh and Katja are equally committed to giving back. Together, they co-founded the Telluride Animal Foundation, reflecting their shared belief that meaningful success includes stewardship, community involvement, and long-term impact.
