Jennifer Jungun Sim

Jennifer Jungun Sim is a New York City–based real estate professional specializing in luxury residential sales, new development, and exclusive rental listings across Manhattan, with a strong focus on Tribeca, Hudson Yards, West Chelsea, the Upper West Side, and Battery Park City.

She brings extensive experience representing high-end condominiums, sponsor units, and new development properties, working closely with owners and developers to position listings strategically within Manhattan’s competitive luxury market. Jennifer is known for her precise pricing strategy, thoughtful marketing, and in-depth understanding of individual buildings and developments.

Before entering U.S. real estate, Jennifer built her career within Korea’s corporate environment, including experience with a global marketing subsidiary of Samsung Electronics and major Korean financial institutions. Having relocated to the United States over a decade ago while maintaining close professional ties with Korea, she offers a rare ability to bridge Korean clients’ expectations, communication styles, and decision-making processes with the realities of the New York real estate market.

Beyond individual transactions, Jennifer places a strong emphasis on building long-term relationships rather than one-time deals, guiding her clients with consistency, transparency, and a long-term perspective that supports their evolving real estate goals.

Fluent in English and Korean, she regularly works with both domestic and international clients, providing clear communication and hands-on support throughout complex New York real estate transactions.

Clients value Jennifer for her professionalism, responsiveness, and meticulous attention to detail from initial strategy through closing.
