Jennifer Sim

StreetEasy Professional Profile

Jennifer Jungun Sim is a New York City–based real estate professional specializing in luxury residential sales, new development, investment properties, and exclusive rental listings throughout Manhattan. Her experience spans many of the city’s most distinctive residential markets, including Tribeca, the West Village, Hudson Square, West Chelsea, Hudson Yards, the Upper West Side, and Battery Park City, as well as other prime Manhattan neighborhoods.

Jennifer brings extensive experience advising buyers, investors, owners, and developers across Manhattan’s residential market. Her work spans luxury condominiums, new developments, sponsor units, resale properties, and investment-focused acquisitions, with an emphasis on understanding not only neighborhood trends, but also the nuances of individual buildings and developments. She takes an analytical approach to pricing, carrying costs, rental potential, resale value, and long-term positioning, helping clients evaluate a property beyond the immediate transaction.

Her practice is highly advisory-driven, particularly for international clients navigating the complexities of the New York market. Jennifer works closely with Korean investors, high-net-worth individuals, and business owners seeking opportunities in Manhattan, providing hands-on guidance from initial market evaluation and property selection through negotiation, due diligence, closing, and ongoing ownership considerations.

Before entering U.S. real estate, Jennifer built her career in Korea’s corporate environment, including experience with a global marketing subsidiary of Samsung Electronics and Shinhan Bank, one of Korea’s major financial institutions. After relocating to the United States more than a decade ago, she has continued to maintain strong professional ties with Korea. This combination of experience gives her a distinctive understanding of Korean clients’ expectations, communication styles, decision-making processes, and approach to business, while helping them navigate the very different practices and realities of New York real estate.

Bilingual in English and Korean, Jennifer often serves as a bridge between her clients and the broader New York real estate ecosystem, working closely with developers, attorneys, lenders, property managers, and other professionals to help transactions move forward clearly and efficiently.

At the heart of Jennifer’s practice is a belief that real estate is about relationships, not simply transactions. Rather than viewing a closing as the end of her role, she strives to remain a long-term resource for her clients as their needs, investments, and real estate goals evolve over time.

Jennifer is known for her responsiveness, transparency, attention to detail, and hands-on approach, combining deep Manhattan market knowledge with a global perspective and a commitment to protecting her clients’ long-term interests.
