About Rebecca

Rebecca Knaster is a seasoned Licensed Associate Real Estate Broker with nearly three decades of success helping clients buy and sell properties across New York City. Since 1997, she has built a stellar reputation at leading firms including The Corcoran Group, William Raveis, and Douglas Elliman, consistently earning top producer status and multimillion-dollar sales accolades, including Platinum Club recognition.

A native New Yorker, Rebecca brings deep knowledge of Manhattan’s diverse neighborhoods and a particular expertise in co-op and condo sales. Having lived in her own co-op for 36 years and sold nearly 200 apartments in The Connaught—where she is the building’s top-selling agent—she offers unmatched insight into navigating complex board approvals and buyer qualifications. Her experience also includes serving as a board director, further enhancing her clients’ understanding of the process.

Known for her sharp negotiation skills, creative marketing strategies, and keen design eye, Rebecca is a responsive, resourceful, and highly communicative advocate for her clients. Her ability to quickly position properties for maximum exposure and optimal price sets her apart.

Before entering real estate, Rebecca earned a B.F.A. from Pratt Institute and worked in the fast-paced industries of fashion, marketing, and advertising sales—experience that continues to inform her strategic approach.

Outside of real estate, Rebecca splits her time between Manhattan and East Hampton. An avid skier, cyclist, and hiker, she has explored slopes and trails across the U.S. and Europe. She’s also a passionate animal lover with over 30 years of experience rescuing and caring for Cocker Spaniels.

For expert guidance in NYC real estate, reach out to Rebecca—she’s ready to help you achieve your goals.
