A Multi-Market Force
With over $20 million in deals currently sold (Q2 2025) and a growing portfolio of design-driven projects, Sarah Cotty continues to set a new standard in luxury real estate. Recognized as a top Williamsburg luxury broker, Sarah works closely with the top 1% of NYC and Florida’s wealthiest clients, helping manage and optimize their real estate portfolios to achieve exceptionally high returns. Based in New York and active throughout Florida, she brings a sharp eye, steady hand, and strategic mindset to every client interaction, from resale and new development to investment and relocation. Her work increasingly attracts wealth managers and high-net-worth advisors, creating a steady pipeline of qualified buyers and sellers and bringing significant capital into every market she serves.
NYC to Florida - and Everywhere in Between
Sarah’s work spans New York City’s most competitive markets, including Manhattan, Brooklyn, and Queens. She’s represented buyers and sellers across co-ops, condos, new developments and townhomes in neighborhoods like Tribeca, Chelsea, and the Upper East Side, while also actively growing her presence in Florida hot spots such as Miami, Fort Lauderdale, and Tampa.
Her multi-market fluency allows her to guide clients making big moves between New York and Florida, and advise on purchases that prioritize lifestyle, design, and long-term value. With a trusted network of referral partners in every state, Sarah ensures her clients receive expert, on-the-ground guidance wherever their next move takes them.
A Proven Leader in New Development
Sarah is especially focused on the future: new development. With multiple projects in the pipeline and more on the horizon, she works closely with developers to bring buildings to market with intention; pairing architectural vision with strategic positioning, pricing, and execution.
She’s particularly drawn to projects that blend elevated design with thoughtful function, bringing a buyer’s mindset and a marketer’s sensibility to the table. Her relationships with wealth managers, private bankers, and investor networks allow her to position projects in front of qualified, well-capitalized audiences from day one.
