Isil Yildiz Team

Upper East Side, Upper West Side & Brownstone Brooklyn Specialists

The team has developed particular expertise in the Upper East Side, where they have built a strong presence in Carnegie Hill with more than a dozen listings on Park Avenue in recent years. They also have extensive experience throughout the Upper West Side, Tribeca, Gramercy, and Brownstone Brooklyn, including Brooklyn Heights, Park Slope, Cobble Hill, Carroll Gardens, Fort Greene, Clinton Hill, Bedford-Stuyvesant, and surrounding neighborhoods.

Co-op Expertise

Co-op transactions are unique to New York City and often involve considerations beyond the purchase contract itself. Financial requirements, board interviews, building policies, and unwritten norms can all influence the process. The Isil Yildiz Team has extensive experience guiding buyers and sellers through these complexities, from preparing a property for market to navigating board applications and approvals.

High-Impact Refresh Plan

Through our High-Impact Refresh Plan, we help sellers determine which strategic improvements will maximize value while minimizing unnecessary cost. From coordinating vendors and building approvals to overseeing painting, staging, photography, and marketing, they manage every detail with the goal of making the selling process as seamless as possible.

Strategic Advocacy

Before entering real estate, Isil practiced for six years as a white collar criminal defense and securities litigator after earning degrees from Yale University and The University of Texas School of Law. That background continues to shape the team's approach today, bringing analytical rigor, strategic negotiation, thoughtful deal structuring, meticulous attention to detail, and an unwavering commitment to integrity.  Frequently invited to speak on the New York City housing market, Isil has presented seminars for lenders, employers, and professional organizations on buying and selling real estate in New York City.

Testimonials

"Isil and her team helped us sell our parents' Upper East Side co-op. During the whole process, they worked tirelessly to prepare and price an apartment that was in serious disrepair as it had not been renovated in over 50 years. They expertly marketed the property to qualified buyers and worked closely with us through a successful negotiation that turned multiple lowball offers into an above-asking sale. Throughout the process, their advice on how to best prepare the apartment, how to negotiate with prospective buyers, and how to prepare for and navigate the co-op approval process created a deep trust for their judgment, skill, and understanding of the world of Upper East Side co-ops."

Thor and Andy, Sellers of a Park Avenue Coop

"Isil helped me to find my dream home in record time and then to navigate all of the red tape of NYC co-ops with ease. As an attorney dedicated to her clients, I am deeply grateful for Isil’s problem-solving attitude, her responsiveness and attention to detail, and the utmost professionalism with which she approaches every single step of the home-buying process."

Nina, buyer of an Upper West Side Coop

"Isil walked us through every step of the home buying process and consistently offered creative suggestions and advice. It's not easy these days to buy an apartment in Brooklyn, but Isil really helped guide us through it all. She really knows the market and understands how to make a deal. Isil also has an extensive network (mortgage agents, lawyers, architects, etc.) who are pros and were of great help to us. We cannot recommend her highly enough."  

David & Sarah, buyers of a Park Slope Condo

Since living in NYC, I have moved a few times and it's no exaggeration to say that Isil is by far the best realtor I have ever worked with. I worked with her for both buying and selling in two complicated co-op situations, and she made the process as stress free as possible. I always knew that she would advocate for me and had my best interest in mind. 

Victoria, Buyer of an Upper West Side Coop & Seller of a West Village Coop

When it came time to sell our (first) apartment of thirty years, we were a bit nervous and needed some good advice and counsel to help us navigate the current market and a Park Avenue Co-op board. Isil and Isabel became trusted allies. It may sound cliched but we felt their commitment to us was genuine and their guidance throughout; whether regarding pricing, staging and offers was always purposeful and sound. We would not hesitate to recommend them and we will definitely be calling them when we’re ready to sell again. 

Bill and Nina, Seller of. Upper East Side Co-op

Isil is, quite simply, a superb real estate agent. I was one of those people who wondered at the need for an agent; Isil proved herself invaluable throughout our process. She was an excellent advocate and counselor. Isil was able to negotiate on our behalf in a strong, yet productive, manner that consistently kept things moving forward -- especially when our transaction seemed at risk of stalling. Housing is, for nearly everyone, the largest and most significant financial decision that they will make in their lives; we should all want the smartest, most ethical, and effective professional to help with that decision.
