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 Co-op
"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 Co-op
"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. Additionally, she and her entire team are a true delight to work with and to be around.
Victoria, Buyer of an Upper West Side Coop & Seller of a West Village Co-op
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 CoOp board. Isil and Isabel became trusted allies in what we’ve learned is never an easy process. 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 counselo. 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. Isil is that agent and we cannot recommend her highly enough.
Michael & Kristin, Buyers of a Tribeca Condo
Anna, Buyer & Seller of Boerum Hill and Tribeca Condos
"Isil is savvy, incredibly reliable and dedicated, and took care of all the ins and outs of our apartment sale: from the major aspects, like having a implementing an aesthetic vision the space -- suggesting paint colors, rearranging our furniture, even staging it with contemporary decor of their own -- and marketing the heck out of it, to the minor coordination and scheduling details. We trust them both implicitly and always felt we (and our apartment) were in great, professional hands."
Amanda & Jason, Sellers of a tMurray Hill Co-op
"I've worked with Isil on a number of real estate transactions. Our first
time working together was a complicated transaction involving the rental
and subsequent sale of my apartment. We received an excellent price very
quickly. Isil is meticulously thorough, professional, and detail-oriented,
as well as sensitive to the needs of all parties involved."
