Agent Biography

Ian Katz
Ian Katz is best known for providing his clients a fully integrated advisory experience at every step of their buying or selling journey. He starts by listening to their unique needs and then applies his deep understanding of the market and strong financial acumen to make the best recommendations possible. Ian understands that real estate is both an emotional and financial decision and combines his strong interpersonal skills and analytical thinking to unlock the most value for his clients.
Ian takes great pride in serving as a lifelong resource for his clients, striving to create long-term client satisfaction— well beyond the initial transaction. With a commitment to transparency, Ian evaluates each property the same way he would for his own family, identifying the opportunities, pitfalls, and overall investment quality.
Ian considers his career in real estate to be a continuation of his family’s legacy. He was inspired by his grandparents who became real estate investors after immigrating from Poland in the 1940s. After a successful career in finance at BlackRock, Ian’s desire to create more authentic relationships led him back to his roots and re-ignited his passion for real estate. After becoming one of New York’s most accomplished independent brokers as leader of Ian K. Katz Residential LLC, Ian moved his business to Compass.
When Ian’s not fulfilling client dreams, he enjoys spending time with his wife, two sons and rescue dog Bailey. He is passionate about investing and wine tasting, especially pinot noir. He and his wife love all genres of music— he is a drummer, and his wife is a classically-trained flutist.
Client Testimonials
Ian worked very closely with us on our purchase of a coop on the UWS. We were consistently impressed with Ian’s professionalism, his in-depth knowledge of the NYC real estate market, meticulous attention to detail in preparing the board package & above all, his persistence in getting the deal to the finish line. Ian went above & beyond our expectations in helping us find our perfect home.
Ian made sure to advise me on all of the small details I missed in each apartment, and is smart enough recognize when an apartment's online listing isn't a fit for my own goals. When I finally decided on an apartment, Ian coached me through every step of the way to ensure I had a flawless board package. I'm extremely grateful for his help, his attention to detail, and responsiveness throughout. He made the entire stressful process manageable.
I have worked with Ian on two past purchases and one sale in seven years and have recommended him to others as well. Unlike most other agents, he will always offer his honest opinion backed by experience and data. While other agents will happily agree to everything you show interest in to make a deal, Ian will always play the devil's advocate and actually work in your interest. Always candid and patient, Ian brings much needed professionalism to the world of real estate transactions.
My wife and I hired Ian to sell our co-op apartment on the Upper East Side. Ian has an excellent working style and is extremely focused and thorough. He does what he says he is going to do. He follows through, follows up and keeps in constant communication throughout the process. In the end, we received the purchase price we had hoped for and Ian was a big reason why.
We recently completed a purchase with Ian, and of all the people involved in the process, he proved to be the most trustworthy, professional, and genuine. His expertise is amazing, and his willingness to help is infinite. I trust him blindly and would recommend him without hesitation.
Ian's background work and canvassing made our first day of apartment viewings wildly productive. In fact, I ended up purchasing the second apartment we viewed, which I fell in love with on the spot. Ian was thorough in showing me numerous apartments beyond the one I chose, which only made my decision easier and my mindset stronger.
I was extremely happy with Ian's exceptional and detailed level of service, and his personable, can-do style of professionalism. He skillfully helped me sell my co-op apartment in Midtown and then found me a great new condominium just up the street.

I've worked with Ian on two purchases, one sale, and managing a rental property. I highly recommend him for anyone in the NY area who is looking for an agent.

All of my transactions have had good outcomes, and I attribute most of that to Ian.
Ian did a great job in working with us leasing our property in NYC. Once it came time for us to sell the condominium, he was very good at implementing a successful strategy for us to maximize our value and working through the challenges of selling to a foreign buyer.
If I could give Ian Katz six stars, I absolutely would. His breadth and depth of knowledge gave us the piece of mind to make educated decisions, and there was no question too big or too small.

Ian was tireless in helping me find a wonderful new home. I was new to the process of buying a co-op and he walked me through every step of the way in great detail. It was a tough market but with his expertise and guidance, I found a great place that I truly love and plan on staying in for a long time.
After many negative and mediocre experiences with real-estate brokers, Ian proved to be exceptionally good. Unlike most others I worked with, he truly adds value beyond access to his database - expert opinion, advice and guidance. Ian would be my first choice with any future real-estate search.
Ian is an expert on the NYC market and makes an effort to know his clients' tastes and preferences so that every unit he shows fits into that criteria and does not waste his clients' time. In addition, Ian has been a great resource and advisor even after the transaction. I highly recommend Ian for an efficient and customized experience.
Working with Ian was an amazing experience. Ian is very prompt, responsive and made the process very easy for a first time buyer. Ian has an encyclopedic knowledge of all the ins and outs of the real estate market. More importantly, Ian fought for a good price for the place I was buying and could read the other party very well.
Ian recently helped my fiancé sell his apartment while also helping us buy our first home together. Ian helped us with the whole process from start to finish. He assisted us to make sure our old place was staged beautifully for prospective buyers and being very conscious of our WFH schedules. Simultaneously also scheduling viewings for homes for us to look at and always being available for calls since he could not attend them due to covid restrictions. Ian also helped to walk us through all of the paperwork and helped to make sure our move from one place to the other was as easy as possible.
