Manhattan is my specialty: first-time buyers & those moving into Manhattan will benefit from my extensive knowledge of the different neighborhoods and my absolute enthusiasm for the job. My wide-ranging experience is also invaluable to overseas buyers and sellers.

First-time NYC buyers »

I'm always thrilled to sell an apartment in NYC to a first-time buyer. I know the city and the market so well that I can successfully place the first-time buyer in his/her ideal apartment and neighborhood. New York is a city of neighborhoods and I've lived in most of them; I understand the details of each, from schools to restaurants to transportation. I have the enthusiasm and energy to work with the first-time buyer to ensure he/she is as happy as I am to live in New York.

International clients »

International buyers & sellers can have complete confidence in my ability to understand their needs. I've worked with clients from the UK, Sweden, Mexico, Italy and South Africa to name a few, and I have strong ties to several ex-pat communities. I've traveled extensively and pride myself on my knowledge of international business & cultural mores.

Buyers moving to NYC »

Relocating to Manhattan can be an intimidating, stressful experience. Having to learn about different neighborhoods and school systems, let alone physically moving, can be overwhelming. I enjoy working with clients moving to Manhattan because I know Manhattan as well as anyone and I love to pass on that knowledge. I've lived here for 35 years, raised a family, worked, played and done charity work here. I've experienced life to the fullest here and I look forward to seeing my clients enjoy the city as much as I do. I can be especially helpful to customers with school-age children because I understand both the private & public systems so well.

Agent's personal statement

As a lifelong New Yorker who has lived, worked and sent my children to school in various zip codes throughout the City, I have developed vast but detailed information about neighborhoods, subway and bus routes, public and private schools, and comparable sales in nearby buildings and surrounding neighborhoods. My intimate knowledge of the City enables me to best prepare my customers for what can be a long, but nevertheless, rewarding process.


Originally trained as an educator, today, I am a Senior Vice President and Associate Broker at Corcoran. I employ the same skills I used in the classroom to simplify the myriad complexities of the real estate process to ensure that my buyers and sellers are equipped with the knowledge they need to best determine their ideal price, location, and type of home -- be it a co-op, condominium, rental property or townhouse. Just as I accommodated the diverse needs of my former students, I am able to tailor my research and approach to each of my clients, whether they are first-time buyers or sellers, seasoned New Yorkers, out-of-towners, foreign investors, or those looking to build their lives around their home.


Although I have completed hundreds of successful real estate transactions, I value the unique requests of each of my clients, and recognize that every purchase or sale is both a financial and emotional decision. That is why my relationship with my customers and clients is collaborative and my approach to real estate is proactive. I understand that my job extends beyond just showing apartments. I communicate with mortgage brokers to guarantee that mortgages are written in a timely manner, and I work with respective attorneys to ensure that all information is accurate and available. I collaborate with the managing agent to produce a board package that is both complete and easily understood and I leverage unique tools to market apartments in a way that best complements the property.


My endless energy, vast knowledge about New York City real estate, and unrelenting drive to guarantee that my buyers and sellers receive the price they desire and the property they love stem from a lifetime of experience as a resident of New York myself, and a dedicated love of real estate. It is my highly personal, tailor-made approach that enables the unique level of trust and loyalty that I share with my clients, and encourages the ultimate validation for any real estate professional – the repeat customer.

“Lynn advised me every step of the way during my co-op purchase. She was tremendously helpful in all regards, particularly with the Board package.”

Annamarie Z.

I feel that I was in really good hands working with Lynn, and I'd absolutely recommend her to friends or family. She really made me feel comfortable by being so available; if there was ever a time in which she couldn't answer a question right away, she always called back. Since I was a first-time buyer in Manhattan, and I was purchasing a property for my daughter, I was happy to have Lynn advising me every step of the way. She was a good advocate for me, and she kept my best interests at heart. When it came time to prepare the Board package, Lynn just asked me for the information she needed, then compiled the whole thing on her own. That was tremendously helpful, too, like everything Lynn did.

Lynn is terrific. Lynn helped me purchase two co-ops in New York City, the first on the Upper East Side and the second in Chelsea. Lynn's listening skills and patience are what set her apart from other agents. She always paid close attention to what I said which enabled her to understand my tastes, wants and needs. She quickly learned my likes and dislikes, as well as the issues on which I was willing to give, and those issues on which I was not. I'll never use another agent in New York City.
“Lynn's ability to profile her clients is outstanding - she really loves working for them.”

Lynn's approach to working with her clients is very comprehensive. The first time I purchased with her, she was able to infer and subsequently sum up my likes and dislikes after only three or four viewings. She combined what I had told her with my reactions to different properties to develop a complete understanding of my preferences, so she didn't show me unsuitable properties after that. The second time I worked with her, she took me to only three or four places, and I could've purchased any of them. This was three years later, and she still remembered my preferences. Her ability to profile her clients is outstanding. Lynn's expertise doesn't stop there - she also has a great ability to work with other brokers and lawyers in order to close a deal. The entire time, she never acts like she needs to close the deal or earn a commission, but instead, it's apparent that she genuinely likes her work and loves to serve her clients. I've recommended Lynn to a number of friends, and I would do it again, no questions asked. She's very pleasant to work with.

As a realtor myself, and having worked with Lynn to both buy and sell a condo in NYC, I can speak to the fact that Lynn is a fabulous real estate agent. She is extremely knowledgeable about the city, it's various neighborhoods and the condominium market. Not only is Lynn extremely trustworthy and responsive, but she is also a joy to work with. I had fun working with Lynn because of her contagious enthusiasm. I've already referred her to others who are considering buying or selling in New York City.
“Lynn is extremely passionate about helping her clients achieve their goals.”

I worked with Lynn to buy a condominium in Hell's Kitchen, and to subsequently rent that apartment. From working with Lynn, it is obvious that she is extremely passionate about her work. She has a unique personality, is relentless and was a perfect fit for my family. Lynn is terrific and worked diligently to get the job done. I wouldn't hesitate to recommend Lynn to anyone.
“Lynn made the process stress free. She is assertive, responsive, and caring.”

Lynn is everything that you could want in a real estate agent. She is assertive, responsive, knowledgeable and caring. Lynn helped me buy my one bedroom co-op on the Upper West Side and now she is in the process of helping sell it as my family is leaving New York City. Throughout my experience working with Lynn, I was always confident that she had my family's best interests in mind. Lynn respected our needs and skillfully guided us through the negotiations. With her help, the transaction went smoothly and was as stress-free as possible. Overall, my family had a wonderful experience working with Lynn. Without a doubt, I would recommend Lynn to anyone considering buying or selling a home in Manhattan because Lynn gets the job done and done right.

Lynn was great to work with. She was very patient and after viewing several apartments she had a good understanding of what I was looking for. She has a very strong knowledge of the market and was able to offer valuable advice in the negotiating process. Ultimately, she helped me purchase a co-op on the Upper West Side.
“Lynn is easily the best agent with whom I've worked.”

When I decided to begin looking to purchase a co-op on the Upper West Side, I interviewed and briefly worked with a few agents other than Lynn. After meeting Lynn, I quickly realized that she was easily the best. I was impressed at the vast amount of information she possessed for specific properties and her businesslike approach to finding my home. Lynn analyzed the positives and negatives of each property and understood how to run a financial analysis. My daughter-in-law emphasized Lynn's broad knowledge base when she recommended her to me and she could not have been more right. Lynn was extremely professional, sensitive to my needs and mindful of my time. However, it is Lynn's generosity and kindness that makes her truly special. Lynn is outstanding and working with her was a treat.
“A professional and knowledgeable broker.”

We worked with Lynn to sell an investment property on the Upper East Side of Manhattan. During the process, we decided not to sell the apartment because of the deteriorating market conditions. Lynn quickly shifted her focus from the sales market to the rental market and found us a suitable renter. I've worked with many real estate agents in the past and with some, I've had to do most of the research; others have been pushy or not very knowledgeable. Unlike those agents, Lynn did her homework, had an excellent understanding of the market and was never pushy. I would highly recommend Lynn to a friend or family member because she is very professional and knowledgeable. Lynn is amazing.

I began working with Lynn in January 2006 when she helped me buy a co-op apartment on the Upper East Side. My family had been renting and we decided that, not only was it a good time to buy, but we also needed more space. Lynn is extremely knowledgeable about the properties in the Upper East Side and knows what co-op boards look for in an applicant. She understands how to work the co-op approval process from beginning to end, and in this regard she made what could be a very challenging process very easy for us. Lynn is not your typical agent because she is genuinely interested in more than simply selling a home. Rather she takes the time to actually get to know you. She still periodically calls me to say hello and to ask about my family. I would absolutely recommend Lynn to anyone.
“Lynn is intelligent, enthusiastic and great at sensing opportunities.”

Lynn Kellert of the Corcoran Group was instrumental in my purchase of a pre-war co-op apartment on the Upper East Side when we changed our primary residence from Long Island to the city five years ago. Though I had known Lynn for many years, working with her showed me her professional side reflecting enthusiasm, tenacity and intelligence. She saw opportunities, jumped in and negotiated well. Lynn has a keen understanding of the negotiating process, knows the importance of a perfect and complete board package, and gives careful consideration to board approval. The apartment we bought already had an accepted offer, but with questionable board approval. Lynn sensed an opportunity, worked quickly and caught the deal. Since I have been a broker for over 25 years on the North Shore of Long Island, I can appreciate a very strong broker. Lynn is smart, knowledgeable, effective and knows how to close a deal.
