Honesty, resourcefulness and deep market knowledge. That's Jim.


Jim has helped us find two homes. In the process we have gotten to know him well and recommend him without hesitation.


In a world too often marked by brokers who don't have their client's interests at heart, Jim stands apart as a considerate advocate.


Tireless and seasoned in a myriad of acquisition and disposition scenarios, Jim knows how to close deals and create opportunities even in today's tough climate.


Jim gets the job done with grace and certitude.

We have known Jim McMahon since 2007 when we were contacted by him after an inquiry about a home on Houlihan Lawrence's website. He helped us close on our first Co-op. He did such a great job guiding us through the process that we contacted him again to help us purchase our house we closed on in 2011.


The search for our perfect house was a much longer process because it took us almost 2 years and around 80 showings to finally decide on one. Jim was always patient with us and never pressured us in any way. He was always available to do a showing at any time to accommodate our busy schedules and always sent us requested comps very shortly after a visit, even late at night. Over the years working with Jim he has not only been a great agent but we would also consider him a friend. We will use him as our agent for every home we buy and would highly recommend him to anyone else looking for a home.

Eileen, New York

Jim McMahon was our agent for both selling our house and purchasing a coop apartment.


We had our house on the market with another agency for over a year with no success. The minute we signed with Jim we knew we had made the right decision.  Jim provided us with the right pricing, helped us stage the property, and assisted us with all the legal matters of dealing with a large city's bureauarcy. Our house sold in the allotted time and the closing, with Jim's assistance, went smoothly. When we were ready to purchase an apartment, Jim knew just what to show us. He was extremely helpful in negotiations and the final purchase price.

I cannot recommend Jim more highly. His professionalism and real estate knowledge were superb.

We chose Jim McMahon as our agent because from our first contact with him he was immediately responsive and completely attuned our needs. Throughout the entire process he was honest about his role and what he could provide as our agent for the purchase of our first home. As first time home buyers, he walked us step-by-step through the process and answered all of our questions thoroughly and patiently. With each property we viewed he was extremely prompt and accommodating of our schedules and gave us as much or as little input as we needed on each issue. Some issues we were firmly decided on from the start, others we had no clue about. Jim addressed both scenarios appropriately.


Upon viewing the first few properties together Jim knew exactly what we were looking for and addressed the remainder of the property viewings accordingly. When it came time to close on our home, it was as if Jim was buying the property with us. We felt safe knowing he was working on our behalf. The purchase of our first home couldn't have been a more positive experience. We recommend and will continue to recommend Jim to all of our family, friends, and even perfect strangers. And we plan on going back to him when we are in the market for a new home. Thanks for everything, Jim!

Thanks for taking care of the sale of my Mom’s apartment.  You made it very easy for me as I live on the west coast.  I really appreciate how fast you answered my questions and how you were on top of the whole cycle.  I would not hesitate to refer you to my friends and family!

Ann B, New Hampshire

I was a long distance seller and Jim provided so many services for me that went far above and beyond the normal expectations of a real estate broker, that I can't even begin to list them.  From providing referrals to contractors (and a really good one, at that!!!!) to handling all the inspections and access to workmen, he was always quick and available with great ideas and follow through.  His suggestions for prepping the house for sale were also right on the money. 


Jim demonstrated terrific knowledge of his market and confidence in his pricing and analysis of other properties.  And he was spot on, with the house selling higher than he had forecast and going under contract within a week of listing. 


I'm in a related industry in a different part of the country and in my business I work with real estate agents and brokers daily.  Jim is absolutely one of the best I've ever worked with and I wholeheartedly recommend him.  I wish I could move him up north to work with us. 


Feel free to ask Jim for my phone number and I'll give you more information on the phone.  Jim is the real deal.  Thank you so much, Jim.

We are definitely very satisfied and grateful for choosing Jim McMahon as our real estate agent, on 3 different occasions. Jim worked with us in the process of buying our two last apartments and selling one of them. We could rely on Jim 100% with the stressful decision of putting our apartment on the market and buying a place that suits our needs. We were very concerned with the current sluggish housing market, but thanks to Jim we had a smooth process and peace of mind.
            Jim is a very dedicated agent who is always reachable by email or phone. He provided us with continuous feedback and updates and his recommendation showed his vast knowledge of the market. Jim is also very professional and respectful of the rules and boundaries for real estate agents. Jim is a hard worker and passionate about what he does.

It has been a great pleasure working with Jim and we highly recommend him.
Thanks Jim once again
we appreciate your support

Jim is a fantastic realtor. We moved from the city to the suburbs and were car-less and clueless. He provided great information on the neighborhoods and was very accommodating with our work and transit schedules. The last thing you want is to feel like you are inconveniencing your realtor. We found a fantastic home and are very happy!

Just a note to thank you for the consistently professional and efficient manner in which you dealt with my life changing, seemingly stressful situation and that you helped to remain a smooth transition.

            Your prompt, more than perfect timing was a breeze of fresh air. My definite requests were not a high challenge for you and a great deal of satisfaction to me.

            Your sound advice and calm, friendly approach was necessary in order to achieve the ultimate result that is my new home.

            Your 24/7 availability and the professional relationship that continues after reaching my dream home is more than comforting,

We were first time home buyers and had the good fortune to be referred to Jim due to his experience and deep knowledge of the area in which we wished to buy.  Jim was a pleasure to work with and really made the process a great experience for us.  From showing us numerous properties to negotiating price and closing on our house, Jim gave us guidance every step of the way.  He was also able to refer us to a number of great people in the area such as attorneys, inspectors, and insurance brokers.

Jim is a true professional and was always quick to respond to any questions or concerns we had.  He has become a friend to us over the time we worked together.  He is honest, hardworking and very knowledgeable - we would highly recommend him to anyone with real estate needs.

I happened to meet Jim McMahon at an Open House in Bronxville, NY in 2012. Although I met other agents at other Open Houses, I was immediately impressed with Jim's friendliness and knowledge of Co-ops in Westchester County so I decided to keep in contact with him. Two years later, after numerous showings and lots of advice, Jim was by my side when I closed on my first Co-op. Since then, I have recommended Jim to friends and colleagues, and I will definitely ask him to represent me when I decide to purchase my first home in a few years.

Having purchased our first home with Jim's help we particularly sought him out when it came time to sell.  In both transactions my wife and I were so impressed, frankly astounded, by the effort, and commitment that Jim made to our transactions and our property.  In both cases we exceeded our expectations and the outcomes were truly the best possible in our given market and time frame.  We have recomended Jim to several people and I wouldn't hesitate to work with him again.  Jim is a high quality and valuable individual.  I have met very few people with his level of dedication and professionalism.

Jim was the agent who helped us to sell our coop in the Fleetwood. He is a very knowledgeable expert in the subject matter of real estate, with very high ethics standards. Jim professionally handled all the issues during the sale and advised us, always protecting our best interests. You do not need to make multiple calls or wait for hours or days to get a response to your concerns - Jim gets back to you in minutes.  We ended up selling our coop at a significantly higher price than the average unit on the market in the area at that time. Great agent, if we had to do it  again we would go to Jim. Thank you!

"Jim was a great resources when we sold our place. Thorough, diligent, and always available. I've recommended him to my personal friends and I recommend him to you."

We chose Jim for our first home purchase because he came highly recommended by our friends, so we knew we could trust him. Jim proved to be a wonderful listener and understood what  we were looking for in a home which was evident in the listings he showed us. He didn't waste our time trying to convince us to purchase what we didn't feel comfortable with (like some other pushy realtors). Jim was a true advocate for us and our family, he would answer our calls, emails and questions quickly. When it came time to sell our home (after living in it for 9 years) we  knew there was only one realtor that we could trust to give us the best advice to sell it quickly. Jim was there at every open house and every showing. He gave us the best pricing advice that helped us sell it in 3 months in a very difficult market. He is honest, motivated and a pleasure to be around ..... You can't go wrong.

Jim was referred to me by a friend in Westchester when I needed help selling my mother's apartment.
My friend knew that Jim had done several sales within the building and that he knew the neighborhood particularly well.
What a welcome relief.

The first time we met, I knew immediately that the sale would go smoothly.
Jim knew just what I needed to do to ready the apartment for the sale; and he determined a crisp asking price.
He directed each step of the process with care, patience, and expertise, guiding both the negotiations and the co-op board process.
He also referred me to a local attorney.
Most welcome was the fact that he was always available to answer questions and offer advice.

I would happily recommend Jim to anyone in Westchester who is looking for a knowledgeable, friendly, reliable broker to facilitate either the buying or selling process.
