Testimonial from Scott Fein
We had a fantastic experience with Elizabeth O’Neill as our real estate broker. Elizabeth provided so much value in every phase of this process:  Looking for an apartment, placing a bid on an apartment, and navigating through the sale and close.

Elizabeth was very cognizant of what we were looking for from a size, budget and location perspective. All apartments she suggested we view were all, to varying degrees, appealing to us. It was extremely important to us that we have a broker who listened to our needs and requirements in an apartment and show us apartments that were appropriate based on those criteria.

Elizabeth was a pleasure to work with throughout the whole apartment search process. She always impressed us with her knowledge of not only the neighborhoods in which we looked in, but also the specific apartment buildings and communities where these buildings were located. She developed a great repoire with all selling brokers we came into contact with during our search. We also valued her honest opinion of an apartment after we viewed it. She stayed very even keeled and was able to help us assess the pros and cons of this enormous decision.

Elizabeth was a great mentor and guide when it was time to put bids on apartments, always being honest as to what was a reasonable bid to place.

Elizabeth provided tremendous value after our bid was accepted as we moved into the buying process. Her knowledge and expertise was invaluable and really helped us stay sane. There are so many things to keep in mind once a bid is accepted and she was able to keep us on track with her superior project management skills. That, to us, was such a huge help.

Overall, Elizabeth has proven that she is extremely valuable from the second you call her to the second you close on an apartment. She knows and understands the timeline of events and that really played a huge role in our experience with her.
Testimonial from Matt Hodes

Elizabeth is an outstanding broker. She really worked with me to establish a clear understanding of my needs and my preferences, both with regard to location, style, quality and price. Thanks to her hard work settling on a place to live in NY was easy and quick.

Testimonial from Nirad Sharma

Elizabeth helped my wife and I find our apartment on the UES.. She was very helpful, patient and insightful. This was all the more noticeable as my wife was going through acute health issues at the time. Elizabeth was very patient with us, especially whenever we had to do last minute reschedules to accommodate my wife’s treatment. Our negotiations and closing were quick and completely uneventful. In general, all of our interactions were very professional and efficient. I would use Elizabeth again for my next transaction.

Testimonial from Lauren Hildenbrandt

Thank you for making this process enjoyable!  I love my new home and I can’t wait to get settle in.

Testimonial from Mary Walker

We have enjoyed working with you immensely.  You are so diligent, hard working, thorough, professional and also kind and generous.  It has been painless.

Testimonial from Ginger Lief

You were entirely responsible for my having a wonderful experience with the sale of my apartment.   I never expected anything going so easily and perfectly but you did it for me and I am so very grateful.  The first time we met, I opened my door and you came in bringing sunshine in my home immediately.  All your ideas for the sale were brilliant. You are an incredible person.  I feel so fortunate we met.

Testimonial from Richard Marshall

Thank you for your assistance in handling the listing/sale of my property. You did an outstanding job and did so with great efficiency and professionalism. And you helped me hit my deadline.  After having little to no action for nearly twelve months with another agent/firm, you organized a smart, targeted, and effective campaign that got my property in play for the right target audiences. Throughout, your instincts and advice were always helpful and your feedback and updates were timely and substantive. You were the best I’ve worked with and I just wanted you to know how much I appreciated and valued your efforts.

Testimonial from Mary Maguire

You were so wonderful to work with and very patient too with all my frustrations with the NY coop practices that I am not used to. I just loved working with you as did my girls.  I thank you too for your sweetness and generosity in working with Lauren and Danielle. They found apartments that suit them both, thanks to you!

Testimonial from Jenn and Jerry Bregman

In addition to finding us the perfect home, your guidance in the negotiations was invaluable. You expertly navigated and guided us in the back and forth deal points with the seller, and obtained for us a much better price than we had even hoped! The ease and facility of your handling of the logistics was welcome, refreshing and impressive, including the many inspections, the Board materials and related activities. We had dreaded that process from prior transactions, and you made it all painless. It was such a pleasure to work with you that we are recommending you to our friends in the New York area.

Testimonial from Ben Dattner

Elizabeth O’Neill is the rare real estate broker in New York City who combines deep knowledge with both friendliness and total integrity. She handled the listing and sale of my apartment with patience, skill, and good humor, and priced the apartment perfectly. Within one day of the first open house I had an accepted offer at full ask with an ideal buyer. I recommend her without any hesitance or reservation, and would be happy to speak with anyone anytime to answer questions or provide more information.

Testimonial from Josh Bazell

I am absolutely delighted to provide a testimonial for Elizabeth O’Neill, through whom I purchased my apartment on the Upper West.  At every stage of a complicated process, Ms. O’Neill was more than I ever could have hoped for as a real estate agent.  Her endless energy and her absolute trustworthiness and excellence of character, her excellent taste and clear thinking, and her ability to get every kind of thing done made the experience a pleasure.  I have found in Ms. O’Neill a friend, an ally, and a real estate agent I hope to work with for the rest of my life.

Testimonial from Johanna and John Socolow

We were so pleased that we selected Elizabeth to represent the sale of my mother’s apartment–our long time family home.  She priced it right from the get-go and not only did she secure multiple compelling offers within the first week, she also expertly negotiated on our behalf and had a keen understanding of which purchaser would be the best fit.  She handled everything for us, going above and beyond,  so it was effortless for my mom and our family.  She was always available to us and kept all of the family members abreast of developments each and every step of the way.  All the while she was a pleasure to work with and to be around.  We are so grateful and would recommend her without hesitation.
