Patient & Understanding

Our experience with Ann Marie was outstanding. Ann Marie helped us with the sale of our family home of 55 years, a very emotional time for my mother. Ann Marie was knowledgeable about the market, professional, high energy but with patience, and sensitive to the situation. I would highly recommend Ann Marie to family, friends and others looking for a fabulous realtor.

Local knowledge:

Ann Marie helped us get a fantastic deal on an amazing house. We are very happy in our new home and it wouldn't have been possible without her help. She always responded quickly to our questions and emails and helped us through the home buying process.

Local knowledge:

Ann Marie helped me with the sale of my co-op. She was very knowledgeable and professional throughout the process. She priced the co-op accurately which brought in several offers and eventually resulted in a sale. I would highly recommend her to others in need of a skilled realtor.

Local knowledge:

Detailed and introspective which keeps the process in full swing. Market savvy and motivated to keep the sale positioned for closing. Highly recommend.

J. Murphy - July 12, 2017

Ann Marie is a thoroughly professional and highly capable realtor. She worked closely and patiently with us for a recent purchase in Crestwood that involved input from multiple family members. She is very knowledgeable about the local real estate market and provided valuable referrals, sound  advice and assistance through the entire process of finding and purchasing a home, right through to closing. Ann Marie is a pleasure to work with and we are pleased to recommend her without reservation.

Tom and Noelle McEnerney - October 4, 2013

Ann Marie is very responsive and knows her stuff. I purchased a home she represented in Bronxville over 2 years ago and has stayed in touch and continues to be responsive to questions and requests for referrals long after closing. She even researched permit and building issues for me (using her own  network) while I was deciding whether to make an offer on her property, which was above and beyond considering I was not technically her client. I recommend her without hesitation.

A. Hype - September 30, 2012

I had an excellent experience working with Ann Marie and would highly recommend her to all friends and family. Not only is her knowledge of the real estate market impeccable, but I also relied on her for personal advice which she tailored according to my specific situation.

D. Camb - January 11, 2015

Ann Marie is the best! She knows the market well and advised us correctly on our sale. She price the property correctly and got it sold in the projected time frame.

RF Schoetz - December 31, 2015

Ann Marie helped us with the sale of our mother's home after her passing. She was not only knowledgeable and professional throughout, but also was very sensitive to the emotional nature of the sale for me and my siblings -- this was our family home for 50+ years and was much more than a house.   She also provided great recommendations for service providers as we needed to get the house in shape before putting it on the market. We could not have had a better agent and I would recommend her enthusiastically and without any hesitation.

R. Petrilli - February 7, 2016

My experience with Ann Marie was outstanding. She was excellent in all facets of the sale of my home. Ann Marie gave me subtle suggestions on how to make my home attractive to perspective buyers. She was on target in regards to pricing accurately which brought in several offers and eventually  resulted in a sale. When negotiating and closing, she had my best interest at all times while remaining professional not only with me but also the buyers agent. I will be recommending Ann Marie to all my friends and family who are selling or buying real estate.

B. Sutton - February 11, 2016

Ann Marie is simply the best. She understands the market and takes time to understand what is important to you. We had a terrific experience as a first time home buyer because she took the time to speak to us and teach us about the important aspects of home ownership and the purchase process. I  will definitely recommend Ann Marie Sullivan to friends and family considering a new home purchase or a sale.
