Dawn Costello Real Estate Agent

We had a wonderful experience working with Dawn! From the very beginning, she was incredibly helpful, knowledgeable, and generous with her time and advice. She took the time to truly understand our needs, answered all of our questions with patience, and guided us through every step of the process with professionalism and care. What really stood out was how genuinely kind and supportive she is — you can tell that she truly cares about her clients and wants the best possible outcome for them. Her insights and recommendations were thoughtful, honest, and extremely valuable. If you are looking for a real estate professional who is not only highly competent but also warm, responsive, and trustworthy, I cannot recommend Dawn highly enough.

Dawn is fantastic!!! I highly recommend working with Dawn for any of your housing needs! She was very considerate and mindful of all my specific requests in a rental unit. She worked efficiently and was always a joy to work with while going through the process of finding apartments to apply for. Thank you for helping my process be a success!! If I have a next time in the Long Island Area, I certainly will be calling Dawn!!!! Thank you, Dawn!

Dawn went above and beyond throughout the entire process of my CO-OP purchase. Her professionalism, attention to detail, and constant support made everything smooth and stress-free. Dawn is always available and ready to help, she truly care about her clients. I highly recommend Dawn to anyone looking for a dedicated and reliable real estate agent.

Dawn Costello is an absolute credit to her profession, and I would highly recommend her to anyone seeking her expertise. I am an attorney, and have dealt with many brokers over my 30+ years of experience, both on LI and throughout NYC. I was quite fortunate to be introduced to Dawn through a client. We recently had a sale in Sea Cliff for a home belonging to a recently deceased client. It proved to be challenging on many fronts, and involved many parties with different interests and goals. Dawn was able to contend with the many disparate issues that arose, was easy to contact and eager to assist without fail. She always went the extra distance to get us to sale, even when the challenges went beyond her professional expertise. Her recommendations brought us to a quicker sale and closing,

Dawn was an absolute pleasure to work with. Her professionalism and expertise helped us understand the current rental landscape and help set the right rental rate for our property. She was in constant contact with us and showed the apartment to numerous prospects. In a relatively short period of time a great match was made. When we’re ready to rent, sell, or buy in future we’ll be calling Dawn. Thank you!
