5-star review
Andrea is the reason my fiancé and I closed on our new home! She took the time to understand exactly what we were looking for individually and as a couple. She has an incredible (or beyond incredible) understanding of the local market and was able to show us properties that perfectly matched our needs, even ones we hadn’t considered. There are many things that really set Andrea apart from other real estate agents, such as her negotiation skills, persistence, professionalism, and genuine care for us. She was a fierce advocate for my fiancé and I, and we are confident we got the best possible price for our home. Andrea was always available to answer our questions and guided us through every single step, making what could have been a stressful process feel easy and exciting. We are so grateful for her hard work and dedication. She goes way more than above and beyond. If you want a seamless and successful home-buying experience, you need to work with her ASAP. Neither I or my fiancé could be any more appreciative of her than we currently are! ❤️

“Andrea Costa proved to be extremely knowledgeable and informative about selling my house. Andrea went above and beyond her title of real estate agent to help get my house in tip top shape and show the beauty of it.  She was patient with me, answered my questions in a timely manner, and kept me up to date concerning the real estate market. Covid protocols were always precisely followed. I had complete trust that I was safe and respected in all our interactions. Andrea did not pressure me into making any decisions. My husband and I highly recommend using Andrea Costa to sell your home.”

Andrea was instrumental in finding us a property that suited us perfectly! We wanted to be close to town, and we needed to live on one level. We spoke about what we hoped for. Everything went so well. We’ve moved again and we would definitely call Andrea for our future real estate needs because she knows her market well and we always know she’ll put our interests first, listen to what we’re seeking and find us our perfect home.

Andrea has represented me in selling my house in Dix Hills & then again as a Buyer agent in the purchase of my next house. She also represented my sister as her Buyer Agent to buy a house in Huntington, NY. I am very happy with the selling price we got and timeframe, and working to find my next home. It was a smooth process, very successful. Highly recommend.
