I couldn't have asked for a better agent to have by my side every step of the way. Katie is both professional and personable - simply one of the kindest people I've ever met. Throughout the whole process she was very honest, and so helpful helping me find the right property. Highly Recommend!

I had a fantastic experience working with Katie as my real estate agent. Her knowledge of the market and the buying process was truly impressive. What stood out the most was her ability to keep me calm throughout the entire journey. Her reassuring presence made a potentially stressful process much more manageable. I would highly recommend Katie to anyone looking for a knowledgeable and calming presence in their real estate journey.

Katie is the absolute BEST❤️ We couldn’t have done this without Katie helping us navigate this difficult market and time for buyers. Our location criteria was pretty specific and left us with slim pickings so when we found a house we knew we wanted to move forward with, it was Katie who made it happen! ⭐️⭐️⭐️⭐️⭐️

Katie helped us find our forever home! We were new to home buying and had heard horror stories from friends/family about terrible agents and bad experiences. We were so lucky to have found Katie! She is polite, available, friendly, honest, and knowledgable! She helped us every step of the way and made the process as smooth as possible. We highly recommend her!!

When I had to sell my parent's house a friend recommended Katie O'Hara and I am so glad she did. Katie and her associate Kristin came to meet us, viewed the house, discussed the local market in the area, and answered all of the questions we had about the process, steps and typical timelines, all in a calm, relaxed, no pressure vibe. It was easy to decide to go with them. Throughout the process Katie and Kristin worked as a team with great communication. They were very responsive, always answering any question and concern I had, and offered advice and practical solutions when needed too. I really felt like I had 2 good friends walking me through this process. Our house sold quickly with multiple offers, and the buyers loved Katie O'Hara too. Katie is professional, kind, knowledgeable, caring, empathetic and really passionate about helping people find and sell homes. I definitely recommend her and feel so grateful to have had her help in this process.

Katie did an outstanding job selling our home. She is extremely easy to work with and very attentive to any questions we had. Her attention to detail is superb! Katie brought a professional photographer in to photograph our home- those pictures came out beautiful. Her knowledge of the market and calm and reassuring presence made selling our home so easy. We were in great hands! I HIGHLY recommend Katie to sell or help you buy your home!

Katie was excellent throughout our entire house buying process. She was always available for any questions we had as well as viewings and was very helpful communicating with any other agents and sellers. She is extremely knowledgeable of the market and towns, and knew what questions to ask at all points. I would recommend her to anyone and everyone going forward and can confidently say we would not have been anywhere near as successful at finding a house without her.

Katie was recommended by a friend with the most glowing review about how quickly and efficiently she sold their property, so I gave her a call. Let me tell you - working with Katie is a dream, especially if you appreciate someone direct, up front, and honest. She will tell you the truth, even if it’s something you don’t want to hear. She is always working on behalf of her clients' best interests and tirelessly for each and every one. You will feel like you are her only client every time you speak to her, as she gives you her undivided attention. She offers excellent advice that I highly recommend you take to heart. It could’ve been luck of timing, it could’ve been the luck of the market… However, I think it was the tenacious work ethic and the luck of finding Katie that got our condo sold in about three months for over asking. She is, to quote Tina Turner "Simply the Best"!!!!

I rarely leave reviews but I absolutely HAVE TO recommend Katie. My landlord sold the house I was living in for 5+ years and moving wasn't on my already hectic list of things to do. I contacted her and told her what I needed ASAP. She found me a really great space with potential... two bedrooms for the price I was expecting to pay for just 1... 15 min to work... and a DISHWASHER as a bonus. She was kind and patient and even drove out of her way during rush hour to meet with me to make sure she could meet all of my needs and personally show me the spaces she found for me. She helped me fast, too. TWO weeks after getting the call I had to move, I am in a new place that feels like an unexpected upgrade. Thank you so much!

I don’t even know where to start with this review because words are not enough to say thank you to Katie for all her and her team did to sell mom’s house. They are the most professional and caring realtors I have ever met. They came in prepared with comps in the area and the knowledge was like I said I can’t put it in words. My mom would have been so happy that we chose you to sell her wonderful home with such caring and love. We thank you from the bottom of our hearts 🥰

We had been on the hunt for a house in Suffolk County for TWO years due to this crazy market. We had a hard time finding an agent due to being very picky and first time home owners, we needed someone who understood our needs but also had tremendous patience. Katie helped us find our dream home and helped us with every step along the way. She made the whole process easier and stress free in what normally is the most stressful decision of your life. We could not have asked for a better agent!!

Katie is everything you want and need in a Real Estate agent. She guided us through our house hunt, she always had insights on the neighborhoods we were exploring and always asked the right questions, even when I would forget. She was patient as we navigated and explored different neighborhoods and options until we settled on the neighborhood and home we wanted. In an extremely difficult and competitive market, she shined with the negotiation. She made sure the deal came our way and made sure the seller and sellers agents felt comfortable with us as buyers, since they had a deal fall through already. She was the lead of a surprisingly seamless and quick transaction. I highly recommend her for all your buying needs.

We live on the water and were hearing about houses not closing because they did not have a Sandy permit. We asked Kathrine to help. She found out that our house needed a permit. She guided us through the process and we received our permit. Katharine and her team came with a marketing plan. Had our home professionally photographed and put our house on the market. 8 days later we were in contract with a selling price over asking. She even sold our boat. All in all a stress free transaction. We highly recommend Katharine and the matchmaker team from signature premier properties.

Let me start by say that Katharine was on top of her game when it came to selling my home in Wantagh. I was so impressed on her kindness, caring, knowledge and how professional she was. If anyone is even thinking of sell or buying a home please contact Katharine for any questions you may have. Thank you again helping us with our sale.
