Excellence in Selling

I've worked with Libby on the sale on 4 of my properties and am so grateful to have her as my realtor. She was wonderful, went above and beyond to help us and make the process as smooth as possible and as profitable for us as possible. I highly recommend her to anyone looking for a realtor and do  hope have the opportunity to work with her in the future.

Excellence in Selling

"Professional but friendly, Libby guided us through the selling process and managed our expectations and thought outside of the box. Where we had others counsel that we needed to do all sorts of upgrades in order to 'compete' in the market, Libby instead knew exactly how to market the house to show-off its features. Thorough and responsive, more than once, she had to also calm our nerves in a process that was already fraught by nerves brought about by CoVID as well as a country relocation. We cannot recommend her enough. By the way, we initially bought through Libby after she was introduced to us and six years later, after reviewing other candidates, she was the only person we felt was the right fit to sell our house."

Excellence in Buying

Picture having a resourceful, insightful, encouraging best friend as your real estate agent and you have Libby Mattson. Even in hindsight, our family breathes with such relief in our fortune to have Libby at the helm of our first home buying adventure. After quite quickly developing an uncannily  shared vision for what we wanted, Libby asserted the perfect balance of persistence and patience, while also providing just enough wisdom and guidance throughout to allow us to draw our own good conclusions as we saw several homes before finding our literal dream home. Libby is strong on communication and remarkable accessibility (we still owe her for all the high-stakes support she provided while on VACATION!). But most importantly, you can feel Libby pulling for you with each home toured. Libby also manages a great collaboration with fellow agent Barb, as a tandem dead set on creating a comfortable relationship with their clients en route to fulfilling their real estate goals. This is a review, but also a massive note of thanks to Libby!

We could not have imagined a more effortless and, frankly, enjoyable house-hunting experience. When we needed a recommendation for an agent in Fairfield County, Libby was the first name we heard and we were so lucky to have had her by our side. She was more than happy to take us to every single  house that caught our eye until we found the one. And when we did, Libby was there every step of the way to make sure it all went smoothly. We found our dream home thanks to Libby - and we had fun doing it thanks to Libby! She is absolutely a pleasure to worth with and will be our recommendation for anyone looking in the area.

Excellence in Buying

There aren’t enough words to describe how incredible Libby was during a very important chapter in our lives- buying our first home. Libby was extremely thorough, responsive, and was ready, at a moments notice, to answer any questions we had. She made the home buying process extremely easy for us  and explained the next steps, every step of the way. She eased our concerns and promptly followed up on any questions we have for the sellers. I would 100 times over recommend Libby to anyone looking to purchase or sell their home. She will treat it as if it’s her own. You’ll be in good hands!

Libby is amazing!! She was recommended to us by my good friend. We started our journey with her in December 2016 to look for our first home. From the beginning she was incredibly helpful and knowledgeable. She listened to us and knew exactly what we were looking for in a home. It was so easy and  wonderful to work with Libby. It is obvious she loves what she does and we were so lucky to have her as our realtor. We looked at many many many homes and finally found the one for us in New Canaan and closed in October 2017. Libby helped us throughout the entire process and even still helps us if we have questions. As much as I am happy to be done looking I do miss hanging out with her! We are so happy to be in our beautiful home and are so grateful for Libby! She really is the best! Thank you again so much!

Libby is absolutely the best realtor I have worked with. She was well researched, well prepared, highly organized and very practical. She was also a solid communicator, even when delivering a dose of needed reality to me as a seller. I would recommend Libby to anyone.

"Libby helped us find a wonderful house that met our unique set of qualifications. It took a good six months of looking, and looking, and looking. And through the process, refining our target, having offers ignored or declined, and finally finding the right match, Through it all Libby was positive, patient and enormously helpful. And wonderfully enjoyable to work with."

5 Star Buyer Researcher

I am more than happy to recommend Libby as a superior Real Estate Agent for anyone throughout the Fairfield County markets. Libby is an extremely passionate and proactive professional. She does not believe in waiting for opportunity to come to her and her personable demeanor screams ambition & that "go getter" attitude. My first impression when meeting her was nothing less than FIVE-STAR!!! Even during the lengthy home inspection process she is completely engaged, organized and has her own pure sense of high level technical knowledge.

I cannot recommend Libby more highly. Libby helped us find and close on a house in North Stamford. She has a unique combination of market knowledge, valuable intuition and with a conscientious nature, always willing to go the extra mile.

Libby was such a godsend when we were trying to find the perfect house for our family! Personable, thorough and not pushy at all, Libby really listened to what we were looking for in a home and was super helpful from the very get-go. In fact, we had to contact her after the sale for advice on other matters and she did not let us down!

My husband and I have had a lot of experience working with realtors over the years. Libby Mattson, was by far, the best agent we have ever dealt with. Her work-ethic far surpassed our expectations and extended beyond our property closing. She kept us informed up to the minute with regards to inspections and negotiations. Her honesty was a breath of fresh air and greatly appreciated. In addition, she really went out of her way to resolve any issues that arose during the home buying process. Libby is the most helpful and organized person in the business. She is a total professional, yet extremely personable! Even months after we purchased our home, she continues to check-up on us to make sure all is well. Our experience with Libby was excellent and when the time comes to buy/sell another home, she will our only agent of choice!
