I can give the highest of all recommendations for Margaret O'Sullivan! Margaret exhibited tremendous knowledge, effort, and caring in all ways throughout our entire home sale experience.

"I just bought my very first home, and I am so glad that I found Margaret as my agent. Margaret’s philosophy is that the most important thing is that her client is happy. As a first time home buyer, she explained every single detail to me, made sure we stayed on track, fought for me every step of the way, and encouraged me when the process felt overwhelming. I was 100% confident that Margaret was in my corner every step of the way. She is the best agent I’ve ever worked with during my very long search for a first home. I would hire her again in a heartbeat, and you should too!"

My family and I were very impressed and delighted with the job Margaret O'Sullivan did for us selling our house.  From the initial meeting to the final closing, Margaret was extremely kind and cared about all our concerns and questions about selling our home after being there for 26 years.  She has  great knowledge about the market, did her homework on pricing, understands the entire process, has a great team behind her and works hard at every step. Margaret has an amazing stager and crew to help with the whole house, even moving furniture around for you.  Our attorney even commented that she was exceptional in her service and was a delight to work with. At times on our sale, we ran into a couple of speed bumps.  Margaret moved quickly to solve those issues so that we could close on time.  Most of all, from my perspective, she was "present" for everything.  Every showing,  Every contractor.  Every step.  She was there beginning to end to make sure it was done right. To say, it meant a lot to our family, is an understatement, Margaret started out as our realtor but we ended up being friends. We highly recommend Margaret O'Sullivan to anyone looking to sell or buy a home

Margaret O'Sullivan was by far the best agent we have ever had. She brought her A game from day one and completed the sale with some major roadblocks without hesitation. Margaret and her team were amazing and can not recommend anyone better.

Margaret helped us find our second house and sell our first. We were very particular about what we were looking for and were not easily satisfied. Margaret never wavered in her commitment to us and worked patiently and determinedly to find us a house that met our requirements. And she went above  and beyond in helping us prepare our first home for sale. We couldn’t have done it without her knowledge of the local market, careful guidance, and connections to area tradespeople. We always felt that she was looking out for our best interests. Our previous home sold the first week on the market and we are exceedingly happy in our new home. We wholeheartedly recommend Margaret to anyone looking to buy or sell a home .

It is important to like, know and trust the people you work with. I knew right away Margaret was the right person to help us sell our home. I had observed her a year earlier working with a client looking at a house for sale in our neighborhood. She was friendly, easy to talk to and openly discussing the market, the house and the neighborhood. (I value open and direct communications.) Because I saw her in action, she was the first person I called to come to talk with us.

Phil - Reading, MA

Margaret is simply amazing! She takes “white glove service” to the next level. She truly went above and beyond, time and again. We would highly recommend Margaret to partner with when buying or selling a home. She is honest, knowledgeable, professional and especially “tuned in to the market”! You will be happy you selected Margaret O’Sullivan to represent you and your interests with such an important, life impacting transaction…….although she treats it much more than just a transaction!

Hire Margaret O’Sullivan. Just do it and I promise you it will be the best decision you make in the complicated process of buying and/or selling your home. We met Margaret 5 years ago, when she sold us our very first house. She worked tirelessly on our behalf and gently encouraged us to look in  towns that would appreciate when we needed to sell (perhaps foreshadowing we would outgrow that house 5 years and 2 kids later). This year, we hired Margaret again. She promised us she would go to bat for us at every turn and WOW, did she. The week we were set to list, the COVID19 pandemic hit and the world turned upside down. We paused on listing amidst the uncertainty and Margaret was supportive every step of the way. We stayed in touch and a few months later, we decided to list. She sold our house in one weekend, with multiple offers, at well over our asking price. On the buy side, because of the pandemic and the record low interest rates, the market was dizzying. We were starting to lose hope but Margaret never wavered that she would find us something great. Today, I write this review from my beautiful new home that never would have been possible without her. The outcome could not have been better. Margaret believes in ethics and hard work and it shows in everything she does; from her unending hustle on behalf of her clients to the high quality people she partners with (through her we found a fantastic interior designer, a great painter, a top mortgage lender, a moving company, our lawyer, the list goes on). If you want someone you can truly trust to handle every bit of this process, Margaret O’Sullivan is unmatched in the industry.

Margaret was recommended by a family friend and we were not disappointed. She patiently and skillfully guided us through a very stressful major life event. - the sale of our family home that we had lived in for almost 30 years. Her advice on how to ready our home for sale was based on her solid  experience with what works in the house market place. We could not have been happier with Margaret and her team. We would highly recommend them to anybody buying or selling their home

We had a wonderful experience with Margaret. This was our first home purchase, and her guidance was invaluable. We worked with Margaret for several months; she was always available and more than willing to provide insights into the market and schedule home tours. Our relationship with Margaret  continued even after the purchase of our home. She shared her extensive local knowledge, lenders, attorneys and quality recommendations for our home improvement/redesign needs. Margaret was truly invested in our endeavor to find the perfect home and was a resource throughout the entire home buying process. We would recommend her to anyone!

Margaret provided such an easy, stress-free experience. She was always responsive and provided knowledgeable information as needed. Any time I needed her day or night, she was available. She provided reassurance and knew we would find something perfect. I will definitely be using her for the future.

Anissa & James - Wilmington, MA
Our experience with Margaret was awesome. If you are looking for a real estate agent, and you have high expectations - you are in the right place. She took so much pressure off the process of selling our home! We needed the experience to be as stress-free as possible because of other issues we were dealing with at the time. She delivered.
She was our advocate at every turn. At our request, she even took care of having improvements made before the house went on the market. We had a small budget but Margaret made it work. Her recommendations for preparing the house for viewing were right on target. The house sold quickly, and over asking price.
