What Clients Are Saying

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

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.
