Best broker I have dealt with

I cannot recommend Mary highly enough. When my property didn’t sell immediately, many agents might have lost interest or simply suggested dropping the price. Not Mary. She got creative with her marketing approach, explored new strategies, and brought fresh ideas to the table at every turn. Throughout the entire process, she gave 100% effort—her dedication and energy never wavered, even when the market was challenging. When we finally got to closing and things became a bit complicated, Mary handled everything with professionalism and persistence, making sure we got through it successfully. She’s the kind of professional who truly goes above and beyond for her clients, and I’m grateful to have had her expertise on my side. If you’re looking for an agent who will fight for you from day one until closing, Mary’s your person.

The Broker You Want in Your Corner – Highly Recommend!

As first-time home buyers, we knew we needed someone we could trust—someone who would guide us through the process with honesty, expertise, and genuine care. From the very beginning, Mary was exactly that person. She took the time to truly understand what we were looking for in a home and never once pressured us to settle for anything less just to make a sale. Mary's deep knowledge of homes and what to look for—both the good and the not-so-good—was incredibly helpful and gave us so much confidence in our decisions. Thanks to her dedication, patience, and professionalism, we found a home we absolutely love. We couldn’t be happier, and it’s all because of Mary. We highly recommend her to anyone looking for a trustworthy and knowledgeable broker.

Mary is experienced, clear, up front, and ALWAYS available

We started our home search with Mary a few months ago, and just closed last week. We couldn't have been happier with our experience. Mary has been buying and selling homes for a decade or two, and it's immediately obvious when working with her. On top of that, Mary is honest, clear, and incredibly available. She ALWAYS responds quickly to questions and is ALWAYS up for meeting. She helped us see tradeoffs that we weren't even yet considering, and she showed us the benefit of seeing homes outside of open houses, when you can take your time and examine a home in a way that's simply impossible during an open house. We hope to stay in touch with Mary, and will definitely be in touch again if we sell or buy in the future.

Real Estate Rockstar!

You will not find a better agent out there than Mary. Not only does she have incredible, real time insight about the market - but she knows all the players and is a hawk in making a deal happen. She stuck with us through several several houses and offers and got us over the finish line. She was a true professional to the very end - can't recommend her enough and look forward to continue working with her!

Exceptional, knowledgable and all around awesome professional

Mary was wonderful to work with and knows her stuff. Nothing was a problem and she made the process as smooth as could be. Any hiccups dealt with promptly and always easy to contact. I highly recommend Mary Kelly and property central. I have recommended her to family and friends and they were as pleased as I was. 5 stars is not enough. Simply terrific.
