Rave reviews for John Mahan. We recently sold a home that had been in the family our entire lives. John was our “therapist” as well as our realtor and handled all aspects of the sale and prep of the house with sensitivity, experience and fabulous recommendations of people to help with all the situations that needed to be addressed. I highly recommend John, it was a very simple and nondramatic event. I don’t know how he managed it but we are also thrilled with the family that bought the house.

He was there from start to finish through out the whole process answering any and every questions that came up.

John went above and beyond for us every step of the way. His communication was outstanding, attention to detail incredible, and he always made time for our questions and concerns. His knowledge and contacts in the area were such a benefit as he answered so many questions not connected to the sale. An absolute pleasure to work with and I have no hesitation recommending him in the future

We've worked with our fair share of realtors in the past. John has helped us with more than one purchase, and each time we were successful because of the guidance and advice we received from him. John knows the Cape well, and if we purchase another property in the future it will certainly happen again with John's help.

John came highly recommended by a close friend, and he exceeded every expectation in helping us find our home in Harwich. His deep knowledge of the Harwich and Chatham markets, combined with his warm, engaging style, made the entire process feel seamless—even in a highly competitive environment. We navigated multiple offers before landing our Cape home, and John’s guidance, strategy, and steady expertise were invaluable at every step. He took the time to truly understand our priorities and consistently presented thoughtful, well‑matched options. We couldn’t be happier with the experience and would enthusiastically recommend John to anyone searching for a home on the Cape. He’s outstanding.

John went above and beyond in all aspects of the selling proces! John had the entire plan for the staging, pictures, listing in place so that when we were ready, it went smoothly and without a hitch! We had offers 3 days after the house was listed! John's communication, professionalism, patience and support is exceptional, really a 10 star rating.

John was extremely patient in adapting to our needs which varied from an original home search to ultimately a land sale. We worked well together researching answers to technical questions as well as finding sound legal advice. John was spot on with his market analysis and he provided valuable advice on determining sales price. I highly recommend John to be your real estate agent.

John Mahan went above and beyond to guide and support us in the purchase of our new home. John was actually on vacation when the home we decided on became available and he did not miss a beat getting us any and all information needed, walking us through the offer process and offering advise as needed. John was professional through the entire process and made it seamless! We are now working with John to sell our previous house and he is providing the same guidance and support!

John Mahan is an exceptional broker who recently assisted us in finding our dream house in Harwich Port, MA. We had very specific search criteria as we looked for the better part of the last five years for a suitable match. Throughout that time, John was incredibly patient and professional as we considered many properties and bid aggressively on a few homes. The property we just bought through John had been in the same family for almost 100 hundred years and there were a myriad of physical property and regulatory issues that needed to be investigated and resolved. John was incredibly diligent and thorough in his efforts to address each item in a comprehensive and timely fashion. His thoughtful interaction and strategic coordination of third-party consultants, town officials and attorneys was instrumental in our ability to close without issue or delay. Stylistically, John is very personable and good natured ....we were absolutely delighted to work with him. John & Pamela

John exceeded expectations for service and attention to detail. He stayed in constant contact throughout the process. He is very reliable, always able to reach him with questions or concerns. He has an intimate knowledge of the local market. His business relationships and contacts helped us complete projects for the sale. Can't say enough about his professionalism. Working with John greatly reduced our stress and he was a pleasure to work with.

It was a pleasure working with John. He really understood what I was looking for and he found it!!!! John was thorough and a pleasure to work with. I would highly recommend him to anyone looking for a home on Cape Cod.

John was very hands on and professional. Always answered my questions immediately.
