Personable and prompt. Totally reliable. Very thorough and knowledgeable. Extremely helpful in all matters .

We had the pleasure of working with John for the third time over the last 9 years, both purchasing and selling of a home. John is very responsive. He listens to our needs, offers suggestions and recommendations. He is available by text, call or email. He also has a lot of patience with our multitude of questions and addressing our concerns. We would not hesitate to work with John in the future or recommend him to friends and family. It was a true pleasure and a comfortable experience. Thank you John!

John was fantastic during the entire process. He knows the market exceptionally well, and is the consummate professional. He is extremely organized and helped us through ever phase of the sale from the initial staging of our house, to the open houses, to reviewing our multiple offers. I can’t imagine another agent doing a more complete or better job than what John provided us.

John is a knowledgeable, professional realtor. He goes above and beyond to assist with a sale or purchase. I've worked with John on both sides, and wouldn't hesitate to recommend him. He doesn't get rattled when there is a challenge, and he always has a great attitude and a smile!

John brought a wealth of experience and knowledge to the table in assisting our family in buying a new home, while also selling the old home at the same time. John was on top of all the moving parts, organized and always promptly responsive to questions. Additionally, John was genuine and overall a great person to work with.

John, knows the market, was of great knowledge of the whole process of our sale. Always answered all questions and calls in a timely manner. We would highly recommend his services to others.

John Did an outstanding job in helping us to sell our home. His market research led to an asking price that recognized the value of our home and neighborhood. It also afforded us the opportunity to maximize our sales price. John helped us in many other ways as well. He did a great job fielding and responding top the buyers questions, while always protecting us as his clients. If you want a realtor that is thorough, personable, and with a great knowledge of the Cape Cod real estate market, John is your person!

I have known John for several years and have referred people to him who have had a wonderful experience. This time it was my turn. From the moment of discussion on whether to sell this property or my property I live in John was very professional offering market information. He worked with me with the pros and cons and when we decided to sell this property he was very helpful from the beginning. He had suggestions on staging the house and help direct me on how to get that accomplished. His real estate knowledge helped with negotiating the contract. Communicating every step of the way. Once the property was under contract he still assisted me with getting me help with cleaning and moving furnishings out. I will be using him again when I sell my property.

This is our third time working with John Mahan and each time is such a smooth and enjoyable process. He goes above and beyond to ensure all parts of the purchasing process are looked after and uses his expansive network to recommend attorneys, insurance agents, etc. There's never been a time when we haven't felt that John had our best interest in mind and truly cared about making sure we found the home that best suited our needs. If you're in the market to buy or sell a home, John is your guy!

What can’t we say about John? He was the best realtor we ever met, by far. John provided comprehensive information for our review, including voluminous information on the local market, pricing information, great insights into the buyer’s perspective (which proved accurate beyond belief), and other services above and beyond expectations. From our perspective, John is now a lifetime friend.

John was so knowledgeable . We needed guidance and education throughout the process and John was so patient. He really made the entire experience pretty painless and smooth. We can't praise John enough. We feel like we made a friend in the process. William Raveis is lucky to have such a hard working and dedicated team member. Thank you so much John!

Selling my property on Cape Cod required me to present at the Conservation Commission and the ZBA and John was present during all the proceedings. John was very helpful getting documents signed and delivered in a timely fashion checking various permits and Town Departments as I live off Cape. I would highly recommend John as a trusted professional as he was always reliable, dedicated and upbeat and he stayed shoulder to shoulder with me until the property closed.
