About Martha Knapp

Cape Cod has always been a part of my life. Growing up in a suburb of Boston, I often traveled here as a young child to visit relatives and enjoyed camping each summer with my family in various areas across the Cape. Our days were spent at the beach or exploring, and our nights were filled with campfires and stories. I have fond memories of collecting sharks teeth at Head of the Meadow Beach in Truro, climbing the sand dunes in Provincetown, experiencing the local theater, and visiting all the quaint artisan shops along Route 6A.


In 1986 I opened a business in West Dennis and was fortunate to have the opportunity to move to the Cape year-round.  In 1994 my husband and I moved to Harwich with our two children, and we’ve called it home ever since.


I believe the Cape is more than a's a way of life.  Each of the many villages throughout the coastal sprawl offers unique character and charm.  Whether you are looking to relocate your primary residence, or purchase a second home, when the beauty of the area touches your soul, you know you have found your home...

Why They Choose Me

Martha made the selling process incredibly easy from start to finish and was a pleasure to work with. She knew the market, how to price our house competitively and recognized the value of certain details we had done to set our house apart. She did professional photographs, complete with overhead drone shots, to showcase our house online. We had three offers within two days! Once she had secured the best offer, Martha continued to guide us to closing, always keeping us informed of deadlines and being immediately responsive to any issues or questions we had. She negotiated skillfully with the buyers and their agent in all aspects of the deal. We highly recommend Martha!

Martha was WONDERFUL!!! She knew the area and helped steer us to the PERFECT house. She was very knowledgeable about the process which was extremely helpful since we were first time home buyers. I would use her again and I definitely would recommend her to anyone that is looking to buy or sell a house.

~Margaret & Steve S.


Martha seemed to know everything about everything regarding the process of finding and purchasing a home on the Cape. She was wonderfully patient when showing us countless houses. She responded quickly and thoroughly whenever we had a question or concern. She was organized and professional. Working with Martha was a great experience.

Martha is an amazing Real Estate Agent! She handled everything quickly and professionally, she does a lot of behind the scenes work to get the job done i.e. speaking to the mortgage lender, my attorney, and the other agent.  Martha kept me informed of what was going on but she was able to handle most of the problems without involving me.  She always works in the best interest of her client.  I trusted Martha and her judgment immediately – she has great instincts; she’s friendly, warm and funny!  I was so happy that I met – not only did I get THE BEST agent on the Cape but I also met a new friend.  I can’t say enough nice and true things about Martha.  Every time after I spoke or met Martha in person, the first words out of my mouth were “I just love that Martha!”.  Martha is truly amazing!

We recently purchased a home on the Cape with the outstanding help and professionalism from Martha Knapp. From the beginning, she listened to what we were looking for in a home and made the process so easy and enjoyable. Her amazing attention to detail and professional judgment with all that went into this purchase was so appreciated. She went to great lengths to show us the surrounding area, including medical facilities, stores, restaurants and even shortcuts when the summer traffic returns. My husband and I can't say enough about the positive experience we recently had with Martha. You will be a very lucky to connect with Martha Knapp!

~Gail & Steve H.

My husband and I were extremely pleased with our experience with Martha Knapp. She was friendly and professional, honest and informative, and ready to help us throughout our process. We felt that she worked for us, gathering information between meetings and really listening to our feedback when we were together. Once we found the right property, she was responsive and supportive throughout the negotiation process.... She was attentive right through the closing, and remained in touch afterwards to ensure that we were satisfied with the process. We are thrilled with our purchase, and have already recommended Martha to friends. She was wonderful to work with, and a true expert in the world of Harwich real estate.

I want to thank you for all your support, kindness, advocacy and real estate expertise with the listing, marketing and sale of my Cape Cod home. I was so excited to be moving to Santa Fe, NM, after so many years on the Cape. The process of listing and selling brought up feelings of vulnerability, trust, and honesty. All along the way, you projected an honest, truthful and supportive approach. I feel as women, we empowered each other to create the sale and work together in harmony to achieve a goal. And I might add in a very short period of time! I am very grateful for your presence in my life, your future clients are very fortunate to have you as their guide on the real estate journey.

Last winter our family endured a health and safety crisis involving my elderly parents who lived in their beloved home on the Cape. I had to sell my parent’s house quickly in a very poor market. The situation was made even more difficult by the fact that I live hundreds of miles away in Central Maine. Martha offered calm, detailed guidance every step of the way through many complex obstacles. She remained optimistic and kept us focused on moving forward with one seemingly impossible task after another, often helping in ways that far exceeded our expectations.

Martha Knapp’s hard work, perseverance and optimism produced a great deal of interest in the house and it was sold much more quickly than some comparable homes in Eastham. I can truly say that I would offer my very highest professional and personal endorsement of Martha Knapp.

~Chris D.

Martha takes the time to get to know her client and their needs. She was extremely helpful in offering suggestions to us and assisted in going to the property when we were not available to do so to let people in who were doing repairs. She outlined next steps and we felt completely in the loop at all times. She contacted us and let us know what was going on at all times. She did not push us into anything, but provided her expertise and let us make decisions. Very professional and extremely dedicated to her clients.
