Karen was our Buyer's agent. She was amazing to work with. Personable, professional, knowledgeable, and available. She always got back to us right away. She was flexible with regard to when we needed to get to a showing as we were coming from north of Boston to the south shore. Karen knows the market, and guided us to the home that was the one in a crazy market.
Karen was fantastic to work with. My husband and I each had unique sets of requirements in a house and Karen found us a property that we both LOVE! She attended all open houses, answered all our questions and guided us through the process. In this stressful market she was a calming force. We have already recommended her to family and friends
Karen was amazing during the search for our new home. Her knowledge of the area helped us to pick the right house in the right neighborhood. Karen attended all open houses with us and followed up with any questions we had. Karen's patience kept us calm and cool in a very stressful market. Karen continues to check in with us and help us learn the area. We are very happy with our new home and consider Karen our first new friend in town!
Karen helped our family to sell our Dad's house after he passed away. In a unique market and under emotional life circumstances, she confidently led the way. From making recommendations on home updates, photographing the property, posting and listing the property, managing open houses, and negotiating and coordinating the process, she is a master at her craft. She is also a good, honest, straight shooter of a person. She was trustworthy and reliable throughout the entire process. I highly recommend her without reservation!
We had an amazing experience working with Karen. She guided us through all the steps of finding and buying our first home (while we were living halfway across the country) and ultimately helped us land a perfect home. I cant recommend Karen highly enough!
We loved working with Karen. She was quite possibly one of the best real estate agents we have ever worked with. She was thoughtful, kind, paid attention to us, and honest. We are so happy with our new home and our time working with Karen. We were actually sad to no longer be working with her.
Karen did a fantastic job for us! She was thoughtful, knowledgeable, responsive and detail oriented. She has great energy and was a pleasure to work with. Would not hesitate to use her and her expertise again!
Karen is amazing!! She is down to earth and does not pressure you into buying a home you dont need or want. She helped my fiancA(C)e and I buy 2 homes and sell 2 homes. Both homes she sold for us we got the highest sale price in our neighborhood. We love you Karen!
I highly recommend Karen. She was an incredible ally in helping us navigate an extremely competitive 2021 housing market, and ultimately helped us secure our beautiful new home. Karen's unique knowledge and expertise of south shore listings was instrumental in the crafting of our offer, which prevailed over about 20 others. She was by our side every step of the way- always available at a moment's notice to answer questions or provide a sense of calm and assurance during stressful moments. I truly feel she went above and beyond for us- and while I hope we never have to move again- she will be our first call if we do!
The day my house hit the market Karen had 40 showings and 8 offers within 24 hours. Every step of the way Karen guided me. She impressed me with her professionalism, work ethic and overall knowledge of the the South Shore market.She worked hard and got the job done. I enjoyed working with Karen and highly recommend her.
We were so fortunate to have found Karen Mullen to work with as our Realtor. She was remarkably helpful during the entire process, and helped us find the right home, in the right neighborhood for the right price. She worked well beyond what one could expect. She was always available to answer questions, do some research, and get us right in to see a home as soon as it hit the market. And in a market that homes were scarce, Karen went that extra mile for us to find us just what we wanted.
Karen was a joy and easy to work with right from the start. She understood our needs, was patient with our decision making, and always there for us right away when we needed her. Karen also has an upbeat attitude and nurturing mentality that is so appreciated during a somewhat stressful time. She is amazing at what she does - she found us the perfect house and sold ours quickly. Highly recommend Karen!
Karen helped my family find a home as we were relocating from connecticut to Massachusetts. I really can't say enough nice things about her and her work ethic, patience and charm. We had a very tight schedule to find a home in a very difficult market and she did all of the right things to make that task as easy and as pain free as possible. Spending full days on the weekend driving all across to south shore to look at sometimes close to 10 houses a day and never once making us feel as though we were inconveniencing her. Karen's contacts in the real estate world were second to none also and were extremely helpful in the other difficult parts of finding a home. Overall I don't think that you could find a better person to list your home with or to help you find your forever home. Karen is just as good as it gets.
I was looking for my dream beach house and Karen made my dream come true! She is an amazing realtor that offers the entire package of house buying. She listened to what I was looking for ~ she found the perfect home for me ~ she provided on going support through the entire house buying process and referred me to wonderful resources to help with all the pieces. She went above and beyond in answering all of my questions. She has a great network of resources and every time I asked if she knew someone (attorney, contractor, electrician, etc.) she always had a name for me! I came from out of state to purchase a home and from day one, she was there to help me with the entire process. I would highly recommend Karen Mullen to anyone that is thinking about buying or selling property!!!!
Karen helped get us buy a house in our dream neighborhood because she had knowledge of a home that was coming soon. We were one day ahead of other buyers and it really helped us get a leg up. She also got our house photographed and listed 3 days later and under agreement on day 1!! She is lovely to work with, helpful in talking us through issues that arose, and we highly recommend!
When we made the decision to sell our house, we assumed we would have a difficult process ahead as the home selling process can be pretty involved. What we found however, by partnering with Karen Mullen as our realtor, was that she was able to successfully and EASILY navigate this process on our behalf. Karen's tremendous experience allowed her to not only ensure many headaches were taken off of our plate but she anticipated potential challenges and diffused them before ever reaching us. She has a tremendous network of professional contacts that helped us with tasks in getting our home ready. Most importantly Karen's positive attitude, flexibility and commitment to client satisfaction all played a role in her selling our home quickly. We would HIGHLY recommend Karen to any prospective sellers(or buyers.)- Sincerely Lori and Sean Roche
Karen helped me with a rental and a purchase. Over the years, I have worked with several great Agents, but no one compares to Karen. What makes Karen stand out is her personality and her effectiveness to help you, the customer decide what is best for you. Karen is extremely knowledgeable about the community (we searched for houses over a 30 mile radius) and Karen knew everything from schools, restaurants, community highlights, and future potential of upcoming areas. If you want the best, call Karen.
Karen is an amazing agent, a professional in every sense. She made the process of selling my out-dated antique farm house virtually stress-free. I would highly recommend Karen to anyone looking to sell or buy a home. My experience was much more tolerable, from beginning and listing, through to closing and right on to finding my next home. A big thanks to Karen!
Karen was amazing to work with every step of the way. She helped us understand the market, evaluate options, get us into properties before they were officially listed and ultimately in negotiating to purchase our dream home. Throughout the entire process, she was incredibly responsive and patient with all parties involved. We were lucky to have Karen as our realtor and HIGHLY recommend her!!!
Karen is a "no pressure" realtor, a rare commodity. Always pleasant, always cheery and willing to help (she even helped me disassemble a bed frame) Always on time and always familiar with the details concerning the sale of my property. Karen is a true professional. It was fun being in her company. She's perfect!!!
Karen was a consummate professional who did the little things throughout the process that made all of the difference. When we were originally working with Karen, we were looking at buying a home. When we decided to pivot and build a new construction, Karen guided us through the entire process. She held our hand through 10 months of our home being built and made sure we were handling everything necessary along the way. She found us a mortgage lender that got us an incredible rate, and an attorney who was easy to work with and had reasonable prices. Karen took the time to get to know us and what we valued. She was incredibly knowledgeable, personable, professional, and fast. She ironed out any hiccup that popped up, was patient with our hundreds of questions, and was a big part of our dream home being built. I recommend Karen to anyone looking to sell or purchase real estate and I will use her with any of my real estate needs in the future. On a personal level, I like Karen. She's honest, down to earth, she's a part of the local community herself, and is simply trying to help people find the type of home they're looking for.
After a year of hard searching, we are finally first-time homeowners! We would never have been able to buy the house of our dreams without Karen! She was always only a phone call, email or text message away when we had even the smallest of questions. She helped ease the pain of losing the first house we looked at after a bidding war through reassuring us that it wasn't meant to be and, when it came time to bid on our house, her quick reaction time and negotiating skills sealed the deal for us! We beat three other offers.Karen is a true South Shore local with an extensive network. She has brokers, lawyers, inspectors and more all on speed dial! It was great to work with people she knows and trusts throughout the whole home-buying process.We love and trust Karen and WILL use her again when it's time to move on from our home sweet home, but for now, we just recommend her to everyone we know!Thanks for the stellar experience, Karen!Kevin and Heather
Karen Mullen is a true professional, in addition to being a warm and wonderful person, exuding authenticity, honesty, and integrity. She knows her business and offered just the information we needed at the moment we needed it on our journey to a new home. She is unflappable and quietly persistent, and injected a sense of calm into all our interactions aEUR" especially when we didnt feel that way! Karen is incredibly responsive, even as she enjoys her delightful family and lots of community service. She makes you feel good about the client/realtor relationship every day, especially important as the business of home selling and buying becomes more and more complex. We recommend Karen with enthusiasm and gratitude.
Karen is knowledgeable, friendly, and always professional. She goes above and beyond what is required to represent her clients in the Real Estate transaction. I would highly recommend Karen to anyone who is looking to sell or buy Real Estate.
Karen was fantastic to work with. She is very knowledgeable of the area, give us great advice and was patient and committed to help us find what we were looking for. Karen understands the market and took the time to get to know us. She was positive, honest and a pleasure to work with. I would recommend her for anyone selling or buying a new home.
Karen has a special combination of professionalism, warmth and compassion. We had a lot of moving parts during our home sale. Her expertise and complete understanding of the market and process allowed me to focus on other matters. She also found me the perfect home rental for an interim period. I will call Karen again for a future purchase. I highly recommend Karen!
My husband and I were referred to Karen by some very close friends who also worked with her for their home purchase. We were SO happy with the entire experience. Karen always had our best interest in mind. She is super responsive and we always felt like we were the most important clients to her because of how fast she responded to our questions and resolved matters. Even though we are now happily in our dream home, Karen is someone who we consider a friend and will always be our 'go to' real estate professional. If you are looking to buy or sell real estate, I highly recommend Karen!
Karen was a pleasure to work with both on the buying and selling side. She always went above and beyond to make sure that we were on top of anything that needed to get taken care of, and her advice helped us out negotiate another buyer and then sell our house in 1 weekend. We couldn't be happier and absolutely recommend working with Karen.
I was thrilled to work with Karen Mullen and Tricia Duffy of Caldwell Banker, Scituate when I had to sell my home. They were friendly, efficient, and highly responsive to every call, text and email. They gave great advice and provided excellent referrals when I needed help getting my house list-ready on a tight budget. They have built a solid professional network on the South Shore with an expertise in the Scituate, MA real estate market. The pricing and timing strategy they recommended to me was spot on, and as a result - I received 3 competing offers the day of my first open house, and went under agreement the next day with a cash offer +$17k over my asking price. Botton line - Karen and Tricia work extremely hard for their clients and get results. They are honest, hard working women and simply good people. You can't go wrong with Karen and Tricia!
Karen is a true professional who really cares about her clients. She explained the whole house buying process in a clear fashion. She was always available for any questions as well.
We have known Karen for years and she made both the buying of a new house and selling of our current house such an easy process.She has tremendous knowledge of the South Shore real estate market and understands every step of what needs to be done to either buy or sell a house.Will highly recommend Karen to anyone looking to either buy or sell on the South Shore.
Karen was amazing. She knows the Scituate and surrounding area incredible well, negotiated expertly on our behalf, and helped us prep all the things we needed to have a successful move. She even went above and beyond when our moving truck didn't show on the expected delivery date, loaning us some things so we could enjoy our first few nights in our new home. I would highly recommend Karen and the entire Coldwell Banker Scituate team (including Jeff Serowick) for your real estate needs.
We couldnt have made it through the process of selling our house if it wasnt for Karen! She was with us every step of the way.aEUR" especially when it got a little tricky at the end with the buyers financing. I cant thank her enough for her amazing positivity and guidance!
Karen was outstanding! She helped me decide what I absolutely wanted for my new residence. Her experience in seeing houses and pointing out some of the features as well as the flaws was extremely helpful in my making my final decision. You felt she was buying your home WITH you. I never felt any pressure. What was amazing to me was her professional attitude but she combined it with a warmth and friendliness. I was extremely glad she was in my corner!! I would recommend her and would be hard pressed to find anyone else of her caliber.
We had an Outstanding Experience with Karen Mullen !!Karen was very respectful of our needs and wants and did a GREAT jobKaren did a Great job with showings, and gave us good ideas to help us show our house
Karen was recommended to me by my sister who, no doubt, was a pain to have as a client. She spent months looking at dozens and dozens of homes and Karen was their every step going above and beyond to make sure her and her husband found the perfect home. When it came time for my family to look, we had one conversation with Karen and connected right away. Succumbing to age-old, battle tested sibling rivalry, I had to be a more difficult client than my sister. So Karen helped me buy a house in Duxbury, doing all the difficult work, mostly via Facetime and a long weekend of Nor'easters, while I sat comfortably at my current home in California. After finding the perfect house, she stepped in to help us close the deal while we stayed 3,000 away. LIke I said - she went above and beyond, did everything with a smile and made us happy with every step.
We will defiantly be referring Karen to family and friends. She is very knowledgeable of the market and offered advice when needed. She sold our house within a few days and made the transaction seamless. She also help us find a rental while we wait for our new home to be built.
Karen was a tireless worker, a true professional. She helped us with staging ideas, internal paint recommendations, etc. to facilitate the sale of our home. Karen's knowledge of the local market helped achieve a fast and full price+ sale between multiple buyers/offers. Her engaging personality and attention to details really put us at ease and at the same time instilled the utmost confidence in her abilities.
Exactly what you want in a realtor - Karen is incredibly knowledgeable, has strong connections, has high integrity, helps you think creatively and is unbelievablely responsive. She asks great questions to really help figure out what youre looking for. We would highly recommend her!

Karen provided excellent guidance, was incredibly flexible and accommodating, and had a deep knowledge of the marketplace. We are tremendously grateful for Karen's guidance and would not hesitate to work with her again or to give her anything but the highest recommendation.

Karen is in a word - amazing! When looking for our dream home we chose Karen as our realtor. She really listened to what we wanted in a new home and was thoughtful about her approach to showing us homes. She was always responsive, had all the answers to questions we had about towns, schools, features etc. My favorite thing about working with Karen is her phenomenal personality. She is so warm and friendly and just fun to work with. Buying a house can be stressful but Karen made it so easy for us as buyers. In the end, she found us our dream home and we couldnt be happier. I would highly recommend her to anyone looking to buy or sell on the South Shore.

We had a great experience with Karen Mullen as our Realtor, who helped us sell our home (in a few hours!) and buy a condo that is a dream. We highly recommend her.
Karen is an asset to the real estate community. She is very knowledgeable and extremely easy to work with. She knew exactly what needed to be done in order to put my house on the market. I needed to sell as fast a possible and Karen nailed to price and I got above asking. I would recommend Karen in heart beat to be your broker.

We met Karen in the fall of 2015 and have probably seen over 50 properties with her between then and our closing this week. She is patient, thorough, and quickly learns what her clients are looking for. Having known her for almost two years, we trust her completely, and now consider her more of a friend than our realtor.
Karen helped us sell our home within days so we could quckly place an offer on our dream home. Karen was instrumental in knowing the most recent market prices and sold our home competitively and worked closely with us the entire time with a quick phone call or visit away. Karen knew exactly what we were looking for in a new home and quickly found us our dream home and worked closely with us to place a competitive offer on the home. I highly recommend Karen as she did a terrific job in the selling and buying of a new home.
During a competitive sellers market, Karen helped us purchase exactly right house for my husband and my personality in exactly the right area! Without her negotiation skills, we likely would have not won the bid on the home. Many thanks to Karen for the outstanding job she did!
We had the pleasure of working with Karen Mullen on the purchase of our existing home in Scituate. She is a true professional who cares very much for the clients she serves. As newcomers to the area, she was a wealth of knowledge and continues to be a great new connection within our new community. We absolutely recommend Karen Mullen to anyone buying or selling a home!
