"Working with Katherine Bell has been truly a delightful experience. At the end of 2021, Katherine managed the entire process of helping me buy & sell in the South End - and made the process seamless. Somehow she was always available and worked with my unpredictable schedule. Katherine also comes to the table with a vast network of lenders, inspectors, lawyers, etc. all of whom have nothing but incredible things to say about her. I can't recommend Katherine enough. " - Buyer and Seller, South End

"We were trying to sell our place in Beacon Hill - and Katherine did a phenomenal job. We were under some time pressure as we were moving + needed the home equity for another purchase, and Katherine set up several great showings within days of listing (including a few before official listing). Not only did she help sell our place for a great rate - but she went above and beyond in helping ensure everything was perfect during our close process. While we were out-of-state, she proactively coordinated cleaners and helped with logistics for a few small fixes. 10/10 - wish we could bring her with us to buy/sell in California! " - Seller, Beacon Hill

"We had a truly wonderful experience working with Katherine! It was our first time buying a home and she made the process so easy, from the moment we started our search until even after we had already closed on the house and moved in. Katherine is a pleasure to work with, has a keen eye for details, is impressively knowledgeable, and is as proactive as she is responsive. In short, she worried about everything so that we didn't have to. We love our home so much, but if and when we ever move, I know exactly whom to call. I could not give her a more enthusiastic endorsement!" - Buyer, Scituate

"Katherine was great! She was attentive, responded quickly, answered all my random questions as a first-time home buyer, and actually listened to what I was truly looking for. She was able to also provide additional properties I hadn't come across yet. Besides being knowledgeable of the area, Katherine was available to advise and put me in contact with who I needed. She is incredibly organized and prepared too. I have and will continue to recommend Katherine!"

"Katherine worked with my fiancé and I for 4 months starting late December 2018 and helped us find our home (a condo in Somerville which we LOVE!). She is extremely knowledgeable, helpful, kind and easy to work with. We spent most Saturdays with her for months in a row, seeing homes. We took our time, seeing different types of homes in different areas to figure out what we wanted. She was patient and helpful the whole way. She offered advice when solicited but also let us sort out our own preferences and priorities in a home without rushing or pushing us in a certain direction. She was an absolute pleasure to work with. In fact, we kind of miss spending our Saturday’s home searching with Katherine :) "
- First Time Homebuyers, Somerville, MA

"Katherine dealt with me (a very difficult and choosy client) who was incredibly frustrating to manage with class, elegance and persistence. After we saw a bunch of places, she found me the literal perfect spot. I am so grateful she knew so much about off-market listings. 2 thumbs up - KBell is the best. Strongly encourage."
– Renter, Downtown Boston

"Katherine has a great knowledge of the city and her clients allowing her to provide real estate options that best fit her client's needs. She is amazingly quick with her responses and helps guide you from the start to the finish of the process. When planning to make an offer, she provides great advice on what kind of offer you should make and dealing with negotiations. I'm so happy with the place I'm in and I owe it all to Katherine!"
– First Time Home Buyer, South End

"Katherine was wonderful to work with and helped my husband and me find the perfect Boston apartment. We are beyond thrilled with our new home! She conducted very thorough research to show us apartments that exclusively fit our requirements and was reachable at all hours of the day. She was also very accommodating of both of our work schedules which was a huge help. In addition, she is a Boston native and offered us great insights throughout the entire process. Katherine was professional and positive and a true pleasure to work with."
- Renter, South End
