    • This was by far the best experience I have had out of all the houses I have bought and sold. Sven is professional and honest about the listing price of your house.Andersen Group Realty helps to make the home sale process run smoothly and handles any obstacle put in front of them.

      - Daman C, Winchester
    • We had previously listed our property with another Winchester Realtor with no results.I then researched what Realtor had the most sales in Winchester during the past year and the Anderson Group came up.I could not be more pleased with their professionalism, support and results. The Andersen Group sold our home quickly and above the asking price. I give them 5 Stars. Thank you Andersen Group.

      - Susan S, Winchester
    • Sven and Andersen Group Realty were some of the most professional people with whom we have worked.They were attentive and respectful to our requests and needs and followed up on every activity/event to assure that we were happy and satisfied.Our house was sold in under 2 weeks!

      - Jack M. Winchester
    • My wife found Sven and Andersen Group Realty. I was dubious because I saw no reason to involve a Winchester agent who deals in multimillion-dollar homes in a Medford sale. (I wondered if we were a charity case.) Boy was I wrong!Sven Andersen did a walkthrough of our house. told us exactly what to do (and most importantly what could be ignored) and informed us he was going to generate a bidding war.The upshot was more than 100 visitors at our open house resulting in 19 offers and a sale substantially above our ask within five days. Every woman and man on his staff was absolutely responsive, understanding, and professional. They have my unequivocal gratitude and support.

      - Eric M, Medford
    • It was a pleasure to work with Sven and Andersen Group Realty.They were on top of every detail, oversaw a great deal of work, and managed a very tight process to sell the house within a short time frame.They really made the whole selling process extremely simple, especially since I was living out of state. I recommend them highly!

      - Anne E, Winchester
    • Sven and his team are epitome of professionalism when it comes to their craft. In a Boston market, with many economic and inventory constraints, they set out to make a personalized marketing plan for your home and your family. Each family is different, selling or buying for different reasons, and Andersen Group Realty handles all these familial issues with sensitivity, thoughtfulness and produces top flight results for clients in all phases of life. Not only would I recommend them professionally, but they are simply great people which qualifies the wonderful work they do in the business and in the broader community. This is a group committed to results while also developing relationships that enrich the communities in which we live.
