    John is the best real estate broker I have ever met! This is the second time he's made our home transaction seamless and fast due to his ability to anticipate and address potential issues before they can even occur. We'll definitely be using John a third time when needed.

    John was upfront with what I could expect from the sale of my unit, and made the decision to sell an easy one. periodic emails with market analysis made me want to to sell because until I received the emails, I had no idea what, if any, I could profit. The whole experience was great, and I highly recommend John Callahan to sell your property.

    John found the unit for me when I moved to Lowell 16 years ago. He became a friend and neighbor and was my first and only call when I decided to put my unit on the market.

    John Callahan is the only person I would ever go to for property in Lowell, He's been wonderful to work with! John knows the downtown market better than anyone. John has worked with me for years, handling the rental of my loft before I sold it, and he's been fabulous to deal with. His colleague helped me locate reputable and reasonable service people to deal with preparing the property for the closing. Over the years John has introduced me to many reliable service people in the area who have helped me with home maintenance. I can't say enough good things about John. He has been honest, reliable, patient and good humored and has gone above and beyond to help me with the management and sale of my property.

    Having worked with Lowell Lofts and John Callahan before there was no one else I even thought of working with this time around. John is professional, knowledgeable, and trustworthy. He knows the Lowell market so well, that my home was not even on the market a week before I had an offer! not only did John sell my home but he provided me excellent referrals for an agent to work with to buy my new home in New Hampshire and a team of contractors who did an amazing job updating my home before moving in. He made the sell and buy process so easy, and I am so thankful to John for making it happen so quickly!

    John Callahan was extremely helpful and consistently on the case. He kept me informed in what turned into a complicated sale in the Covid environment. Couldn't have asked for better, more informative, and friendlier service. Will absolutely turn to John again when I am on the market.

    I had worked with John twice in the past: first when originally purchasing the property and second, when selecting a renter for the property. Both times I was more than happy with John's work! Though I have co-workers and other friends who work in real estate, I used John because of his specific knowledge and the unique requirements regarding my condominium rules as well as my previous positive experiences with working with him. John made the experience of selling my condominium completely hassle-free! John has an excellent knowledge of the Lowell Market. His communication is excellent and he is very responsive to questions in a timely manner.

    John Callahan had insight into the Lowell Mill Condo market that no one else did. He is the ultimate professional, very friendly, works tirelessly, and is everything I could ask for in an agent. He nailed down a sale for us with minimal open houses, in a short period of time and got us what we thought was a fair asking price. I would recommend John to anyone selling or buying Mill style condos in Lowell. He knew just about everything about the market.

    I really could not have asked for a better experience selling my condo. John made every step of the way easy and stress free. When I was concerned that maybe my listing wouldn't sell right away he made sure to let me know what we would be do and "next steps" in order to sell. My condo didn't even make it a full week on the market before I had an amazing offer. whenever i needed guidance throughout the whole process John was always available to answer my questions or just to listen if I had an issue! I highly recommend John Callahan and lowell lofts.

    John Callahan is an outstanding agent. I've worked with other brokers for properties in other areas and he is top-notch. He knows the market inside and out, had a well thought out strategy to maximize sale price and time to close, both of which were important for me. I highly recommend John to everyone looking to buy or sell property in Lowell.

    I knew John Callahan, whom I had worked with previously in the purchase of the property, to be an expert in the area and that he'd get me the best deal possible. Indeed, the property sold at full asking price, which was much higher than my expectations, within 3 days. John always responded very quickly to any questions that I had-- the service was very personal.

    John made this sale the easiest real estate transaction I have been through to date. John did whatever needed to be done quickly and professionally. I was never left wondering what the next step was. He was always on top of everything. He went above and beyond his responsibilities to make sure I got what I needed. Very little effeort was required on my end. His knowledge of the area is an asset. I had used John in the past to rent the unit. It never stayed on the market for long. He was always there to answer questions even long after the deal was done. I never considered using anyone else for my sale and I am very satisfied with the outcome.

    John is an excellent agent who is very knowledgeable about real estate in the city of Lowell.Therefore I trust his instincts for getting the property sold. I especially appreciated him arriving at my condo early one morning with ladder and hardware to work open my large condo windows that were painted shut. As a result of such dedication, the sale was finalized. I would highly recommend John for future real estate transactions.

    Ten years ago, when my wife and I purchaased our first loft condo In Lowell, John Callahan was our broker and helped us find the right place for us. It was a wonderful experience, so when we were ready to sell that same condo 10 years later, we didn't hesitate to contact John again. He is easy to work with, knowledgeable of the local market, and very quick to communicate any necessary updates. We would recommend John to anyone purchasing a condo in the Lowell area.

    I worked with John 6 years ago when I purchased my Condo. He was very patient and showed me many units through out the Downtown Lowell area. When I finally found the one I wanted the process could not have gone any smoother. When it was time to put the unit back on the market I never thought twice about who I was going contact. John is well connected in Lowell. He helped locate contractors to fix some minor issues with the unit. Since I no longer live close by, he went above and beyond the call of duty by also escorting them into the unit saving me from the 2+ hours of drive time to get over there. John also hooked me up with local, experienced Real Estate attorneys when I purchased and again when I sold. My unit sold in one day. Now there are no guarantees others will have the same mileage, so much of it depends on timing and I got lucky I needed to sell when the market happened to be hot. But I have no doubt in a slower market I still would have the best guy marketing the unit for me. The process was painless at each milestone along the way. I can't say enough good things about John. He's the man!

    This was a rental property, and over the years John Callahan has consistently come up with perfect tenants for me, every time. I couldn't have been more satisfied working with him. He knows the business, and is always available to help, whatever the situation. He's aggressive and hard working, yet a gentleman at all times. Throughout the entire selling process, he continued to amaze me with his efficient handling of every facet of the closing procedure. When the time comes, I look forward to working with John again with other property that I'll be selling.
