I have worked with Jim for many years to buy and sell properties in Baltimore. Jim researches area comps and sales to help me get the best price. He is honest and trustworthy which is why I continue to work with Jim with my real estate transactions. He is very communicative and responsive to my calls, questions and concerns.

Choosing the right real estate agent can make all the difference, and for us, that difference was Jim Gunsiorowski. After a disappointing first home-buying experience in 2019, we knew how important it was to find an agent we could truly trust for our move to Baltimore. We interviewed five agents, all of whom were good, but Jim stood far above the rest. What sets Jim apart is his rare combination of expertise and character. Working with him felt like getting a real education in Baltimore, row homes, and the home-buying process. Our first interaction with Jim was in 2024, when we visited Baltimore for a long weekend and toured over a dozen homes with him. With our very short time frame, the right home just wasn’t on the market yet. Still, Jim earned our trust by never pushing for a quick sale and by taking the time to understand what we wanted so we would be ready when the right opportunity came along. When we returned to the market in 2025, there was no question who we would call. Jim got us showings right away and helped us look beyond first impressions to decide what truly fit our needs. The Locust Point and Riverside markets were extremely competitive, but through Jim’s connections we secured our dream home with one of the city’s best builders. With a tight closing window on our end, Jim worked tirelessly, coordinating with all parties to make sure we closed on time. Every professional we encountered along the way told us, “Jim is the best,” and we couldn’t agree more. Jim’s dedication didn’t stop once we went under contract. He attended every in-progress review with the builder, something the builder himself told us he had never seen another agent do. His presence was always reassuring and perfectly timed. He knew when to step in with advice and when to give us space. That sense of judgment and care made us feel consistently supported. Jim exceeded every expectation by balancing expertise, integrity, and genuine care for his clients. Thanks to him, we are in a home we love, and we couldn’t recommend him more highly.

We bought our first home in May 2025 and are so grateful we had Jim by our side. From the start, he was down-to-earth, patient, and incredibly informative—teaching us so much as first-time buyers. Jim knows the pulse of the neighborhood, has a strong network of local professionals, and was always responsive and available (even after closing). He listened closely to what we wanted and guided us with care every step of the way. We would highly recommend Jim and the Key Group team! Thank you Jim!

Working with Jim to buy my first home was an absolute pleasure from start to finish. As a first-time homebuyer, I had a lot of questions and uncertainty, but Jim made the entire process smooth, clear, and enjoyable. He was incredibly knowledgeable, patient, and always available to answer questions or explain the next steps. Jim truly listened to what I was looking for and never pressured me — instead, he offered honest insights and helped me weigh the pros and cons of each property we viewed. His attention to detail, professionalism, and deep understanding of Baltimore gave me total confidence throughout the process. Most of all, Jim genuinely cared that I found the right home. Thanks to his guidance and support, I found a place I love and feel great about.

Jim and his team helped me sell my condo in Federal Hill and I highly recommend them to other sellers. I was given a very clear step by step overview of the process and timeline and thus felt assured throughout the transaction that he was on top of everything. I really like how responsive and accessible Jim was to any questions and he was confident and gave good advice on how to handle some items that had to be negotiated with the buyer. Jim and his team also went above and beyond in assisting with my ability to get this done while I was out of state dealing with family medical issues. I also appreciated Jim's knowledge of the local market and how to price my condo so that it we would obtain an offer as soon as possible.
