Working with Katie Tully & Clay Tappan to sell our home was an outstanding experience from start to finish. They sold our home quickly and handled every step of the process with complete professionalism. Katie & Clay kept us informed throughout, clearly explaining each stage and what to expect as we moved toward closing. Their communication, expertise, and steady guidance made the entire experience smooth and stress-free. We couldn’t be happier with the results and highly recommend Katie & Clay to anyone looking to sell their home.
Working with Katie was truly exceptional. She has known for years how much we love our current home, so when she reached out about a nearby listing that might better suit our family’s needs, we were a bit surprised, and incredibly grateful. She saw something in this home that we hadn’t even considered: a bit more space, more character, and a charm that fits our family perfectly. Because the home was being sold by a builder mid-renovation, this purchase was far more complicated than any of our previous real estate experiences. Katie guided us through every step with patience, organization, and an incredible attention to detail. She kept track of all the little things that could have easily slipped through the cracks and made sure we felt informed and supported throughout the entire process. We truly wouldn’t be in our new home without her insight, advocacy, and care. Katie is not only an outstanding realtor, she’s a trusted friend who always had our best interest at heart. We’re so grateful for everything she did to help us find the perfect home.
