What my clients are saying

Mary Kate is great to work with! Was selling my mother's house to close her estate. I live 130 miles away. MK was an awesome help with handling details on that end. She connected me with a tradesman to refinish floors and other small details. This sold the house. Had a firm offer, above listening price, in three days!

Mary Kate was fantastic in every aspect. She did a great job in showing us potential homes in the area we wanted to move to. She also helped us sell our old house quickly at an excellent price. Mary Kate did a great job accommodating my wife's health issues. We have maintained contact since these sales.

Mary Kate was an awesome & most professional realtor. She handled a very complicated transaction between us (heirs of the estate), a most difficult law firm & a less than helpful property management group. Her ability to navigate through the parties was MOST impressive. She went ABOVE & BEYOND her job reaching out to other mortgage companies (for the first buyers) to help out, trying to get the DUCOIA paperwork corrected and assisting us with the law firm’s issues on pricing concerns. Mary Kate was always available via phone & text and kept us (sellers) in the know the whole time. Her services were well worth more than TWICE what she was paid at settlement. Remax is lucky to have such an amazing woman ion their team ! I would will recommend her services HIGHLY to anyone needing a realtor! Mary Kate I cannot thank you enough for your persistence, determination and dedication to helping us sell out inherited house. KUDOS to You!
