Madison Collum, Global Real Estate AdvisorAs newcomers to Florida, we leaned heavily on Madison and he exceeded our expectations. Very reliable and personable, he offered deep knowledge of the area as he grew up in West Palm Beach. Always quick to respond, he went the extra mile on multiple occasions to get every detail just right. We trusted him completely.

Madison Collum, Global Real Estate AdvisorCan’t say enough about Madison first as a person, second as a realtor. Professional, smart,, easy to work with and gets the job done. Sold my house in a little over a week. Would trust him either buying or selling a property. If I need a realtor in the future, Madison will be who I call.

Madison Collum, Global Real Estate AdvisorDear Madison: We want to thank you for your professionalism, knowledge, friendship and effective approach that was instrumental in selling our home. After having had the house in the market for a long time, we switched to you and your One Sotheby's International team and the difference was notorious. We were thrilled with the friendly and knowledgeable approach that allowed for multiple showings, always quick feedback and updates and 24/7 availability to answer texts and emails that made us feel confident and comfortable. All the steps, including the recommended real estate attorney and your interaction with the buyers and their agents were flawless and helped the whole process from listing to closing go very smoothly in the best way. We can recommend Madison McCollum and the One Sotheby’s team without hesitation as the first option for Real State in Palm Beach County.

Madison Collum, Global Real Estate AdvisorMadison absolutely went above and beyond! Being out of town for the entire process, we were so appreciative of his handling of all of the contractors, remediation, crazy neighbors and staff, and all of the other issues encountered in order to get this property sold. The tasks that needed to be addressed with the property were very time consuming and maddening at times, but Madison handled them on our behalf with patience and grace. We know that not many realtors would have handled everything that Madison did for us. We are grateful as it took a burden off of us and we thank him from the bottom of our hearts. More importantly than his skill, competence, and tact as a realtor, is who he is as a person. He is genuinely kind and a wonderful human being, with laundry and decorating skills to boot! We were so fortunate to have Madison represent us and to have gotten to know him as a friend during the process.
