About Costello Group

My wife, Brandy, and I have been involved in real estate in some form or fashion since we were teenagers. We have worked in numerous fields inside of real estate and have a great understanding of homes and the home buying/selling process.

Real estate has changed our lives for the better and we enjoy positively influencing the lives of all of our clients, too. We have 3 boys and they are our "why" for this endeavor! Anyone that knows us, knows that our youngest, Carter, just might be with you from beginning to end. He loves going to closings!

We are not part of a large team, when you hire us... you get US! We don't hand you, your home or your file off to anyone else besides each other! We will be with you every step of the way! Of course we have a phenomenal team of professionals that we work together with that handle your transaction with the same care and attention to detail that we do!

As a teenager I worked in residential and light commercial construction and repair. While doing so I began working for a handful of investors and taking part in their renovations. Brandy began working in the appraisal field while still in high school and did so until becoming a REALTOR®. Brandy has a keen eye for the latest trends and designs. She will help you envision your new home or investment home no matter the current condition. We have combined this knowledge and experience to renovate homes for our own business, plus clients needing to sell. With this information we can help navigate you through the home buying and selling process to help you make the best decisions for you and your family.

Whether you're a seasoned investor, bought/sold multiple homes without representation before, looking for a second home, moving up/down, or first time buyer we are happy to meet you wherever you are in the process! We look forward to working with you!



I am truly grateful that I chose Mark to represent me. He made my home selling process go smoothly. He went above and beyond for me so he is more than highly recommended. Mark is the most professional, patient and amazing agent I’ve ever had. He really listens and he’s very thorough. He answered all my questions so I felt comfortable through the whole process, even after closing. I’m thinking, if only he was was a divorce divorce would have had better results.


Mark wasn’t was the first relator in the sale of my home, but definitely the best. Before contacting him, I had a really difficult and long sales process. My home was under contract to be sold, but it fell apart due to the incompetence of the previous relator. After the loss of the sale, it was time for change. When I contacted Mark he was very understanding and knowledgeable, but realistic about setting expectations. We had several conversations to make sure I understood the process, and to put me in a position to be successful in the sale of my home. Once I re-listed it, it was sold without a hitch. Without Mark, my house would still be for sale. I would absolutely recommend him to anyone looking to sell (or buy) a home. If you’re looking for a honest realtor, who will set you up to be successful... him and Brandy are the team to do it.
