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!



Purchasing real estate can be stressful and complicated, but if you’re lucky enough to have Mark as your agent, he makes it 100 times easier and QUICK. I was a first-time homebuyer and he broke down difficult processes into easy to understand language. He is accommodating, patient, flexible and ALWAYS available. Mark's honesty and wealth of knowledge was a breath of fresh air. Consider yourself working with the best in the business. I will only work exclusively with him from now on. He is also a good negotiator . He helped me save a lots of money on my purchase. I will recommend him any day, any time.

I have had the pleasure of working with Mark over the past year. I have had quite a Few real estate dealings and have worked with lots of other agents. I can tell you that Mark is by far the most punctual, courteous and knowledgeable people I have been around in his field. His attention to detail and willingness to go the extra mile and navigate through any issues is truly remarkable. He is always available for his clients. I think it would be safe to say that if a person is looking for a real estate agent that Mark is your guy. I am proud that I can not only call Him a business associate but a friend.
