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!



My wife and I cannot say enough great things about working with Mark to buy our first home. He is knowledgeable, professional, honest and accommodating. His zero pressure approach to the process was absolutely refreshing especially since this was a new experience for us. Over several weeks, he took the time to show us around to about 10 properties until we found the perfect one that fit everything we were looking for. He took the initiative to research each one prior to our meetings to give us the facts as well as his personal opinion. We learned throughout the process that he had experience with home construction so his opinion was something we came to trust and count on. We also learned that he is a former LEO and let me tell you that his integrity shown through with each communication and meeting. Speaking of communication, his is top notch. He was always reachable whether it was via phone call or text, whatever worked for us at the time. He would also contact us immediately with any news or direction but never to the point of pushy or over-reaching. Again, refreshing. He even reached out to us again two weeks after our move in date when a strong storm came through the area to see if all was well and inquire if we needed any assistance with damage remediation....seriously! To speak to his knowledge and experience, we ran into a couple of speed bumps with the seller during negotiations and under contract, the worst of which was the point when the seller tried to back out of the sale the Friday before our closing date (following Monday)! He was able to instill into the seller's agent how bad of an idea that was a that point, taking into consideration the legal action available to us contractually. Suffice to say, the seller came back around that weekend and the Monday closing date was back on which went on without further hitches. Another super convenient aspect is that he works closely with a lending partner in Luke Hamlett of Supreme Lending. They worked hand in hand throughout the process to help us get into a house that fit the price and payments that we had budgeted for that checked all our boxes. In the end, he worked to get us into our turnkey, 3 year old, 3 bdr - 2 bth house that fit our every expectation and needed nothing! Side note, he had all the contacts that we needed to complete each step of the purchase (home inspection, appraisal, home warranty, etc...). I know that there are many more examples I could provide but in the interest of keeping this "less lengthy", I'll end with this. You will be hard pressed to find a better agent to help you buy or sell a home. We will undoubtedly look to Mark again when it comes time to sell this house and move on to the next. 1,000 thanks again for all you do Mark!

We met Mark by happenstance when we stumbled into an open house a year and a half ago.  We weren't ready to make the move yet but we had a great conversation and felt like we had made a new friend.   When we had decided it was time to make the move to Texas we initially enlisted the help of a family friend who is a realtor part time.  After some discussion and advice we realized that we needed someone full time and the only person we wanted to give our business to was Mark.  That 10 minute meeting a year and a half before had stuck with us and we knew we could trust him to handle our out of state move.  We contacted Mark and were shocked to learn he remembered us!   We had a 20 minute phone call with him where we gave him our "needs" and "wants" and he went to search.  We received several emails a day with possible homes and he was constantly at our beck and call for answers to questions and odd requests.   We came to town, he picked us up at our hotel and happily drove us around, answering all our questions and showing us homes.  When we found the one we loved there was no question - we just knew - and Mark did too!   We put in the offer based on his expertise of the area and after a couple negotiations the offer was accepted.  We were already back in Arizona dealing with a family emergency when the offer was accepted and Mark did all the work for us.  It was truly like putting our trust in a family member - not a realtor we had only spent a few hours with.   He took the time out of his schedule to go to the house for all our inspections, appraisals and everything that needed to be done since we couldn't be there.  He put us in contact with Luke Hamlett at Supreme Lending - who was another incredible experience.  We trust these two gentlemen with everything and will recommend them to everyone we know and will use them again ourselves if we ever decide to move again. Mark is truly one of a kind.  A brother.  A friend.  I would highly recommend him to anyone buying or selling a home.
