More about Casey O'Neal

After 35 years in the real estate business I have learned that educating a client and building trust is the best way to overcome fears and apprehension. We treat our clients like family and friends, placing their interests’ first, combining honesty, competence and care. After growing up in an Air Force family and moving every year as a child, I settled in Arlington in the mid 1970’s. A few years later I met my wife Colleen and we have three kids and three grandkids. Both Colleen and I are musicians, and we have performed and recorded in various venues in the in the Washington DC area for over 40 years.

  • Casey listed and sold my home

      Casey and his team did a great job for us both buying our new home and selling our old one. This all took place right around the birth of our third child and it was great to have Casey and his team there to help us through it all.

    • Casey listed and sold my home

        I lived in my Barcroft neighborhood for about 40 years, and as far back as I can remember, Casey O’Neal has been a presence here, a neighbor himself who really knows all about this market! Over the years, I would get cards from Casey and, later, emails with information about real estate in the neighborhood and the county at large. Then two years ago I started working with Casey to get ready to sell my house. I did speak to another agent at the time, but Casey’s concern, knowledge and attention to detail convinced me that he was the right choice to take on my listing. We firmed things up last fall and I signed the listing agreement with him. He was clear with me that I needed to do some home improvements to get top dollar, so he made a list of projects and got me two bids. All through the reno process he kept up with progress, even pointing out some additional things that needed to be done. He arranged for a stager who did a great job making the house look its best. Casey put the house on the market on a Wednesday, held a neighborhood open house in advance of the public open house on Sunday – and I got a full price offer on Tuesday, which I of course accepted. Casey then guided me through the inspection and closing process which took place about a month after the buyers’ offer was accepted. Overall I was very pleased with Casey’s attention to the sale of my house – I always felt that I was the most important client he had and he gave excellent advice at many turns. I heartily recommend Casey to anyone looking for a great real estate agent who knows Arlington.

          During our first meeting Casey came well prepared with extensive documentation on properties recently sold in our area. His calm and reassuring manner as well as his honesty made us feel comfortable in relying on his advice. Given the circumstances we had to sell our house quickly and with Casey’s help we were able to sell within the agreed time frame and well above asking price. We were able to achieve these goals to a large extent because of Casey’s thorough follow up throughout the entire process. It was a pleasure to work with him. Casey did a wonderful job and based on our experience we would strongly recommend him to any prospective client.

            Casey O'Neal and his team have helped me through two house purchases and one sale and I am super pleased with the results. Casey came up with a successful strategy for preparing, staging and pricing my house. In the end, with a very small investment in repairs and staging, it sold in 6 days at a price significantly higher than I had imagined, but exactly in the range that Casey had predicted. Casey was patient and supportive through the whole process. I admire his combination of efficiency, competence and a low pressure helpful approach to working with his clients.

              Casey O’Neal and his team at RE/MAX Allegiance were amazing in helping us sell our house in South Arlington this summer. We moved out of the house in July to head across the country to our new home in Colorado. Casey helped us develop a strategy and lined up contractors to begin all of the renovations and repairs that needed to be done before our house in Arlington could go on the market. There were workmen in our house the day after we moved out! Casey oversaw everything—the landscaping, the floor refinishing, the installation of a new kitchen, the painting, the repairs, the finishing touches and the staging. He kept everything on track over the course of the six weeks it took to get it all done. Not only did he stay in constant contact with us, but he even went so far as to water the new grass almost everyday to make sure the newly-laid sod stayed green during the heat of the summer. Thanks to his efforts, we did not even have to return once to check on the progress of things. When he sent us the professional photos of the finished product, we couldn’t believe it. Our house looked amazing! His “Coming Soon” marketing produced hundreds of online views and many inquiries. His strategy was to go live on the market on a Thursday, host a weekend open house and set a contract deadline on the following Wednesday. We had a great offer, and we closed in less than three weeks! We first met Casey when we bought this house 14 years ago. While he was representing the sellers (people we knew), he was vital in helping us get our first house ready to put on the market and sold so we could get into this house. So when it came time to sell it, we knew exactly who to call. Casey came through for us—big time. We simply could not have done this without him. His efforts helped us get top dollar for our house. We enthusiastically recommend Casey O’Neal for anyone looking to buy or sell a house in Northern Virginia. ~Melissa B. and Stan C.

                Working with Casey O’Neal to sell our home was a great experience. Casey was knowledgeable of our neighborhood and the Arlington market in general. He was always professional but made himself available to us like a friend. Because of a job transfer, we had to leave the area while still finalizing minor repairs to prepare our house for sale. Casey was always available to help. The process was smooth and as seamless as could have been expected. I would recommend Casey and his team to anyone looking to sell a property in the area!

              • Casey helped me buy a home

                  Casey and his partner, Jennifer, were both amazing through the whole process. There were some kinks on the seller's end, but they helped guide me through the process very smoothly. I will only work with them for my next purchase. They have amazing knowledge of the area, do NOT use anybody else!
