“Sean O'Brien was absolutely fantastic to work with. He is easy to talk to, professional, responsible, and well versed in all the local nuances of Fairfax and Loudoun Counties. For the sale of my house, he represented me (the seller) as well as the buyer, and he pulled off the dual representation with consummate professionalism, protecting both sides' information and helping negotiate a deal that made everyone happy. The timeline on my purchase and sale was very short, and he was available at all times to facilitate the transaction and help us find a place that we love and answer our many questions about the house, the financing, and all sorts of other angles. I highly recommend him to anyone interested in buying or selling their house in the northern Virginia area. ”
