Whether she's helping families sell property or buy their first home, Mary takes the time to get to know her clients personally and listen to their needs to deliver the high level of service and results they deserve.

Many of those personal connections began back when she and her family operated the Hill High Orchards. "Families would come out to pick their own apples, enjoy the outdoors together and see how we made everything by hand, from pies to quilts," Mary explains. What she valued most about this experience, though, was getting to know so many of the visitors personally and watching their families grow over the years. Not only did Mary have an opportunity to work closely with her own family, but she welcomed others into this friendly, old-fashioned environment and formed lasting relationships.
Mary and her husband, of over 40 years, John, have instilled the same values in their own children and grandchildren, all of whom live in the area. These days, Mary enjoys spending time with three daughters and three great sons-in-law and her seven beautiful grandchildren, gathering her whole family together for a traditional Sunday dinner. She remains dedicated to giving back to her community, from sponsoring local 4-H activities, supporting the Children's Miracle Network, to supporting missionaries, Loudoun Food Bank, High School Sports, Cub Scouts, Girl Scouts and local churches.

What Clients Say About Mary Sleeter

Mary was very helpful through the entire home buying process and was very knowledgeable with any questions we had. I would highly recommend Mary to anyone actively or casually looking on the market. Whether you are a family with children, looking to invest, or in the second stage of your life looking for a home after retiring- Mary is very flexible to your needs, warm and inviting. I highly recommend her for your next purchase! Erick & Megan Guerrero
We have availed ourselves of Mary's positively superb service twice already, helping us to sell our homes in 2002 and 2017. Mary is the best!! Her depth of experience in the Loudoun County VA real estate market is unsurpassed, having lived and worked here her entire career and seen it grow and helped it develop from rural, agricultural farm country to be among the fastest growing and wealthiest counties in the country. Mary's experience is a capstone on her professional, responsive, and superior service guiding her clients in real estate assessment, estimating, pricing, financing, negotiating and being there at every step to not just get the deal done, but to ensure her clients get the best deal over-all; analyzing each offer and being able to discern the risks and potentials associated with each aspect of an offer, not just the bottom line, but each offer's subtle nuances that only an experienced agent like Mary would pick up on... Mary is patient, responsive, informative, friendly, considerate - the consummate professional - and a friend we would recommend to anyone looking to buy or sell (or rent) property in Loudoun County Don Fraser & Bernadette Sullivan
Thank you for the professional way in which you handled the sale of our house & property. Your optimism and assurance during the difficult times kept us going. This is the third sale you have handled for us and we high recommend you both to anyone who asks. We also want to thank Joy for being helpful in answering our questions and just being Joy. Jim & Kathy H.
I just wanted to thank you for showing me my house and to let you know that I absolutely LOVE living in this neighborhood. My one year anniversary will be next month. Hamilton Acres has a country like setting and is a quiet neighborhood. I have met some of the neighbors. Thanks again for all your assistance and helping me find my dream home. I love it here! Stephanie H.
As newcomers to Loudoun County, Mary Sleeter made our move from Arizona pleasant and uncomplicated. We were unable to visit the area twice and had to rely on our initial weekend trip. Mary spent as much time with us as we wanted, and when it came time to purchase a home, we were ready. We purchased our home by fax, with Mary's patience and professionalism, it all went smoothly. It was painless because of Mary. Whether your time is limited or you've got a year to make a decision, Mary makes it easy!! Diane & Dan P.
