My Clients Say

  • Mary was outstanding at helping us sort through the many options when establishing sale price and marketing strategy. Her knowledge of the marketplace and climate was very evident. She made a very workable recommendation that yielded top dollar. She is all business with a highly professional approach while also providing a warm and friendly manner. She was very responsive and answered all of our questions in a precise and concise way. Working with Mary was a wonderful experience and we were extremely pleased with the process and outcome.

  • Mary did an amazing job helping me purchase my first home. Going through the home buying process during COVID was quite an experience but Mary helped me remain optimistic every step of the way. She is a pro! She helped me research and really determine what types of factors were important to me, and which things I could live without. Mary always gave me a dose of reality about other comps and why the market is the way it is right now. She has amazing customer service and worked hard on my behalf with third parties involved in the process when they were slow to respond or didn’t provide a sufficient response. Mary will do everything possible to advocate on your behalf, which is such a comforting feeling when parts of the process feel overwhelming or challenging. A great example of this was the pre-loan qualification process and then the final portion to have all my ducks in a row right before my closing date. She helped make sure I knew what documents would be expected and why the underwriters needed specific details. Mary isn’t an underwriter but she has so much experience she “gets it” and can convey the underlying rationale to her customers. I’ll put it this way – if you were a famous movie star, Mary is a top-notch agent representing YOU. She makes her customers feel like priority #1 all the time. She will answer any question or help with a problem day or night, around the clock, and always with a positive attitude. Mary is dedicated to her career and will not let you down. She knows the market and current trends, and networks with her peers and other vendors who work in the business. Her ability to combine all of these elements makes her a force to be reckoned with!! You won’t regret selecting Mary DeRose to help you buy your next home. ??Sept. 27, 2021

  • “Mary has so much knowledge in the home buying/selling experience. She’s patient and understanding, and also knows how to get all the tasks done with the other agents. She was always available for questions and information and she was dedicated to finding the right home for us.” May 2, 2020

    Mike C.

  •  “I loved working with Mary. She was great at communicating throughout the process and very responsive when I had questions or concerns. She is very knowledgeable about the local market and gave me solid advice about staging and pricing up-front, and throughout the various stages of offer negotiation and sale. She was unflappable but thoughtful, which really helped minimize my anxiety through what is just objectively a stressful process. It was a pleasure working with Mary and I highly recommend her.”

  • I highly recommend Mary DeRose. This is the second time I’ve worked with her and I chose her because of my positive first experience. I recently purchased a house in Rockville with Mary as my agent. I started my search in a rather broad area and narrowed it down. Although Mary knew I wouldn’t be happy in some of the areas I initially decided to look in, she was patient with me and showed me what was available. When I began to focus on the area I eventually bought in, she kept daily tabs on the new listings in my area and price range and helped me narrow down my choices based on the features most important to me. Mary also sold my house in Potomac. I prepared it for the market shortly after settling on the house in Rockville and moving in. Not only did Mary work with me to make sure my house would show as well as possible, but she was also practical and flexible about pricing advice. The house sold relatively quickly. Throughout the process, Mary was extremely professional and had good relationships with the other professionals–realtors, brokers, financial personnel, etc. I recommend Mary without hesitation.  Dec. 6, 2018

  • Mary was awesome and did an outstanding job selling our family member’s home long distance. She was instrumental in working through some difficulties with confidence and expertise. Nov. 15, 2018 

    Michelle C.

  • Mary was extremely professional and experienced. . What was particularly impressive was she was so proactive – she alerted us to issues and handled them before they became a problem. I also really liked the photos taken, especially the aerial photos of the house. Even though we were living out of  state she constantly in touch, informing us of the progress of the sale and what was going on. Mary is also a very pleasant person to work with. She more than earned her commission and I highly recommend her. Oct. 31, 2018

  • Mary worked with me from the time I had to make the decision to sell and downsize. Very knowledgeable in the real estate business. She made recommendations for things that would help the curb appeal as well as some for the interior appeal. She is personable and did not take offense to my “no”  answers. I have already recommended her to others. She also helped me find my new condo and understood how hard the decision was. Always had my back. Kept me involved in all transactions and went out of her way to make herself available when I just needed someone to talk to or panicked. It was a pleasure working with her. Thanks Mary  April and June 2018

  • I want to give a huge shout out to my real estate agent, Mary DeRose Davis! My new welcome mat is the epitome of what she is all about…she is so thoughtful and giving!!! She had the mat waiting for me at my new house, and when I saw it… I lost it!!! I was so overcome with gratitude,  excitement, pride, and joy! Mary was by my side every step of the way…she is caring and patient…But, she can also be fierce when it’s time to have your back!!! She actually came to my house and helped me pack my boxes, she came and supervised painting and then staged my house perfectly while I was away in Hawaii…and she helped me find my dream house!!!?????? She kept me on task and made sure nothing fell through the cracks, so both closings were smooth and easy…and actually kind of fun!!! Mary, thank you! Thank you for going above and beyond during this journey… I couldn’t have done it without you! I know Quincy, Crosby, and I are going to be deliciously happy in our new home!!!!  Aug. 16, 2018

  • Mary is extremely knowledgeable about real estate in the DC metropolitan area. She knows just how and where to market and was very successful in selling my condo so quickly! I would highly recommend her for any of your real estate needs. She’s also just great to talk to! February 21, 2018

  • Mary was fantastic and helped me sell my 11-year-old condo in just a few weeks. She got me the price I needed and helped me get it ready to sell at a minimal cost. She handled everything for me and negotiated a great price for me when the buyer’s tried to offer me less. She knew exactly what my place was worth and made sure I go that amount. She is highly professional and easy to work with. I would give her my highest recommendation. December 10, 2017
