My Clients Say

  • 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 

    John Cowan

  • 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

  • Mary was extremely easy to work with and knowledgeable about all of the large and small details involved in listing and selling our home. She kept us informed at each stage of the process and was responsive to all of our requests. We recommend her highly.  Sept. 11, 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

    Bill D.

  • With Mary DeRose as our realtor we recently sold our Derwood home after only 3 days on the market! Ms. DeRose was very knowledgeable about our neighborhood and the housing market in general. She met with us several times to give us ideas about updates that would increase the value and desirability of our home. She also gave us great tips for little things that helped us prepare for listing. During the whole process – from listing to settlement – she kept us informed and answered all of our questions. We felt very comfortable with the outcome of our sale being in Ms. DeRose’s hands and highly recommend her! June 24, 2016

    Paul and Denise

  • Excellent agent. Was very interactive with us on suggestions to prep our home for sale. Everything from the large stuff (replace 11 year old carpet and painting) to the small stuff (suggested replacing the outlet covers to give it a nice new look with the new paint). Also helped us define a good price point to be able to move the house quickly to avoid 2 mortgages. Using her suggestions we were able to sell the house in 3 weeks. One of our open houses had 3 offers. July 16, 2016

  • Mary was excellent in helping us navigate through the new TRID policies when we bought our home. She is patient, professional and cares about her clients. I would recommend her to any of my friends.  Dec. 4, 2015

  • Mary DeRose is the realtor I used recently for downsizing from a townhouse to a two-bedroom condominium. During the fall of 2014, I had expressed to her an interest in downsizing. Mary took the time to help me decide what I really wanted in a new living arrangement. She found me a condo where both of us felt I would be comfortable. She became my advocate in the purchase process and arranged everything. As to selling my townhouse, Mary made several recommendations as to how best to set up my townhouse to look its best. I followed all of her suggestions. The photographer she used took fabulous pictures (once they saw these photos, a number of my friends asked me why I would want to sell such a beautiful house). The house sold within a day, and at a the price both Mary and I believed was realistic. She took care of all of the arrangements for the sale so that part of the transaction was also very simple for me. Mary knows what she is doing. She has been in this business for a number of years and has the contacts to ease any problems that may pop up. She was always available when I had questions and she kept me in the loop the entire time. I would highly recommend Mary if you are planning to either sell your home or purchase a home. I consider her as a top-notch realtor. Aug. 12, 2015

  • It was a great pleasure to work with Mary. She is very knowledgeable about the local market and knew exactly what was needed to get my Mom’s house on the market and sold quickly for a fair price. Her network of handymen did a wonderful job of preping the house for showings, at very reasonable prices. Mary had potential buyers in quickly and the house sold, for our asking price, within 60 days. She also did a great job of walking us through all the necessary paperwork and quickly communicated any important information. I highly recommend Mary. July 30, 2015

    Peggy O

  • Mary made many suggestions to help prepare the house for sale. Mary has excellent follow through and organization skills. The contract-settlement process was a breeze! June 30, 2015

    Susan B.

  • Mary was very easy to work with. Her response was immediate and professional. Her demeanor was very comforting and she listens very well to all concerns. She isn’t shy to make suggestions that will increase value and/or speed up a potential sale. She figured out exactly what I was looking for and delivered a buyer quickly. July 6, 2015

  •  I found Mary to be not only pleasant and professional, but also very kind, caring and considerate. We contracted with Mary to sell my mother’s house. Mom had passed away early in December of 2014. My sister and I are both out of towners, so the task of selling Mom’s house turned out to be a bit more complex than either of us anticipated. Mary was simply wonderful – she knew Mom’s neighborhood intamately, had an excellent understanding of the local market, and was able to recommend quality contractors to take care of all the little things that needed to be attended to in order to sell Mom’s house. Mary also went a little beyond what I would normally expect from a realtor, she truly took a personal interest in making sure Mom’s property was presented in a manner that my mother would have approved of. That extra effort to ask about features were important to Mom, and to highlight many of those features made what could have been a very emotional sales transaction a lot less stressful. Our family is deeply indebted to Mary for handling this particular transaction with so much personal attention. I would recommend Mary’s services to anyone who is looking to either buy or sell, and I am happy to say I have gained a new friend as the result of this business relationship. July 1, 2015
