  • 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

  • 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

  • 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

  • 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

  • Mary was a huge help in finding a house that met my needs. She is an expert in the Potomac Rockville area and was attentive to every detail. She was a real asset to me in the process of finding a home. I would highly recommend her. April 30, 2015

  • My fiance Chelsea and I were so fortunate to be referred to Mary by a colleague of ours.

    She went above and beyond anything we could have hoped for in our Realtor. Mary was very attentive, learned what was important to us quickly, and focused her search based on those needs.

    We had a rather lengthy negotiation process, and without Mary advocating, as well as advising against certain suggestions from myself, we would not have the property we do today. Mary was always honest with us, even when delivering news we didn’t want to hear, while having our best interest at heart.

    Mary picked up on things within the property we never would have noticed and made certain those issues were addressed. She knew the area, and was tremendous when it came to diagnosing issues in the property itself. You can tell Mary’s level of expertise is beyond reproach.

    I speak for my fiance as well when I say we can’t thank Mary enough. She helped us realize a goal that we weren’t sure we would ever achieve in this area. It should go without saying that we would recommend Mary to anyone in the market. She is, quite simply, a terrific real-estate agent, and she has helped Chelsea’ s and my dream of owning a home come true. Thank you, Mary. – March 13, 2015

  • Mary priced our house perfectly to sell. She recommended a few tweeks that we did to the home and due to her recommendations the house ended up looking awesome. Her marketing skills are phenomenal – when we viewed the images of our house on her website we almost didn’t want to move (not exaggerating). We had an amazingly high number of viewings and the house went quicker than we ever imagined possible an for more money than we ever imagined getting. I recommend anyone buying or selling a home use Mary DeRose- she is extremely professional, witty, responsive, friendly, and easy to communicate with. I cannot say enough wonderful things about this realtor.  – Jun 11, 2014

  • Mary was wonderful!!!! She was very knowledgeable and helped us a great deal. She was a terrific advocate for us. I will, and have already, recommended her to friends and colleagues.- Sep 7, 2013

  • Mary redefined to me what it meant to be a great real estate agent. She worked tirelessly (and I can’t emphasize that enough) to help my wife and I both sell and buy. She was always available to talk, email or txt about what ever questions we had. Home buying is a complicated and emotional process and Mary was happy to explain and re-explain all parts as well as talk us off the ledge when the stress level got high. I would highly recommend Mary to anyone looking for an agent. We love our new house and have Mary to thank for it. – Aug 5, 2013

  • I am the Executor of an Estate and used Mary to sell a townhouse that was part of the Estate. Based on her experience, she recommended a good selling price and the house was under contract just a few days after it went on the market. She dealt with a lot of issues that came up in the negotiations and the inspection report in a calm and efficient manner. I never felt like I was “out of the loop” or that Mary was not representing my best interests. Not only would I recommend her, I already have made one referral to her. – Feb 10, 2013

  • Mary worked with us to sell my father’s house after he passed. It was a difficult time for us and she guided us through every step of the process. Mary’s expertise shined through in appraising the property and ensuring it was priced appropriately. Her deep understanding of real estate, anticipation of buyer’s demands, and exceptional negotiating skills provided us a result that exceeded our expectation. I would not hesitate to recommend Mary to my family and friends. – Nov 10, 2012
