"We bought our first house with Tammy as our buyers agent in the 1997 and just completed our second purchase with her. She is not only extremely knowledgeable about the local housing market, but is a joy to work with. We were always confident that Tammy had our best interest as her goal, no matter how many houses we needed to see before finding the right one. Tammy has our highest recommendation." -Heidi

"Tammy was my agent in purchasing my home in 1995 and so it was not surprising she was my first choice to sell it 25 years later. We decided to sell and relocate to our second home full time outside the DC area when we realized that traveling for work had ended likely for years. What Tammy brought as a trusted advisor was a strategy on pricing, staging, landscaping and the sales process that yielded a very quick sale significantly over our fair asking price. Tammy helped us not only through the process and the transaction but some of the inevitable emotional hurdles in selling a home you have lived in for so long. I would strongly recommend Tammy Gruner Durbin to anyone buying or selling a home." -Sam

"Tammy Durbin is a true beacon of light in a very competitive, complex real estate market in the DMV area. There are not enough stars to do justice to the glowing recommendation she deserves. They say moving is one those major life events that truly causes people undue stress. Buying a condo in Montgomery County and then changing jobs and selling it the height of the pandemic was an incredibly difficult thing for me. Tammy helped me navigate every step as if my problems were her own. I am a teacher and despite a tight budget, she helped me take each step, slowly yet confidently, making all things seem possible because, in the end, under her guidance, they were. She truly walked the journey with me, constantly offering sound advice on everything from mortgage insurance, title companies, negotiations with other agents, and even the woes of working with the Montgomery County government. She approached all aspects of the process with efficiency and grace and even shielded me from some of the added stressors that arose during negotiations between agents. No detail was left unturned. There are actually not words to describe just how incredible Tammy is. She is the person you want by your side when walking through any real estate adventures. Her knowledge, expertise, wisdom, and “get-the-job-done” mentality cannot be matched." -Sarah

"Thank you Tammy! Selling our house in the beginning of a global pandemic was an unknown and Tammy provided the most spectacular virtual tour of our home that facilitated a sale with multiple offers within 6 days of listing! Tammy coordinated all the closing tasks with ease and grace and made the entire process less stressful than I ever would have imagined. I would highly recommend Tammy for her real estate knowledge, commitment to her clients, tenacity, and grace." -Julie.

"Tammy was recommended to us by a trusted friend and we were so grateful for the recommendation. Moving to the DMV from New England, we came to house hunting in Maryland without a great deal of familiarity of the various neighborhoods, typical housing stock in each area, and the benefits and resources available to each area we explored. Tammy was a terrific guide and helped us not only find a wonderful home, but get oriented to the area. She was also really easy to work with, from afar, and was very accommodating to our schedule when we were able to be in the area to house hunt in person. To help us get oriented, we saw many houses and she was always patient and cheerful with us. We can't recommend Tammy enough. Call her today!" -Dan and Maria

"Tammy is an amazing agent and we highly recommend her. She is highly organized with a strong plan. We had four strong offers and signed a contract for more than the asking price within five days of listing! We met with Tammy when we were first considering selling our home. She walked us through all the steps, explained her plan and told us what to expect. Then we walked through our home are were given suggestions on what adjustments/fixes to make. She recommended good contractors to do repair work and would have acted as project manager if we needed it. She recommended staging which really highlighted the best features of our home. She also brought in other brokers to get their opinion on the asking price. Importantly, she understood our anxiety as we were preparing to sell and worked to calm our nerves. This woman is top notch and we could not have been happier with her service and with the result." -John and Sharon

"Resourceful, thoughtful, efficient and kind , I highly recommend Tammy Gruner Durbin. Moving in a pandemic was not easy, Tammy made the journey pleasant and effective (great negotiator! we found a house! we did not over pay! we closed on time!) In addition, being on Team Tammy meant she was with us right until the end. She provided sage advice regarding mortgage, insurance, title companies and even designers. Prior to our move, she remembered to send us information on utilities, cable, internet and more so we would not have to have a lapse in service. Finally, when we arrived at our new home, there was a beautiful orchid waiting for us - the perfect ending to an exceptional experience." - Amy

"After more than 22 years of living and working in Asia, I decided to relocate to Washington DC. A colleague referred me to Tammy, who immediately contacted me to inquire about my home search needs. Based on my response and my special circumstances (relocating with 4 pets and not knowing the Washington DC area), she was able to identify properties for me to view and she set up visits for me during my short trip to Washington DC. Tammy actively engaged with me, and patiently and knowledgeably guided me from the initial housing search through the closing process. She made sure that all deadlines were met, and tirelessly stayed on top of the process. This was especially critical since for most of the process through closing I was out of the country. Tammy was always available, responsive to my queries, and provided excellent advice and guidance. I also very much appreciated her calmness, professionalism and dedication to get the job done from start to finish and am extremely thankful to her for my new home and for a very smooth and seamless process. I highly recommend Tammy to anyone looking for a new home in the Washington DC area." - Donneth

"Although I generally do not make public endorsements, we are so impressed by Tammy and our home sale process that I will gladly share our experiences with you! I will start by saying the Tammy is a professional, knowledgeable real estate agent. Her instincts are accurate. Her demeanor is always calm, thoughtful, and open. She is a great listener! Tammy develops a game plan that balances the current real estate market with her buyers needs. Because of her talents, we were generally calm and comfortable, a feat for any real estate transaction. We recently sold our house during the height of COVID-19. Because of this major international crisis, all real estate transactions became more complicated, stressful, and messy; never mind that there was no precedent for predicting buyer's reactions. Since our initial meetings with Tammy occurred before COVID-19 became high profile in our area, the timing of our home sale gave us the opportunity to watch Tammy adapt in the most challenging circumstances. Tammy's marketing strategy respected the complex needs of a large moving away from the Mid-Atlantic region during an international pandemic. With great success: We put our home on the market at the beginning of the month. Three days later, we reviewed and ratified one of several contracts. And we closed before the end of that same month! We will be relocated to our new home within 3 months of the day our house went on the market. " - Judie

"Tammy did a fantastic job in helping us sell our property. Her professionalism, integrity, dedication, responsiveness and tremendous knowledge of the real estate market in the area were key to a successful and pleasant experience. She is a very seasoned real estate agent and was available around the clock to provide answers and referrals for anything we needed in order to position our home for selling. Tammy advised and helped us through every stage of the process, from preparing the property to go on the market to closing. Her guidance on the repairs, painting, landscaping, and staging was critical and her marketing strategy was excellent, resulting in multiple offers in only 3 days without an open house. The property sold above the asking price and closed quickly. We highly recommend her!" - Maria

"I highly recommend Tammy - her knowledge, hard work and professionalism resulted in the successful sale of my property. Tammy’s 30 years’ experience proved to be invaluable, as she was able to immediately answer my questions and recommend effective solutions during a volatile market. Her efficiency resulted in a quick sale, because she was timely and diligent in preparing research, setting up all phases of the sale, and quickly responded to all inquiries. Tammy was very professional and worked well with all parties involved in the selling process, making the experience stress-free. Thank you so much Tammy!" - Brigitte

"Tammy Durbin did a marvelous job of helping us find our new home in a search that took over six months. We had a very particular set of criteria which did not phase her at all. She toured multiple houses with us, and eventually we found exactly the right house. Her guidance during the bidding process was excellent. She was right with us the whole way from the inspection and the contractor visits to the closing. " - Elaine

"I have staged homes for Tammy's clients periodically over the past five years. I have been able to watch her work with her clients and highly recommend her for those who are looking to sell their home or buy new. She is passionate about her work, meticulous and consistently goes above and beyond for her clients. Additionally, when I was interested in a real estate investment, Tammy spent time taking me to properties, forwarding information and offering sage advice." - Tyler

"Tammy OWNS Sumner. She is a consummate professional. Everyone who uses her is happy with their results. If you want to hire someone who is devoted to buying or selling real estate, contact Tammy." - Mark

"We first met Tammy Durbin when she showed an open house which we ended up purchasing. Later, when we needed an agent to sell our home of 36 years, Tammy was the obvious choice. In all aspects of representation, she proved to be knowledgeable, professional, thorough, and responsive to our needs and concerns. We would recommend Tammy to anyone ready to buy or sell a home. " - Diana and Albert

"We were so pleased that we had Tammy represent us. Due to Tammy's professionalism, real estate expertise, and her ability to provide great customer service, we highly recommend Tammy to anyone interested in buying a house." - David and Courtney

"Tammy was recommended to me by friends of my sister. I live in Calif but had to sell a house back east in Bethesda MD. I was very worried about how was I going to do that! I knew I would need a kind and patient realtor, that was going to have to do some extra work without a seller present.Tammy was truly fantastic and made it easy for me. I had also never sold a home. She laid out repair and pricing issues simply for me, helped me make decisions, and guided me in those decisions.In retrospect she was completely correct with her thoughts on the issues, and her recommendations. I followed her recommendations and the transaction went just as she predicted, and was over quickly and smoothly.I highly highly recommend her in every way! Thank you Tammy!" - Janet

"Tammy Durbin helped us make a major smooth transition in our lives, when we moved from our long term home in Fort Sumner, Bethesda, to a near-by condo. We found her knowledgeable not just of the real estate industry but of Bethesda and surrounding communities. She was immensely helpful at every step of the sales process, directing us as necessary to other service providers from staging to mortgage companies. She was available to accompany us to showing and to write contracts at hours that suited a working couple. She is practical and helped us be realistic both in pricing our home and in placing offers. She remained on our side while helping us recognize possibilities and constraints. She is well connected to local realtors and as a result is very much on top of what’s for sale and what may be coming on the market. As a result, we bid on our new home before it was shown to others. Tammy is also perseverant and patient – with us it was probably long-suffering. From the time we began looking for a new home to our final settlement at least three years passed. We remain very grateful for her help. " - Burt and Anne

"Tammy is an outstanding real estate professional. She understands the market and what it takes to sell a house. We were not in town while our house was on the market and she took care of everything in our absence, including preparing the house for sale and supervising repairs. We put our house on the market during the Thanksgiving/Christmas season, which was probably not the best timing. However, she told us to be patient and we eventually sold our house at a great price. I would highly recommend her, especially if you live in the Fort Sumner area. She is someone who you can trust to give you honest advice and will do everything necessary to sell your house at the best price. She earned every penny of the commission we paid her. " - Renie

"We were extremely pleased with Tammy Durbin's very professional services as our real estate agent in the selling of our home in Ft. Sumner at 5044 Westpath Terrace. Tammy Durbin's expertise was invaluable in every detail up to the final sale. It was excellent considering the market was at its lowest rate at the time. We would highly recommend her for her attention to detail and a strong personal empathy to our needs until we moved to Maplewood Park Place, a lovely retirement community in Bethesda. " - James

"I cannot recommend Tammy highly enough. She sold my childhood home in Fort Sumner after the passing of my father. She took a genuine interest in the history of the house, and was sensitive and respectful in making beneficial recommendations to help improve its marketability. Additionally, when we had some challenging moments with one contract, Tammy went above and beyond her job as my agent. She was a steadfast and persistent advocate for my best interests, and I remain most grateful for her efforts. Tammy is a class act and true professional. I would use her again in a minute. " - Donna

"We sold our house and bought a new one with Tammy: what a great experience! She is knowledgeable, experienced and hard working. I would highly recommend her to anyone needing a real estate agent. " - Alex

"I adored working with Tammy. My husband and I are so grateful for all that she did to get our house ready for sale and then to sell it. It was complicated, due to an international move, and she handled it all. The bottom-line is that Tammy really knows her "stuff." Everything was first- class and well done. She is also personally such a delight to work with and was 100% available to us. " - Alisa

"Tammy did an awesome job for us selling our home in Sumner. She is very professional and knowledgeable about all aspects of the business and truly a delight to work with. We were trying to quickly get our house on the market since we had a fast timeline on the home we were buying. Tammy was such a facilitator and calm presence in the chaos of trying to get our house ready for market....in a week! She is truly a seasoned realtor with much expertise in the DC market in general and the Sumner/Glen Echo Heights area in particular. She is very committed to her clients and delivering a positive experience. We highly recommend Tammy." - Laura

"Tammy is spectacular. She worked with us for about six months to find our dream home in Maryland, for which we are forever grateful. And she is exactly what you would want in your real estate agent: she's an expert in the business of buying and selling homes, knowledgeable about the real estate market in the DC area, has a keen eye for the value of a home, is a practiced negotiator, and, perhaps most importantly, is eminently patient and understanding. We've recommended her to others, and they have had great experiences working with her as well. If we ever moved again, there's only one person we'd call. " - Antonia

"I bought my house through Tammy, and 15 years later I sold my house through Tammy. In between I referred everybody I knew to her, with great enthusiasm. It’s not just because she is very good at what she does, or because she works incredibly hard – both absolute necessities for the person to whom you are entrusting your largest financial transaction. It’s because she cares. Because she is human. Because she is patient. Tammy is someone whose thoughts and interests are so clearly aligned with yours that it’s like having another member of the working through the sometimes gut-wrenching and exciting moments that are part of most residential real estate transactions. There are plenty of other realtors out there, but I have never met one like Tammy – and frankly, I don’t ever need to. I’m good. " - ID

"Tammy Durbin is an extraordinary Realtor. My wife and I have had the pleasure of working with her on two significant real estate transactions for our . I have no doubt that she will be part of the next one, as well. She has my highest recommendation and stands out in a crowded field as a supreme professional with the right personal relationship skills. " - Phil
