Sebastien is a phenomenal strategist and a savvy negotiator. In a market as competitive such as the Bay Area, you need someone who is fast and very well-connected. Sebastien managed to draft and submit my offer with speed, and his rapport with other listing agents gave me a distinct advantage. He provided precise input on strategic pricing and potential repair costs, which made me feel confident and informed throughout the entire process. Sebastien is truly a professional who clearly understands how to win in today’s real estate market.

Mareijke helped us sell our family home, which had been in our family for more than 60 years. The house needed quite a bit of preparation; from clearing out decades of belongings to refinishing hardwood floors, painting, and refreshing the garden, Mareijke managed every detail with care and expertise. We could not have successfully navigated this sale without her guidance, professionalism, and experience. She was a wonderful partner throughout the entire process, and we cannot recommend her highly enough.

Always responds to calls and texts within a more than acceptable timeframe. Displays an excellent knowledge of the sales environment and the geographic market . Became a quasi project manager in the process of choosing and interacting with the vendors chosen by us as well as by herself. Adele is a true professional which is an attribute given by us as well as the vendors. The best thing about having chosen Adele is her positive attitude and confidence.

I’m a senior citizen and Heather has helped me on a few transactions. I trust her immensely. Buying and selling is stressful. Heather calm demeanor and responsiveness is appreciated. She’s a great problem solver when and if glitches come up. Her strong integrity is what comes to mind when describing Heathers work ethic. Plus she is just a genuine and kind human being. She was incredibly easy to work with.

This is actually our 4th transaction with Heather. We were able to purchase this condo next door to mine for my senior mother to live in. My mom had to sell her previous residence of 40yrs (less valuable) and Heather represented her in the sale. Mom has now moved to a senior living residence and we just sold the condo (IN FOUR DAYS)! My observation in working with Heather is, she gives the same amount of attention, energy and effort whether it’s a massive Gold Coast Mansion or a smaller cozy Harbor Bay Isle Condo. That is meaningful to us as everyone’s assets vary but Heathers devotion to representing homes and her clients does not. She is who I recommend or refer when anyone’s asks if I know a good Realtor…. Actually, I know a great one!

Working with Sebastien was an outstanding experience from start to finish. He not only guided me expertly through the home-buying process but also showed an incredible knowledge of the local area - city of Alameda 94501 and 94502. He knew the neighborhoods inside and out—school districts, amenities, traffic patterns, future developments, and even subtle differences in community vibes—which helped me make an informed decision beyond just the house itself. His market research was thorough, giving me a clear picture of property values and trends, and his negotiation skills ensured I got the best possible deal. Throughout the process, he made everything smooth and stress-free. He took care of the negotiation part with the seller's agent, and patiently answering my questions and providing guidance every step of the way. Beyond the transaction, he offered valuable referrals and resources for moving in, from reliable contractors to service providers, which made settling into my new home seamless. We are greatful to have him from the beginning to the finish point. Having an agent who combines local expertise, professionalism, and genuine care made all the difference. I highly recommend Sebastien to anyone looking for a knowledgeable, dedicated, and approachable agent who truly looks out for their clients’ best interests.

We had an awesome experience working with Becca to purchase our home in Alameda. Becca is pleasant and patient, and has excellent communication skills. She is very hardworking, responsive, and responsible. She helped us to effectively navigate some tricky situations that came up with the seller during the rent back. She also helped us out with coordinating some work that had to be completed before we moved in. Becca also made our home buying experience extra special with some thoughtful gestures and gifts. We recommend Becca!

If you want a drama-free, home purchase or sale, use Heather Duke's crews. You will not be disappointed.

Highly Recommended Expert in Alameda! ​Working with Sebastien was an outstanding experience. We chose to handle the initial home search ourselves, but his expertise and guidance in the critical stages were absolutely essential. ​Sebastien is a true partner and a total professional. He provided invaluable, precise input on strategic pricing and delivered accurate estimates for potential repair costs, which clarified the long-term value of every home we considered. ​He was always available and incredibly patient with our delays and doubts. Despite any hesitation on our side, he managed to draft and submit every offer extremely fast. ​Perhaps most importantly, he clearly and thoroughly explained every single detail and nuance of the documentation. His attention to detail is remarkable: he even discovered an error in the escrow paperwork that the officer had overlooked. ​We felt completely protected and informed throughout the entire process. If you want an agent who is responsive, patient, and brings a superior level of analytical expertise to your home purchase, we highly recommend Sebastien.

We've worked with Sebastien for over five years, starting as renters and then as buyers in the market for our first home. Sebastien helped us navigate the complicated world of Bay Area real estate and was always a phone call away to answer our (many) questions and provide thoughtful advice. We especially appreciated how he never pressured us into making decisions and always advocated for our interests. His sense of humor and warm personality also helped to make the complicated process of buying a home a lot more enjoyable. After a long journey of tours and offers, we finally purchased a home and are very happy with the outcome. We wholeheartedly recommend Sebastien and he will definitely be our first call if we decide to buy or sell in the future.
