Sebastien was responsive to our needs and hyper communicative. Even on vacation he was reachable and plugged in. Sebastien was thorough. He showed up at every house we showed interest in and inspected it until he was satisfied that he'd be able to answer any questions we'd have and until he had every question of his addressed. Sebastien was also very knowledgeable. He asked the right questions to the sellers, dug into details about each property, and had deep market knowledge to integrate into our understanding about each property. Finally, Sebastien builds relationships. He connected with sellers' agents and built tremendous rapport with them each time we submitted an offer.

We were first-time buyers on a property that came with some real complexity, and Sebastien was key to making it all work. He handled everything with confidence and calm, knew what mattered, knew what didn't, and never made us feel like we were in over our heads. When we came up against multiple offers and weren't sure we'd come out on top, his strategic approach to the terms — not just the price — ended up making the difference. His charm and ability to put everyone at ease went a long way too. Throughout the whole process he was warm, knowledgeable, and genuinely available whenever we needed him, which as first-time buyers was often. He was the steady hand that kept everything moving. We trusted his read on the market, we trusted his instincts, and he delivered. Would absolutely work with Sebastien again.

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.

Sebastian was excellent in getting us up to speed to buy our first home. He found the perfect house for us early in our search and helped us negotiatiate a great deal and fast closing. I would recommend him to anyone.

As a person that purchased a home on their own, Sebastian made the process easy, clear and stress free. From the day I met him during the house tour to the day I closed, the experience was easier than I could have ever imagined. He made himself available to take my calls/texts at all hours of the day, had numbers to contractors in almost all fields and also continued to check up on me even after I was moved in. As someone who has friends that are realtors, I would still to this day continue to go with Sebastien.

He was with me the whole time way with positivity & exuberance. His demeanor was always upbeat. He hails from a small coastal town in Brittainy, France-which I had the rare chance to visit on a day trip when I was married ( my ex is from Jersey, Channel Islands).

* Responsive and flexible. * Domain expertise with income properties. * Principled position on risk based decision making. I was upfront with Sebastien that identifying a "perfect" property was an ambiguous challenge. He supported a multi-month exploration of the marketplace where we reviewed properties ranging from condos to SFHs to small commercial apartment buildings (5+ units). In the end we were able to bridge my absolute requirement to provide housing for adult children while mitigating run-rate risk with additional rental income potential.

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.

I was recommended Sebastien from a friend who recently bought their home with his help, and I couldn’t be happier with his results. Sebastien was extremely attentive to what I was looking for in a home and helped me tour several candidates. He was a huge help in assessing the older homes we looked at, making sure to look at the electric for any evidence of knob and tube and examining the foundations to ensure safety and accuracy of the list price. We lost out on a couple of homes initially due to high interest, but Sebastien was friendly with every listing agent and had them rooting for our success. And when we finally landed on a home we were willing to fight for, Sebastien made sure our initial offer was competitive and kept in close contact with the listing agent to ensure we could meet any counter bid without going over our budget. Sebastien is an incredible thorough agent, and you can really tell he cares about his clients and makes sure that they find the home they truly love. Would highly recommend him.

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.

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.

I highly recommend Sebastien Colas as a real estate agent. He did a phenomenal job made my home buying experience enjoyable. He truly understands the market and is a very savvy negotiator. His skills greatly exceeded my expectations. I couldn’t be happier with the outcome.
