Sergio Sosa is the BEST!

Sergio Sosa has extensive experience in real estate and is completely committed to presenting the home to its best advantage at a reasonable cost. I had no idea how easy he would make the process for me! Sergio knew exactly the changes that needed to be made in the house to catch the buyer's eye. He perfectly balanced work that could be done to show the house with the cost and effectiveness. His market knowledge is exceptional and guided him to making great suggestions all along the process. I loved the changes he suggested, and he worked with great associates to clean, refine the landscaping and stage the home. In addition, the photography was beautiful, head and shoulders above his competitors. He completely understood the legal aspects of the sale, communicated them helpfully and executed them flawlessly. Sergio attends seamlessly to all of the many details of the sale, communicates them effectively and is always a superlative professional! I recommend Sergio Sosa with complete confidence!!

As a first time home buyer, Sergio's expertise and thoroughness was extremely helpful

As a first time home buyer, Sergio's expertise and thoroughness extremely helpful and appreciated. He took the time to explain every step in the process to me to ensure I felt confident jumping into my first home purchase. His negotiations landed me with a solid deal on my first choice home. I highly recommend his services!

Sergio has helped us through two transactions - the purchase of our home in El Sobrante and the sell

Sergio has helped us through two transactions - the purchase of our home in El Sobrante and the selling of our home seven years later. As buyers, Sergio took the time to understand what we were looking for and in a challenging buyers market he was able to advise us on location and offer strategy - ultimately finding us the perfect home. As we planned a move, seven years later, Sergio represented us in the sale of our home. He worked with us to prepare our home for sale and recommended updates to attract as many buyers as possible. He also helped us find vendors for the updates. We were very happy with the sale of our home. If you work with Sergio, expect a tremendous communicator, a level headed and client advocating negotiator, and a fiduciary that will have your best interests in mind at all times. Thank you Sergio for all you have done for our family.

A+ ...... SERIOUSLY

So I wanted to take some time from furiously packing, to write this review and say a public thank you to Sergio. When we started this process as 1st time home buyers, we knew what we wanted, but weren't sure we could afford it. For months Sergio was incredibly patient, he made suggestions along the way about places to look or things we might have to give up to make the dream a reality. But we never felt pushed and always felt that he had time for us and our requests either for disclosure packet, after disclosure packet, after disclosure packet or to see houses often at odd hours because of work and young kids in our house. There was a level of patience and understanding there at all times that made the process, feel a lot better than it probably should have. A month or so ago, we didn't offer on a house and had regrets. We asked Sergio to follow up with the listing agent and Sergio put the deal together through no shortage of persistence and determination. Again, when we ran into issues in what was a very short escrow, he was as calm as possible. No drama, no pressure, just a keen understanding of what we needed to get done and the ability to do just that. I can't recommend him highly enough. If you want a calming presence as part of your home search, while at the same time, a Realtor who is ready to get the deal across the finish line when the time comes, he's an outstanding choice and one of the best choices we made during this entire process.

I recently closed on my first home with Sergio's help and I can't recommend him highly enough!

I recently closed on my first home with Sergio's help and I can't recommend him highly enough. This can be such an intimidating process but Sergio's patience, honesty, and attention to detail made it easier. No text or email ever went unanswered, and he went above and beyond smoothing out the inevitable speed bumps, even those that popped up at the end of the day (which they always seemed to do). Sergio pulled dozens and dozens of disclosures and wrote at least ten offers for me in 6+ months; and even though I was using a few different first time homebuyer programs that required probably more paperwork than the average offer, his enthusiasm and quality of follow-up never flagged. I'm so grateful for his time and support, and recommend him to anyone looking for someone to have in their corner as they navigate the Bay Area housing market. Thank you, Sergio!
