Jorge and Iris made buying my property a smooth and easy experience from start to finish. They were accommodating, communicative, and always prompt in responding to my questions. Both were professional while also being personable and easy to work with. They handled the inspection and negotiations with care, and everything went smoothly without any issues. I’m very happy with the property and would highly recommend Jorge and Iris to anyone looking to buy a home!

Jorge was absolutely wonderful to work with and made our home-buying experience smooth and enjoyable from start to finish. As first-time homebuyers, there was a lot we didn’t know, but Jorge took the time to walk us through every step and explain everything in a way that made the process feel much less overwhelming. He was always patient, approachable, and happy to answer any questions we had. One of the things we appreciated most was how responsive and communicative he was. He was extremely flexible with our schedule and always willing to go the extra mile, even showing us properties at the last minute when we found something we wanted to see. We never felt like we were bothering him or asking too much. Jorge was also incredibly thoughtful and even surprised us with a wonderful gift to celebrate moving into our new home. It was such a kind gesture and a perfect reflection of the care he showed us throughout the process. We’re so grateful to have had Jorge by our side for such an important milestone in our lives. We would happily recommend him to anyone looking for a knowledgeable, supportive, and reliable real estate agent!

Emmanuel was instrumental in helping us achieve an aggressive goal of buying our first home in San Francisco. We had a unique situation, searching for a duplex, and he educated us on the market, the process, and what to expect based on our budget. He also connected us with resources for lending and improvements. He is highly knowledgeable, personable, and connected to the community. I highly recommend working with him and his team.

If you’re interested in buying a home but don’t know where to start, I’d recommend your first step be to contact Hirvin. He set our expectations well from day one so we knew our exact steps to home ownership. He is extremely knowledgeable of the various neighborhoods and genuinely wants to help buyers understand the process. He is also super responsive and answered all our questions thoroughly. We could not have asked for a better realtor to navigate the home buying experience. It’s been an absolute pleasure! We highly recommend Hirvin to anyone looking to buy a home.

Katya was wonderful to work with and was a huge part of making our first home-buying experience such a positive one. She was always responsive, thoughtful, organized, and incredibly supportive whenever we had questions or needed help navigating the process.

We still can’t believe we were able to get the house we had been dreaming of with our very first offer. Katya and Mitch helped us navigate everything thoughtfully and strategically, and we felt confident in the decisions we were making every step of the way.

We also really appreciated how resourceful they were throughout the process. They have an excellent network and were able to connect us with people who made a real difference, including a lender who beat all of the mortgage quotes we had found ourselves. Since closing, they’ve also continued to recommend reliable vendors for everything from painting and electrical work to landscaping and other projects around the house.

One of the things we appreciated most was how personal the experience felt. We never felt like we were just another transaction. Katya genuinely cared about helping us find the right home and making sure we were comfortable throughout the process.

Katya and Mitch make a fantastic team, and their support has continued well beyond closing. We couldn’t be happier with our experience and would absolutely recommend Katya to friends or family looking for a realtor.
