While we were looking for a house, Aqsa helped us tremendously. You can immediately tell shes someone who genuinely loves what she does, her passion, patience, and care really shine through in every interaction. Even though we ultimately purchased our home through a family connection, Aqsa was always on my speed dial. She guided us through the entire process, from sharing honest opinions about different homes to offering thoughtful insights during showings, and even helping us think through contract details and next steps. No matter how small the question, she was always there with clear, practical advice. What really stood out was her experience and sharp eye for detail. She would notice little things others might overlook and explain what they could mean long-term, helping us feel informed and confident at every stage. Having her perspective made a huge difference and brought so much peace of mind. We truly cannot thank her enough for the generosity, time, and support she gave us throughout the journey. She is not only an amazing realtor but also a genuinely wonderful friend. I look forward to working with her whenever I can in the future, and I wouldnt be surprised at all to see Aksa running her own brokerage one day, she absolutely has the vision and dedication for it. Wishing her continued success aEUR" anyone would be lucky to have Aqsa by their side in their real estate journey.

Arevik Tigranyan helped us buy our first home in the Bay Area with minimal stress. From the beginning, she was kind, honest, and patient. She never pushed us to close or made us feel pressured to rush or buy the first house we sawaEUR"instead, she made sure we felt confident and informed at every step. Arevik is also an excellent resource. She knows the area very well and helped match us with what we needed, such as a good school district and a nice neighborhood. She connected us with great vendors and helped us understand what work a house might need. Her assessments and cost estimates were pretty accurate, which made the process much less stressful. Were very satisfied with our experience and would happily recommend Arevik to anyone looking for a trustworthy, knowledgeable, and supportive realtor.

If you are buying a house for the first time and not really familiar with the process, the person who can help you the most and guide you in the right direction is definitely Sara. She is absolutely an expert in her field. She definitely plans everything on time and keeps you informed and updated. She also has an excellent team that she works with. We think we got a great house at a good price Thanks so much and appreciate you.

We recently had the pleasure of working with Arevik Tigranyan to buy our home in Sunnyvale, and we cannot recommend her highly enough. The Sunnyvale housing market can be incredibly aggressive, with most homes receiving multiple competing offers. Arevik fought really hard for us in that fierce competition. The most amazing thing is that this was the first and only house we put an offer on, and we won it! From start to finish, Arevik was supportive, genuine, and extremely responsible. What sets her apart is her incredible depth of knowledge in every aspect of real estate from understanding the nuances of the location and home conditions to navigating inspections. She is truly honest and looks out for your best interests. She will frankly tell you if a house has issues or isnt a good investment, rather than just trying to close a deal. Thanks to her diligent work, we closed on our home in less than three weeks. If you want someone who genuinely cares, will only recommend the best homes, and can help you win in a competitive market, hire Arevik.

Corinne was an amazing buyers agent, especially for me as a first-time home buyer. She was incredibly responsive and always quick to answer questions, which made the entire process feel much less overwhelming. I really appreciated the welcome packet she provided, it clearly broke down each step of the home buying process and helped me understand what to expect along the way. Corinne also did a great job negotiating the home price on my behalf. She is excellent at keeping the ball rolling and making sure all parties stay on track, which ultimately helped get us to closing on time.
