    Lender Review

    I had a fantastic experience working with TAG Real Estate Team (The Arsondi Group). From start to finish, their professionalism, expertise, and commitment to excellence truly stood out. The team was responsive, knowledgeable about the market, and proactive in guiding me through every step of the process. Their clear communication and attention to detail made everything smooth and stress-free. It was clear they genuinely care about their clients and work hard to achieve the best possible results. If you’re looking for a dedicated, trustworthy, and results-driven real estate team, I highly recommend TAG Real Estate Team (The Arsondi Group). Five stars without hesitation!

    Client Review – Tony Arsondi

    All 5 Stars! I challenged Aaron and the TAG team to achieve the highest sale in my neighborhood’s history—and they did it! Aaron’s positivity, professionalism, and constant availability were unmatched. My home had an incredible location and yard, but less-than-ideal square footage. Still, Aaron, Tony, and TAG understood its true value and found the right buyer who appreciated its uniqueness. Their expert marketing, showing strategy, and guidance made all the difference. I wouldn’t hesitate to work with Aaron, Tony, and the TAG Real Estate team again!

    San Jose Seller

    Tony, Elana, and the TAG Real Estate Team sold our home, and we only wish we had hired them from the beginning! From the moment we made the switch, we knew we were in good hands. A marketing machine for our property. From the very start, they proved to be trustworthy and strategic, providing a detailed pricing analysis and a comprehensive review of comparable properties. Their deep connections across the entire SF Bay Area were invaluable. The team is caring, committed, and always working tirelessly for their clients. They consistently went the extra mile. Thoughtful, available, and truly dedicated—thank you, Tony, Elana, and the entire TAG Team!

    Carrie & John – Sold Their Home in Livermore

    Tony and his team were wonderful to work with. We sold and bought a new home with him. His team is very professional, knowledgeable, and trustworthy. They also have lots of connections with other realtors and lenders, which helped us get a house off-market! Highly recommend working with Tony and his team.

Tony is transparent and honest, a skilled negotiator, understands the importance of marketing, and you can tell the guy just really loves his job! Thank you all for an excellent experience with both buying and selling!

    Brookelynn & Brandon – Bought and Sold a home in Livermore

    My husband and I came to Tony with quite a laundry list of must-haves for our first home; move-in ready, lots of space, tight budget and to be moved in before my vastly approaching due date. Yeah, we were THAT first time home buying couple. He took on the daunting task head-on and worked tirelessly to find us just the right house. He was very communicative throughout the entire searching and purchasing processes and was able to get us into a beautiful home quicker than expected. We couldn't be happier with the house and location and highly recommend The Arsondi Group for their real estate expertise!

    Clifford family- Bought a Home in Mountain House, CA

    I would highly recommend Tony Arsondi (Arsondi Group/Keller Williams) to anybody looking for a realtor! From the moment I contacted Tony with interest in buying a home, he went to work immediately to help my wife and I find the home we wanted. Luckily for us and because of the work Tony assisted us with we were able to close on the home we wanted within one month of starting our search! Tony is very professional and informative on the entire process which allowed us to get the house we wanted. He has spent a lot of time with us on the phone answering our questions, meeting us at the property and communicating with the other realtors/sellers involved to make sure we were informed and comfortable with our decision. Tony made it clear from the beginning that he wanted to make sure that we got the house WE wanted and made sure we didn’t feel any pressure of buying a home we didn’t feel comfortable with. Now we have a gorgeous home that we will be starting our family in! I would refer him to any of my friends and family! THANK YOU TONY!!
