Josh was fantastic to work with! We had a very difficult property to sell and he advised us over several months and guided us every step of the way, helping us to complete the sale efficiently and maximize our returns. I can highly recommend Josh for all your Napa real estate needs!

Josh has helped us buy and sell. We sold when interest rates were high yet got well above asking. I accredit this to our finishes AND the outstanding marketing his team put together. The advertising pictures and 3D tour far exceeded anything I've ever seen. Thank you Josh, Rysn & Jennifer.

Josh was my realtor when I bought my home and sold it 5 1/2 years later. He knows Napa Valley extremely well being a native and is so professional. I couldn’t have asked for a better agent, he’s the best!

Josh & his partner Ryan were excellent in every way during not one, but both of our transactions. Josh & Ryan handled the issues with the buyer of our property with flawless expertise and honesty. Never during the process did I feel out of the loop because their communication skills are phenomenal. The sale of our condo ultimately was extremely smooth & because of their great communication and networking skills, they were able to find us a house that was perfect for us to purchase before going back on market. I would highly recommend using this team.

This is the first time we have ever sold a home and we were nervous and unsure of the process, especially during these times of COVID. Josh and his team explained the process clearly and worked fast to sell our home. Within 6 days, we had a few offers on the table! Josh is always a pleasure to work with. Nothing is too big or too small for him and his team. Josh is very responsive and follows through on everything. We are extremely happy with the results we received and just how easy this process can be when you work with the right people. We feel like we have developed a lasting relationship with Josh and will continue to utilize him and his awesome skills for all of our future real-estate needs! Thanks again, Josh!

Josh is extremely patient and diligent! I would never work with any other realtor. As first home buyers, we had a million questions and he was always a text or a phone call away with a detailed answer. I couldn't have imagined the process without him by our side. He's an expert negotiator with your best interests in mind. I'd highly recommend Josh!

I would more than recommend Josh as your realtor, but as a must.Our family circumstances were challenging and Josh met them head-on.My husband and I have had the occassion to deal with many realtors,and it would have been such a pleasure to have had Josh there. Our circumstances made it very difficult to be there for so much of the sale and Josh removed so much of the stress. For example, he put out the trash for us, he worked with our neighbor to coordinate access to ithe house. His recommendations saved us so much turmoil His presents on site was soooo appreciated. Josh is a winner and I would say... go with JOSH Kaaren Guenther

I am very pleased with my recent purchase with Josh. Through some complications with the HOA, the deal drug out for nearly 3 months. Josh remained focused and helped push things forward. His business skills combined with his vast knowledge as a Napa local proved invaluable in my process. Highly recommended!

Helped me buy home • 2019

Choosing Josh Diaz to represent us when purchasing our first home was hands down one of the best decisions we made. Josh made what we thought was going to be an incredibly stressful experience as smooth as possible, especially considering we didn't know anything about the process. He is incredibly knowledgable in all areas of real estate, was available to us whenever we had questions or wanted to see a listing, and was just an absolute pleasure to be around. Josh was so on top of it during negotiations with the seller and really helped us feel confident during the whole closing process. We are now in the home of our dreams and are so thankful to Josh for all of his help! Highly recommend!
