Jim and his team have extensive experience working with Bay Area homebuyers and have never hesitated to provide additional clarifications and guidance through the process. Jim is not only knowledgeable and efficient, he is always prepared- there are always Plans A and B available to ensure that we have the best chance of closing. As a first time homebuyer, I could not recommend Jim more as a broker who will get the deal done!

I cannot recommend Bob highly enough! As a first-time homebuyer, I was incredibly nervous about the mortgage process, but Bob made it smooth and stress-free. He was always available to answer my countless questions, responding to my emails promptly, even on weekends and late at night. His patience and dedication were truly remarkable. Bob didn't just process my loan; he genuinely guided me through the entire homebuying journey. He provided invaluable advice on when to lock in my rate, and even proactively alerted me to favorable market changes, helping me secure a fantastic rate. He was also incredibly efficient, working tirelessly to expedite the process without sacrificing any attention to detail. If you're looking for a knowledgeable, responsive, and genuinely caring mortgage lender, Bob is the person to call. He exceeded all my expectations, and I'm so grateful for his support.
Sean was friendly, efficient, skilled, concise and met every deadline while ensuring all involved in the process did as well. He also has a fun sense of humor which helped navigate my 1st home purchase/loan. He and his partner David work seemlessly! Highly recommend them!

I had a great experience with Bob. He is very responsive to any questions that came up along the way, even as I considered other lenders. Bob ended up taking over my loan and was patient as I navigated some frustrating complications with another lender. As delays occurred, I was worried it would take too long to close, but he was able to work through unexpected changes and quick turnover times.

Orlando and his team are, truly, miracle workers. He worked with our complex self-employment income, got us fully qualified in record time, and got us closed in less than two weeks. We got our dream home because he was so through, responsive, and quick. As long as you stay organized and can match his pace, Orlando really makes the process a breeze. I would particularly recommend working with him if you are self-employed or are having a hard time getting other lenders qualify your income.

An impossible thing finally became a possible thing like our dream comes true so quickly with Annie unbelievable help and assistance. After a few difficult periods, we closed our new single family house recently. We cannot use language expressing how much we appreciate Annie’s efforts for our closing new home after we got mortgage loan. If you are looking for a new house and through an approval of a bank property loan, please find Annie who is a right person perfectly to do it.

I have had the pleasure of working with Pov Oum for nearly seven years, during which she has consistently exceeded my expectations with her exceptional service. Pov has a remarkable ability to assess market conditions, weigh the pros and cons related to my goals, and connect me with relevant contacts for day-to-day execution, whether for my corporation, personal finances, or various aspects of my life.
What began as a professional relationship has blossomed into a strong friendship. In our most recent transaction, Pov assisted me in executing a HELOAN and purchasing two condominiums for investment purposes. Throughout the process, she took the time to clarify my expectations and was always available—day or night—to answer questions or provide status updates, especially in the final stages. Her commitment made me feel valued; she dedicated countless hours to keep me informed, fully aware of my timeline and objectives. I was particularly impressed by her deep understanding of my profile and her ability to communicate effectively with investors. In this transaction, some investors struggled to grasp fundamental aspects of my profile, but I knew I could rely on Pov to clarify these points and help facilitate the approval process.
To Pov, I want to say: keep up the outstanding work! My family greatly appreciates your dedication to our financial well-being and your guidance on every transaction, whether it involves moving forward or waiting. You’ve showed your care for us goes beyond any incentive linked to the transaction. Your management and support were invaluable, especially in addressing the builder's concerns during the home purchase process.
Thank you,
Neeraj

I was moving from the Midwest to the Northern California Coast. I needed a trusted advisor for more than a loan. I needed confirmation I was making a solid financial decision. James Argo, took the time to get to know my motivation. He advised me.in the very same way the sun—whether or not it is recognized, appreciated, or even seen—is accessible to whomever might benefit from it. I found James Argo to demonstrate incredible integrity in giving clear and honest guidance, without a strategy, without a plan, and without ambition. This quality is a rare commodity and very much needed in the world. I am beyond delighted in my new home with amazing opportunities blossoming at every turn. Opportunities for growth are built on a solid foundation. I’m delighted with the entire team experience and the how quickly the services were presented and provided. Consider yourself fortunate to have the opportunity to work with James and his team.
