Katy Reichmuth recommends James W. Argo

CEO of The Simplified Life

James helped me through a refinancing of my rental property in San Luis Obispo. I couldn't have been more pleased with his thoroughness and likability, as well as the way explained each step of the process so that I could understand it. While refis aren't exactly fun, this was as painless as possible. I couldn't recommend him more.

Patricia Assani recommends James W. Argo

Jim came highly recommended and did not disappoint; what a pleasure to work with him! He was relentless at finding the best loan for us, while kindly appeasing our first-time home buyers' doubts and responding to our many questions. His knowledge, expertise, and patience, thoroughly prepared us for each steps of the loan process. I would seek his services again without a minute of hesitation.

Sebastian Alioto recommends James W. Argo

VP Finance

Jim is not only thorough and timely in processing a loan application, but he offers insight and solutions on how to best go about solving difficult problems. Over the last ten years when considering a new loan or a refinance, I knew the best first step was to call Jim for his view and perspective on the availability of funds as well as the steps needed to improve my situation.

I therefore highly recommend Jim as a resource and a proven professional.

Carol Fuerth recommends Orlando Diaz

School Librarian

Orlando was wonderful to work with during my home refinance. He was easy to communicate with and always kept me informed during the whole process. I felt I received a great interest rate and am very pleased with how quickly we were able to complete the process. When there were some hurdles, Orlando smoothed over the bumps. I would definitely recommend Orlando Diaz!

Micaela gonzalez recommends Orlando Diaz

Orlando Diaz was very professional representing us and goes the extra mile to reach the attainable goal in our best interest. He was consistent would follow through to answer any questions, concerns we may have had. Our situation was a challenging one and the bank we were working with presented us with special criteria to close our loan. He keeps the clients goals and best interest in mind. A big thank you for a job well done even with all the challenges we met.

Jim Argo helped me with a refinance recently and as a result I’m saving money which I’m very happy about.

Patrick Fitzgerald recommends Kathy Derangi

Social Worker Supervisor

Kathy did a fantastic job for me when I bought my first home on my own after my divorce. She was willing to answer the endless stream of questions I had for her throughout the process in a way that was informative and minimized my anxiety. I was able to joke with her and have fun even when things felt overwhelming and I really appreciated that the most!

Scott Shell recommends Aisling Ferguson

Aisling help us refinance at a 15 year fixed rate that was significantly lower than our adjustable rate mortgage. Paying if off at a lower rate and in fewer years, two wins! Many thanks Aisling for your assistance.

Self

Aisling is the best of the best. My situation was very, very, very complicated and untraditional, and she guided me with care, confidence and total integrity every single step of the way. And she got me an amazing loan. I could not recommend her any more highly.

monica santiago recommends Orlando Diaz

client

Orlando did a great job closing on our property in a short period of time! He was very eager and professional, answered all questions we had and was available whenever we had questions or needed to discuss something with him. Our situation was a bit out of the norm as we were not always available to read emails, sign, speak on the phone and other things people with a 9-5 job can accomplish. He made himself available to us and was very patient. I would definitely recommend Orlando to work with to friends and colleagues.

Argo and team locked in a preferred interest rate, guided us through the the complex mortgage process, warned us of potholes ahead, and executed successfully in record time.

David Fowler and Clementine Suiffet recommend Kathy Derangi

Business Owner

If there were six stars we'd give them. Kathy was so detail minded and so on top of our transaction we completely forgot she worked for a mortgage company. Never had anyone in her industry make the process go so smooth before.
