Alan,
You never cease to amaze!
Words can not describe the pure elation and gratitude you have helped create for me and my family for the most successful commercial funding loan close of my long career. My new 15k sqft commercial office bldg to condo conversion opportunity transaction represents our dream development opportunity in the A+ location Encinitas Ca 2.5 blocks to Moonlight Beach. The barriers to entry here are extremely high, so when the opportunity arose to purchase, it wouldnt have happened without the critical funding for the deal which you secured.
Mind you, this was no ordinary deal. The initial bridge financing was specifically challenging given the current adverse office environment which is still depressed albeit in recovery mode. Finding a needle in the haystack or rather the perfect lender to fit the bill was no easy challenge. Securing the perfect lender is such a critical aspect of your expertise in being able to match the deal with the right lender who not only believes in the vision but truly wants to be a partner in the success of the project.
Shout out to C3 bank and their entire underwriting team for a magnificent job executing to close.
There are so many forward strategic planning factors and stages to consider in a deal like this from acquisition, to short term office lease up, to construction, to permanent financing when fully leased. Alan excels in understanding the progression of the deal flow and insuring the momentum and progress will continue and not succumb to stagnation due to future global underwriting issues not considered ahead of time.
Commercial lending inherently posseses a myriad of underwriting challenges that are well above and beyond securing residential financing.
I simply would not have been able to navigate and close the single most mportant commercial financing loan of my life without you and your skills that go above and beyond residential financing
I happily endorse you to all for any and all commercial financing needs.
Sincerely, Jason Smith

POV is excellent on her job, she helped us a lot with our loan and guided us through it. Very good in dealing with client, communicates well by answering back our inquiries right away. Very pleasant to talk with . I would recommend her if given the chance, her and our agent Christy Pak coz they work well together.

Sean closed a loan in 21 days start to completion for a somewhat difficult second home property. He had great resources at his fingertips, was communicative and an overall consummate professional. He appeared to work at any hour of the day or night something needed to be done. As one in a service industry, this was incredible. I suppose the best thing I can say is that I was so happy with what he did with this mortgage, I have him working on refinancing on another property.

Orlando did a fantastic job securing a mortgage for my husband and I shopping for our first home. My husband is a solo investor, so his income is super complicated, and Orlando was able to shepherd us through the process and get us the loan we needed with a competitive rate. He was kind, empathetic, and super communicative. We would love to work with Orlando again one day and highly recommend him!

We appreciated his honesty and forthrightness, his availability and fast responses, and his ability to explain everything we needed to know about rates and points and closing costs in a way that didn’t make my eyes cross. His secure document upload site was easy to use. We had a short closing window and he managed to get everything lined up for us in plenty of time. Thanks Joel! We will recommend you to all our friends and family!

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!
