David Brant recommends Kathy Derangi

As first-time homebuyers, Kathy was an exceptional mortgage broker for us. She laid out a very clear financing path for us given our budget and down payment, and she was transparent with us on what we would get approved for. Kathy was on top of everything when it came to loan pre-approval, and more importantly the very tight Close of Escrow period. My fiancé and I highly recommend Kathy for any first-time homebuyers in the SF market.

She's the best - very clear, very concise, very friendly and very helpful. Made the mortgage process as smooth as possible and was flexible when I had a funding hiccup along the way.

Chris recommends Larry Horowitz

08/01/2018 Larry is professional, reliable and went to great lengths to make our loan process run smoothly. He is very attentive to detail, and quickly responded to phone calls and emails. He went out of his way to communicate with our realtor, escrow officer and even the seller when questions needed answering. We have used Larry for multiple real estate transactions and highly recommend his services.

Carl recommends Larry Horowitz

08/01/2018 I've been working with Larry for over 25 years now, and he has always been helpful and reliable. He went above and beyond the call of duty for this recent transaction. He was creative, patient, and persistent. Not many lenders could have helped me in the way Larry did.

Michelle W recommends Aisling Ferguson

As a first time home buyer in the bay area, Aisling made the loan process incredibly easy and painless for me. I have nothing but good things to say about the way she works and her ability to make things happen in a timely and efficient manner. She was highly communicative every step of the way, and I never had to followup with her as she was always following up with me. While extremely busy, she also never failed to leave time for me and reminded me to reach out with questions or concerns even on weekends. I fully endorse working with Aisling and look forward to doing so again in the future.

Cy Berlowitz recommends Aisling Ferguson

"Aisling Ferguson assisted us in obtaining two loans to help us purchase a condo for our daughter in San Francisco. It was a complicated transaction but Aisling sailed through it like like the consumate professional that she is. Besides, she held our hands all the way through the transactions.until its completion. Our daughter is now the proud owner of a San Francisco condo, and we couldn't be happier. Anyone needing assistance with a loan would be fortunate to use Aisling Ferguson.

Sincerely Yours,

Orlando did an excellent job, and worked through challenges faced by retired clients. He responded to my questions even when he was out of town. I felt confident and reassured throughout the process and I strongly recommend him to family and friends.

Surinder Bains recommends Phil Caulfield

Senior Innovation Portfolio Project Manager

Phil's transparency throughout the process made our refinance outcome very productive and efficient especially since both my husband and I work long hours. He made sure he explained all the details that matched up to our needs so we qualified for the best rates under our circumstances. He also patiently guided us on the documentation and never once over-promised on any rates he could not deliver. I am very pleased with the rates on the refinance and has given both my husband and I peace of mind back after years of worry if we could get even qualify for a refinance, let alone get a great loan that Phil was able to secure for our home! Thank you Phil for your support!!

My husband and I are beyond happy to have worked with Aisling during our house hunting journey. She's incredibly knowledgeable, responsive and a fantastic problem solver. When there were hiccups along the way, Aisling presented us solutions and help guide us to make informed decisions. We got pre-approved and closed on our house within 8 weeks which to me and my husband, is wildly fast since we are first time homeowners.
