We had a great experience working with Sean and Guarantee Mortgage. When I had questions, they were quick with a reply and patient in explaining things I didn't know about. As someone new to the home buying process, they made what could have been a painstaking process into a simple, direct and straightforward path to our new home. We couldn't have been happier with their work. It was a positive experience and I would highly recommend Sean and his team. Bravo!

I am blown away at the diligence, focus and personal touch I got from working with Sean and Guarantee Mortgage. We started the process for the mortgage and, in just a month, closed on our new home. I cannot thank them enough for getting things done so quickly and with such care. Interestingly, I was with my realtor and he told me that typically getting across the line with other brokers has been a struggle, but with Sean on top of everything, we came in one week early. If that is not service, I don't know what is!

Seamless and flawless.... Sean is the best! He's helped us through several transactions and all have been positive experiences, with this latest one being exceptionally easy and stress-free. He is professional and incredibly responsive.

We've been working with Sean since 2004 and have always been super impressed by his professionalism, speed, and immediate response to our (many) questions. We've done numerous re-fi's over the years with Sean exclusively but what originally sold us on Sean was back in 2004 when he rescued us from a horrible situation with a disreputable mortgage broker. Sean steeped in and saved the day by securing us a loan in record time. We're still in the same house today thanks in large part because of Sean's actions almost 15 years ago. Highly recommend!

Sean is wonderful! He has guided us through several transactions and every time the experience has been positive, professional, and dare I say easy. He is fun to work with and extremely knowledgeable. He is very responsive to phone calls, text messages, and emails and his attention to detail is amazing! We wouldn't do a mortgage transaction without him!

Sean is amazing! I've worked with Sean over the last 2 months to get a loan for a 2 bedroom condo, my first purchase, in SF. He helped us along every step of the way, patiently explaining and re-explaining each of the mind-bogglingly complicated steps in the process of getting a mortgage loan.

Sean is the BEST communicator I know. Nearly every time I called him over 2 months, he either answered immediately or called me back within 1 hour. His email response times were phenomenal. He is personable, easy going, competent, and follows through on every request.

Pick him.

Sean consistently offered support through our new home purchase. He was accessible and always prepared for our (numerous) questions.

I appreciate his follow through and his attention to detail made the home purchase process fairly simple to navigate.

My highest recommendation for Sean!
