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!

Efficient, knowledgeable and has 100% follow up. Sean hits the trifecta of borrower needs. The team is great too, wish I had staff like that. He never gets flustered, he just solves issues and keeps you moving forward. Thank You Sean.

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!

Sean helped with our initial loan and refinance. The whole process was very fast and professional both times, with plenty of guidance for the steps we needed to take each time.

I have know and worked with Sean for two years. He worked tirelessly for us and provided exceptional service that was matched only by his knowledge and ability to navigate through the daunting process of obtaining and refinancing mortgages. Highly, highly recommend!

Working with Sean and his team has been incredible. It was our first time getting a mortgage and Sean walked me through step by step, advising and explaining all as we went. He got us an excellent rate and I look forward to working with him for years should we need to refinance or purchase a second home. Even our title company in Napa called Sean a 'dynamo' and said he was one of the most proactive and detailed mortgage brokers they've ever worked with. I cannot recommend Sean more highly!

With all our write offs on our tax returns, our income was low, yet Sean helped us afford a competitive amount and got us a great interest rate. We stood no chance seeking property in Mill Valley. Not only did Sean make it feasible, we succeeded on our second bid! Sean got us through the closing process with speedy responses to all our emails, guided us with the unfamiliar terms and numbers and helped us close in 20 days! It has been a real pleasure buying our first property with Sean. I can't recommend him enough.

I have known Sean and David for many,many years. They are professional, they give their clients their full attention, they work very hard and they get their deals closed. Most importantly, they are honest, They always answer their phone and promptly reply to emails. They genuinely care about each and every person they work with. I more than highly recommend them.
