Daniel O'Leary recommends Sean Maley

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!

David D. Barton recommends James W. Argo

Sr. Mortgage Broker Retired

I was a successful mortgage broker for approximately 25 years. Mr. Argo is the most professional loan officer I have ever met. His knowledge and caring for his clients is beyond anyone I have met in our industry.

Jonathan Teel recommends Sean Maley

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!

Thomas Neill recommends Ken Dean

I highly recommend Ken Dean. He made my refinance move smoothly through the process. He was easy to get a hold of and took time to explain the process and answer my question.

Pat Pennington & Jean Schurtz recommend Sean Maley

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.

Cristin H. recommends Aisling Ferguson

Aisling was amazing. I have been in the process of purchasing a home in SF (while being in Europe) and Aisling was a phenomenal support in the process. She has a sense of urgency, is clear in her asks and does whatever it takes to get the job done in a way that makes her clients feel good. Simply put, she was my advocate and I look forward to working with her again in the future.

Celia Velasquez recommends Eric Fairfax

Celia Velasquez

I was in the market of refinancing, and Eric was a reference from one of my best friends whose family has known and worked with Eric for years. So being that she was recommending him? I knew I was in good hands. This was my first time refinancing, and I was very nervous about going through the whole process. From the very beginning, Eric was extremely informative of what the process entailed, and made sure to explain every little detail and step throughout the way. It didn’t matter the time of day... if I had a question about something? Eric was always available. Nothing is more comforting than knowing one can ask a question and request help in understanding the process while being treated with respect. Eric made sure to always explain every detail and process with patience and never in a rush. Every step, he guided me and made sure I truly understood what I was doing and what the expectation was. His communication is key, and Eric made sure to always communicate and keep me in the loop throughout. This made me trust him and felt in good hands throughout. I can not be thankful enough for his work.

Diane Campbell recommends Sean Maley

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!

Tim Dawson recommends Gordon Friedman

SF resident

Gordon is very professional and patient with even the most complicated, yet, small refi. We live in a TIC, which presents its own financing challenges and Gordon knows all of the ins and outs. I highly recommend him as your mortgage and refi expert.

Abby Green recommends Marilee Breslin

I have worked with Marilee for years and continue to do so because I trust her. Her advice and knowledge is solid and she has always been able to secure the best rates for me. She makes the process manageable which is tough to do with the amount of paperwork it takes to refinance...

Adriana Alvarez recommends Veronica Mora

Social worker

If you're looking for an amazing, trustworthy, honest, QUICK, loan officer, VERONICA MORA is the person you need. She's the best out there and is super sweet. Also, she speaks Spanish!

Lindsay Nieri recommends John Joyce

Home Owners

My husband and I recently closed on a 2nd home. John and Asa made it all possible. They were advocates for us; moving things along, crossing the T's and dotting the I's. We are very grateful for their professionalism, responsiveness and overall excellent customer service. They made lifelong clients out of us!
