Karan Ramchandani recommends Sean Maley


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!

Michelle Murre recommends Sean Maley

Founder, Azurine Travel

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!

Vanessa Lemaire recommends Sean Maley

Film Producer/Director

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.

Meagan Gazzoli recommends Sean Maley

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.

Brigitte Brady-Harris recommends Sean Maley

VP, Marketing

This was our first time working with Sean. He is a terrific broker who helped us secure the perfect loan to purchase our dream home. He is confident, experienced, friendly and incredibly responsive. He was available whenever I reached out and communicated flawlessly across all parties involved in the purchase. Sean's great relationship with his peers made the process so smooth. We can't thank Sean and his team enough for top tier service and results!

Nate Padavick recommends Sean Maley

Illustrator & Graphic Designer

From the very start of the loan process Sean was very helpful and unbelievably responsive. He really went out of his way on several occasions: working late on a Friday to push through paperwork, meeting us on a Sunday to obtain a signature, and replying to emails within minutes. Oh, and he found us a great loan too! It was a pleasure to work with Sean and I've already referred him to several friends.

Susan Landwirth recommends Sean Maley

Sean was so efficient and so independent. He asked me for so little once my papers were submitted. I can't recommend him enough. He's the best loan broker I've used in 40 tears of buying and selling real estate.

Sasha Amiri recommends Sean Maley

Admin Coordinator/Business Services

We got introduced to Sean by an agent we were using and when we explained to him the emergency situation we were in, he did not hesitate to jump in and help. Even when we switched agents, Sean was always watching our backs and keeping us in the loop. We had 30 days to find a house and close and we did exactly that. Once we found the house we wanted, Sean and his team did everything they could to get us to close right before the 1st of the month. He was always honest and forthcoming and we never questioned anything he asked of us, because he would explain everything in detail and made sure we understood it. He always kept us updated along the process as well. I would recommend Sean in a heart beat to anyone I know that is interested in purchasing a house.

Kristina Beste recommends Sean Maley


I have had the opportunity to work with Sean twice refinancing my home. I can not begin to say enough amazing things about him! I have never worked with someone SO efficient and competent in my life. He was referred to me from my realtor step mother who has said time and time again, that he is her favorite Loan Advisor to work with. I have heard so many horror stories, of loans and refis taking months and months. We closed in RECORD times and he made it feel like such a breeze. I am one that gets intimidated with paperwork and he guided me every step of the way. I will recommend him to everyone I know. Both times he always seems to work magic and get me the best rates possible. He has a natural instinct for the business and it feels like your best friend has your BACK! Which seems like a rarity know days....I am blessed to have connected with him. Also he is a BLAST to work with! His good energy surrounds you!!!! Thank You Sean for guiding me in these big steps in my life! I also have never met anyone so dependable or prompt in the business world.....THANKS AGAIN SEAN, YOU ARE TRULY A GIFT!
