I highly recommend Sean and his team. He help me secure financing to buy my partner out of our home during our divorce. I had so much going on and honestly numbers and paperwork are not in my wheel house, but Sean helped every step of the way. He was so efficient and knowledgeable, making a difficult situation as easy as possible.

I cannot say enough wonderful things about Sean and his team. As first time home buyers, my husband and I had many questions and needed lots of hand holding throughout the loan approval and escrow process. Sean was always available, patient, and enthusiastic about taking our phone calls and emails. He made us feel comfortable and well taken care of during a very daunting time in our lives as first time buyers. It was an absolute pleasure working with Sean and I'm so glad we were introduced to him.

I would highly recommend Sean. He made this process for us as easy as possible. Being Latinos and first time buyers, it was intimidating to trust anyone with such a huge purchase. Sean was highly recommended to us and I am very happy we chose him.

Sean was diligent and kept our loan moving forward, we ended up closing much earlier than we thought possible.

Sean was awesome! With his assurances, we were able to make a contingency-free offer with a relatively short close time, which made our offer stand out to the sellers. During closing we were struggling to get insurance quotes - sean came through again, connecting us to a reliable agent and working with him to get us coverage in time. Thanks Sean!

Working with Sean was a great experience and he and his colleagues are the best. Our real estate agent referred Sean to us and we couldn't be happier. Sean found us a loan program that worked for our circumstances. and was an absolute joy to work with . From application to closing, Sean was very professional, courteous, and helpful in every respect. Do yourself a favor and give Sean a call next time your looking to finance your real estate purchase, or refinance and existing property. You won't be sorry.

We would not be in our home, which we bought five years ago, without Sean and his team. And we just completed a re-fi with them. Both times were incredibly smooth even for a purchase that wasn’t typical. Sean is very responsive which makes communication efficient. We also appreciated his advice to wait on a re-fi until the timing made sense. Highly recommend!

Sean helped us get our second home. He is the most amazing broker we ever met. Sean was able to help us to get the finance based on what we can without us selling our current house. He response to all our questions instantly. When we got our second house offer accepted, there was a major issue with the new house that could potentially delay our closing date. Sean worked tirelessly to help us get the house close on time and eased all our concerns and stress. Sean is incredible responsive, super professional and easy to work with, and we feel like he is always on our side. We feel so grateful to be able to work with him.

We worked with Sean and his team to finance a seasonal home, and I think they are the only reason we successfully closed on time! Sean is an experienced pro who asked all the right questions, worked extremely quickly at each step of the process, and helped get us over the finish line when we hit some last minute snags before closing. Thank you Sean for your excellent service!

I recently closed on a home and Sean worked tirelessly - from the start - to make it happen (after another loan advisor wasn't able to). He was able to secure an incredible rate and he felt like like an advocate for us throughout the process. He is very detail oriented, thorough, and remained accessible for all questions. I would strongly recommend Sean!

Having known Sean and referred him over the years, It was nice to actually use him personally.
Actually, Sean called me and said" Boy have I got a program for you!"
He worked his magic, and the whole process was painless.
Loved working with Sean and David!
