John and Jason recommend Sean Maley

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!

Cristi Iannuzzi recommends Aisling Ferguson

There aren’t enough stars to thank Aisling for always giving us 100%. I’ve lost count of the number of loans/refinances she has done for us now and I’m amazed by her ethic and hard work. Thanks to Aisling that we always get the best deal that can be done.

Jeffrey Smith recommends Aisling Ferguson

Registered Nurse

Aisling is a professional in every sense. She was on top of our documentation at all times, and kept us fully informed every step of the way with flawless communication. She assisted me with a property purchase more than 15 years ago, and I was thrilled to be able to work with her again for this most recent purchase. I can't recommend her highly enough!

Robert A Horton recommends Orlando Diaz

co-founder of untraining

Orlando went beyond the call of duty for us as buyers of our home, where we had rented for 30 years. He helped us through sticky situations and crisis. He was friendly helpful and available. I can not say enough positive about him as this was a difficult passage for us and he helped us get through it.

I highly recommend Alan!!!
He is an expert loan broker & very professional. He helped me buy my first home and now made my first refi easy. His Customer Service is excellent and he is always available to answer ALL MY questions.

Kiki Poh recommends Sean Maley

Technical Director

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.

Karen Peterson recommends Mireille Costandi

I have completed several loans/refis with Mireille over the past 20 years. I wouldn’t work with anyone else.
Aug 24, 2021

Ken Moll recommends Ken Dean

This is the second property we’ve financed through Ken Dean. Both times were excellent, but the second time was even easier as he already had most all of our information, so providing a few updates was a snap. Despite his being busy, there was never a time we couldn’t reach him or he wasn’t quick to respond to an email inquiry. Thanks Ken. Job exceedingly well done!!

Cynthia Salinas recommends James W. Argo

Jim Argo and his Team are amazing. Courteous, thorough and communicative. I felt they gave us great frequent updates and Jim was always cool under pressure and in the current market - pandemic, low rates, etc - that is saying a lot. Jim even answered emails when on vacation in Europe which was very thoughtful. Professional all around and I would recommend him to friends/family.

Alexandra H. recommends Tim Higbee

Tim was everything we never knew we needed! He took the time to walk us through the whole process, was always available if we had any questions, and generally made what could be an incredibly daunting and nerve wracking experience totally painless.

Jaydeen J Vicente recommends Alan Kirth

Alan is very knowledgeable and trustworthy. The entire process was smooth easy. I highly recommend!
Aug 16, 2021

Jason P. recommends Sean Maley

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!

Chuck Russell recommends Aisling Ferguson

Executive Director

Aisling gets the job done in record time. My realtor told me that no one ever managed to close a loan so quickly as Aisling. She takes the hassle out of buying or refinancing a home. I wouldn't consider a different broker.
