Kellan Gregory recommends Aisling Ferguson

Aisling over delivers yet again! This purchase was particularly complex since my partner and I were both leveraging our finances to acquire our new home. Aisling was able to secure us the appropriate loan with a lower interest rate under a particularly short escrow. Communication was easy and Aisling was there whenever we had questions. You really feel like you have a champion working with you - highly recommend!

Rob McLaughlin recommends Foster Weeks

My husband and I recently completed a purchase of our first home, and we couldn't have been happier with the work that Foster did on our behalf. Every question we had (there were many) was answered thoroughly yet clearly by Foster. He was very supportive throughout the whole process and kept us up-to-date on everything that was happening with our loan. We felt confident throughout the whole process that we were working with someone who was at the top of his game. On top of all that, Foster is a super-nice guy who is easy to talk to.

Chris Diehl recommends Aisling Ferguson

Put simply, Aisling made it possible for me to purchase a beautiful home in the East Bay after a very lengthy search. With the quick turnaround required for closing and the complexity of my situation due to being an entrepreneur, there were a ton of hurdles to clear in a very compressed timeline. Aisling went the extra mile to get it done and I am deeply grateful for her extraordinary efforts! It's not clear it would have happened any other way.

giuseppe sircana recommends James W. Argo

President of engineering design and construction company

Easy review for me here: James and his team helped me about 1 year ago to obtain a loan for my own house; that went just quick and easy so, when I recently found myself in need of a loan for an office space for my company, I certainly had not to shop around. One more time James and his team handled my application professionally; I was educated and informed through all steps and everything went smooth and quick.
Thank you again!

My husband and I are repeat customers of Aisling's. She is smart, friendly, and efficient. We worked with someone else before her who was a nightmare -- I'm so grateful that we found Aisling!

Tiffany recommends Aisling Ferguson

Aisling is absolutely superb at her craft. My partner and I were first time homeowners. Aisling was informative and guided us through the loan process. She was dialed into the hot Oakland market. She worked really well with both the buying and selling agent. She is smart, fast and extraordinarily efficient. We are grateful for her awesome work—-we would not have our house without her help.

Aisling got us our home- for real! Because of her expertise, speed of business, and knowing the nuances of so many neighborhoods, she committed to a quick close - did it- and next the house was ours!

Community Education Coordinator

Aisling was awesome. She is great with her attention to detail and follow-up. Asiling created easy communication channels to get the necessary paperwork finalized (and very expediently) for our home refinance. I would recommend her to anyone looking for the services she provides.

It's been a pleasure working with Orlando on my challenging refi. He explained the procedure clearly and outlined all the steps that needed to be done. I would highly recommend Orlando to anyone looking to do a refi.

We had a small window of time to close on our dream home. Aisling was on it every day and made it happen! We are so grateful.

David R recommends Aisling Ferguson

We worked with Aisling with a short timeframe on a somewhat tricky transaction. She worked quickly, did a lot of back and forth with us to answer questions and help us understand what our options were, and ultimately got everything done quickly and easily.

Jim and Grace recommends Kevin Casey

Kevin Casey is top notch in our book as he helped us with out recent loan application for a rental property. We were denied by our initial bank loan application and he was able to work with us in a very timely basis and got us to close in about weeks. We highly recommend him. Very seasoned and knowledgeable! Thanks Kevin!

James and his team were there with us every step of the way. Great communication throughout the process and professional accurate advice. Easy to reach by phone or e-mail - even when he was traveling outside the country! Answered every question and got us great rates and a quick transaction. Had a firm grasp of our needs and took care of everything! Can't say enough good things about him!

client

Aisling competently navigated us through a 6-unit condo conversion - a massive feat! She worked directly with 3 of the 6 TIC owners on our refinance loans, and coordinated with the other owners to ensure everyone's ducks were in a row to all close on the same day. She acted as Project Manager in a way that was literally priceless. We got lucky enough to eek out a loan lock before rates skyrocketed, so I'm also grateful for that. I'd definitely hire Aisling again. For anyone navigating a condo conversion - you're in good hands.
