New home owner!

Sean's exceptional performance truly made our home-buying experience outstanding. His unwavering commitment and swift actions played a pivotal role in securing the home of our dreams. Without his dedication and tireless efforts, we might have missed out on this incredible opportunity. The speed at which we were able to close is a testament to Sean's persistence and hard work. We are immensely grateful for his professionalism and expertise, and we wholeheartedly recommend his services to anyone in search of a dedicated and efficient real estate professional. Five stars doesn't seem enough to express our appreciation for Sean's remarkable contribution to our home-buying success.

Adele & Scott McCall recommend Kathy Derangi

Kathy Derangi deserves all five stars and more! She helped us with a long distance
mortgage and was innovative, helpful, on top of the myriad of details that San Francisco and California require, participated in joint phone calls when insurance agent got balky, walked us through many a detail to make sure we understood, and, in short, she was GREAT to work with! We cannot imagine anyone being able to do a better job.

Rosalie L recommends Vince Breen

I recently had the pleasure of working with Vince Breen from Guarantee Mortgage to secure a mortgage for my dream home, and I couldn't be more impressed with his professionalism, expertise, and dedication to helping me achieve my goal.

From our initial consultation to the closing of the deal, Vince Breen went above and beyond to ensure that every aspect of the mortgage process was smooth and efficient. He took the time to understand my financial situation and goals, offering personalized advice and guidance every step of the way.

One of the things that stood out to me most was Vince Breen's responsiveness and accessibility. Whenever I had questions or concerns, he was always just a phone call or email away, ready to provide clarification and support.

Not only did Vince Breen help me secure a competitive mortgage rate, but he also navigated the complexities of the loan application process with ease, making the entire experience stress-free and seamless.

Thanks to Vince Breen's expertise and dedication, I am now the proud owner of a beautiful home that I thought was out of reach. I wholeheartedly recommend him to anyone in need of mortgage services. If you're looking for a mortgage loan officer who truly cares about your financial well-being and goes the extra mile to help you achieve your homeownership dreams, look no further than Vince Breen. He's simply the best in the business!

I'll definitely be recommending Vince Breen to all my friends and family for their future mortgage needs. Thank you, Vince Breen, for your outstanding service and support!

Chelsea Donlin recommends Cecelia Tyeskey

Cecelia was great to work with for our first home purchase. She educated us on the process and guided us through the details/considerations for us to think through. Once we were ready to make an offer she pushed everything through quickly to make our offer competitive and worked with our realtor to seal the deal. I am so thankful for Cecelia's help!

Philip Oxford recommends Orlando Diaz

Orlando and his team were truly amazing to work with. During my first home purchase I had my original loan fall through and was recommended to work with Orlando and he was able to work out a true miracle in a very short time window and allowed me to hit my closing date with no delays! He was always open to any and all questions and worked tirelessly even though he was about to head out on vacation. I cannot thank him and his team enough for the tremendous amount of amazing work they have done for me. I highly recommend working with them.

Amalia M. recommends Aisling Ferguson

We have been trying to figure out how to buy the home we were renting for a long time. Aisling had many conversations with us before things actually got going--helping us figure out a path forward. We were first time buyers and chose to work with a lawyer instead of a realtor--Aisling held our hands the whole way. She was fast, clear, and cooperative with all the randos we dragged into the deal along the way. We are so grateful for her.
