Guaranteed Rate proved to be a critical asset in navigating California's competitive housing market. Their pre-eligible status, rather than a typical pre-approval, made my offer stand out. The ability to close quickly was another major advantage. Combined with a secure and intuitive online platform and a highly responsive team, I had a fantastic experience.

Profesional, intentive, and quick response time.

Amazing team! Super helpful, responsive, and fast! We closed in 12 days and no one could believe it.

Very easy to use great communication

Rodger Maxwell was my loan officer and he makes everything stress free

Because they did everything right and they bossed me around politely!

I have worked with Dianne Cosby for several loans and she has been excellent. She listens to me and my requirements and finds me the best possible rate under the market condition.

We've had excellent communication and rapid and effective response from the team of professionals at Guaranteed Rate

I've referred clients to Guaranteed Rate before, specifically to Dianne Crosbyt

The whole team did such an excellent job really sticking to our extremely fast closing period. I also just really appreciate it. Dianne lending her own personal experience when we were struggling to make a decision about our home.

I had a great experience.

I am a long-time customer. Guaranteed rate and Dianne's team always delivers.

Great customer service from beginning to end

The follow up on the interest rate changes.

We would recommend Dianne Crosby and Monika Hayes. They are amazing and lovely to work with on our loan.

Great communication, attention, follow-up, flexibility, and forthrightness, as well as personal and professional engagement with our financial goals.

Dianne and her team were a pleasure to work with. They were extremely quick to respond to our communications. They took time to help us when we had questions and made sure we fully understood every step of the process. Our escrow period went very smoothly with no problems. We closed in 15 days and now have our dream home!

Monika, Dianne, and the entire team were wonderful to work with.

Repeat customer. Love you guys.

The team was quick, efficient and aided the closing of a very fast escrow.

Great service and very responsive. Great rate on my mortgage

Dianne and the team were always available to take our call and answer any questions we asked.

Great team! Super fast and very informative. Only 1 piece of feedback: would have loved if all of the documentation needed had dates attached to them so that I would be able to prioritize and ensure that everything is delivered on time.

The Crosby Team is absolutely the BEST Mortgage Lender in the Bay Area! If you are purchasing a home and need a mortgage in the Bay Area, then I recommend Dianne Crosby and her team. They helped me buy a home in Oakland, and the process was simple. They have also helped most of my family and friends purchase and refinance their properties. I recommend them to everyone!

Dianne is amazing. I found my dream home 2 days before offers were due, and Dianne was replying to my emails at 11pm to make sure it all went through. Dianne and her team answered all my first-timer questions and everyone I spoke with was encouraging and patient throughout the process. The online portal is simple and easy to navigate. Thanks Dianne, Anthony, and everyone else at GR who made it happen!!

Dianne and her entire team were so wonderful to work with and I would highly recommend them! It was our first home purchase/mortgage, so we needed some additional guidance and Dianne was always happy to provide it. She and her team were super responsive, efficient, professional and friendly and got us a great rate. They made the entire process as painless as possible and we were very satisfied with the result!

Dianne Crosby and her whole team at Guaranteed Rate are amazing to work with. We used them to buy our first home, refinance that home and now to buy our second home. Each time they made a stressful process easy. Thank you again Dianne and team.

Communication was incredible! the whole team kept us apprised of every step and updated me very quickly when new documents needed to be signed or a new detail was needed to move the process along.

Dianne Crosby has helped me and my family purchase and refinance several homes in the Bay Area. She and her team are fantastic and I can confidently say she got us the best rates possible. Dianne also went above and beyond throughout the lending process to make sure we got the home of our dreams. I recommend anyone looking to buy or refi to give her a call.

Excellent company with dedicated and knowledgeable staff. They earn top grades from us for their professionalism, expectation management, and streamlined process. Our refi closed faster than anticipated and we would highly recommend their company for mortgage lending services. Thank you Dianne & Guaranteed Rate!

Dianne Crosby's business, Guaranteed Rate, has streamlined the re-financing process perfectly. It wasn't difficult because it's very well organized and I would highly recommend it.

Dianne and her team were amazing—they made sure we closed on time and got the best rate. They were also incredibly responsive and helpful throughout every step. We wouldn't have our dream house today if not for them!

I have been working with Dianne for more than 20 years. She helped me finance my first ever home purchase in Berkeley. In other words, she helped me achieve the impossible - buying a single family home as a single woman without that 20 percent down. I continue to work with her even in Los Angeles and she always finds me the most competitive rates.

Dianne and her team helped us get financing and close on our house incredibly quickly. The process of buying a house is incredibly intense, especially when condensed into about 3 weeks. We only have positive things to say about Dianne, she was a pro and worked with us very closely to buy our first and hopefully forever home.

Nov 1, 2021

Dianne and her team were fantastic, honest, fair, efficient and friendly, and get our full recommendation!!

Oct 30, 2021

Dianne and her team were extremely helpful, efficient, and friendly during the pre- and mortgage approval process, which is complicated and time-consuming. Dianne also made sure we locked in a great low interest rate. I would highly recommend her team.

Excellent responsive service in obtaining and closing my home refinance loan. There have been some issues with and post-closing confusion as to loan servicing, and I hope and expect that Guaranteed Rate is able to smooth out this process for borrowers and match its excellence in the pre-servicing operation. Overall, I would highly recommend Guaranteed Rate. I have done many real estate financings over time and Guaranteed Rate has been the overall best by far.
