Jessica was AMAZING through the whole process and always available to answer questions. The closing attorney couldn’t believe how quickly she got the documentation completed. Took 9 days when the national average is 30!!

Jessica was an absolute pleasure to work with! She made herself available no matter the time of day to answer any and all questions during the process of getting our mortgage loan together. She made sure we were comfortable with the process and always kept us updated and informed. She jumped through several hoops for us and went above and beyond on multiple occasions. Can’t thank her enough for her thoughtfulness throughout the process and being apart of helping us secure our next home together❤️

They simplified the process for us and were very thorough in explaining things to us as first time buyers. They helped ease any anxieties and helped dispel a lot of the horror stories that we had heard about the mortgage and home buying process in general. They also got us our clear to close extremely quickly and pulled off our closing in less than a month from the offer acceptance. I would recommend them to anyone!

Very responsive and helpful

Throughout the process everything seemed to run very smoothly. Jessica, my loan officer kept me up to date at all times.

Guaranteed Rate (specifically Jessica Diaz) has assisted me in financing a home twice now. While the process had been stressful and overwhelming with other lenders, Guaranteed Rate simplifies things and explains everything from the documents needed, to programs that can provide down payment assistance. They do the tough stuff, which is such a huge relief when there are so many other tasks necessary when purchasing a home.

Excellent customer service

Because my loan officer was great!!!

The lending process was done very quickly and there was great communication between us and every member of the team

The ease of the whole process

For fully explaining, and very active responses with good availability for questions. Easy access to documents and your information. Great all around.

It was a seamless , non stressful process

Best people I’ve worked with

Jessica and her team are extremely knowledgeable, honest, and pleasant to work with. They were always available to answer any questions we had and are very grateful for their patience.

Jessica was incredibly- friendly, knowledgeable, and effective.

When you start the process of buying a house, you have a lot of details and questions that you need somebody to help you in finding the answers. In my case, I found Jessica and her team: they were giving me the answers ahead. The most I like is locking on a low interest rate. Thanks Jessica and the team.

We purchased our first home with the help of Jessica Diaz and Guaranteed Rate! Jessica and her team were prompt and very communicative. They helped us every step of the way and were able to close the deal on our home with remarkable efficiency and assistance. We would not hesitate to recommend her and Guaranteed Rate to anyone looking for a lender. For more information: My wife and I were with another lender that made our circumstances challenging but Jessica and her team came in to save the day at the last minute. We are incredibly grateful.

Jessica has been SO HELPFUL during our home buying experience. We were trying to purchase our first home which ended up falling through (at no fault of the buyers side) and she was so helpful keeping us updated and on track. When we did finally close on another property her team was quick to transition, keep us updated and provide for a super clear and easy closing process. Would highly recommend.

Jessica Diaz from Guaranteed Rate was the absolute best woman I could have ever had for help processing my new home loan. Jessica worked with me step by step through the whole process and answered any questions I had. The process moved fast and seamlessly with Jessica and her team at Guaranteed Rate. I used Guaranteed Rate about ten years ago for a different property and felt they did a good job for me, but Jessica surpassed that with her knowledge and ability to guide me through everything with the new home purchase. I literally felt like I had a friend helping me with my loan. Hats off to Jessica and her team!

From the moment we were pre-approved to the day we closed on our dream home, Jessica and her team went above and beyond, making the entire process seamless and as stress-free as one could have hoped.

She took the time to understand our finances and guided us through our various options available, ensuring we felt confident in our decisions. Her expertise and clear communication gave us the peace of mind we needed, especially considering we were moving from San Francisco to Chicago. To the point of our remote finance search; Jessica and team worked timely and with great consideration of our time zone differences. She was readily available after hours. This level of service and professionalism was beyond the standard expected. The second point we must mention is the speed at which she and her team operated. Within a mere 11 days, we went from being pre-approved to finding our ideal home and securing approval for the mortgage. This level of efficiency was simply unparalleled, and it made a world of difference in this competitive real estate market. When it came time to finalize the deal with the sellers, Jessica and her team were nothing short of astonishing. They worked tirelessly, coordinating with all parties involved, and within just one day, they had everything in place for a smooth closing process. It was truly a testament to their dedication and expertise. Throughout the entire journey, Jessica's attentiveness and willingness to answer our questions promptly were commendable. We always felt like a priority. Jessica and her friendly demeanor navigated what could have been a stressful life experience with ease. In addition to her individual brilliance, it must be mentioned that Jessica is backed by the exceptional team at Guaranteed Rate. Their collaborative efforts and coordination ensured that nothing fell through the cracks. We are grateful to Jessica Diaz and Guaranteed Rate for making our dream come true.
