Unparalleled professionalism, decency and patience. Olivia Sherer especially. Conversations with her felt like I was talking to a friend who genuinely cared. That's because she did. So too did everyone I worked with: Jason Griesser, Amy Versace & Hailey Haney. I found myself completely surprised that anyone in the industry would actually care about my situation like they did!

One of the best in the business with years of experience. I would recommend to everyone I know

Working with Jason and his team was truly an exceptional experience from start to finish. From the very first conversation, they took the time to understand my needs, answer every question with patience and expertise, and guide me through every step of the process with clarity and professionalism. What stood out most was their communication. I was never left wondering about the status of my loan - Jason and his team kept me updated at every stage and made sure I felt comfortable and confident throughout the journey. They went above and beyond to make the process smooth, stress-free, and even enjoyable. Their knowledge of loan products and their ability to find the right solution for my situation was outstanding. They didn’t just process my application; they became trusted advisors who had my best interests at heart. I can honestly say that this is the best lending experience I’ve ever had. If you’re looking for a loan officer who is professional, responsive, and truly cares about his clients, look no further than Jason Griesser and his incredible team. I highly recommend them to anyone in need of mortgage or financing assistance—you’ll be in the very best hands.

This is the 2nd time working with Jason Griesser over the past 10 years and it only got better and easier. He is professional, communicative, knowledgeable, and patient. He always made me feel like I was his one and only client. Jason also took the time on multiple occasions to walk me through the process and gave me the best rate he could find. His team is also top notch. I will 100% use Jason and his team if I go through this process again in the future. You will be taken care of if you choose Jason to be your lender.

It was a smooth and easy process to work with Rate

Everyone I worked with, especially Krista, was very helpful and communicated well.

Everyone is friendly and attentive

This is my 2nd mortgage with Guaranteed Rate and the staff was helpful and knowledgeable

Fantastic communication & clear guide to next steps every part of the process. I felt very supported and comfortable.

Very thorough and responsive. Answered all of our questions along the way. Fought hard to get us a low rate

Rate got it done for me. Thank you to the whole team at Rate!

Personable. Friendly. Human to human interactions. Lightning fast close. Empathetic and razor sharp team.

Dominic was amazing to work with

My contact Joe O'Connor was amazing, but there were some blips with other parts of the process regarding the assessment and final papers for closing.

The whole process was simple from start to finish. It was night and day from my other mortgage firm I started with

Everyone I worked with communicated great and made things easy

Did a good job

The whole process of getting a loan to buy a house was made so easy by everyone I worked with

My sister has worked with GR for years and I was always very impressed with how professional and dedicated she was to her clients.

Great communication throughout the process and everything went quickly and smoothly!

I had a friendly, dedicated team that made me feel as though I was their only client. They were immediately available anytime I needed them and the process was not only seamless, but it was stress free! The systems used were also very easy to work with.

Fast, efficient, great communication

Everything was easy and fantastic

Ease of application, support throughout the process, responsiveness and kindness of agent

For being available 24/7 to help , explain and make things happen

I had a great experience, from information gathering to closing.

Very seamless and quick. Good updates on how things were progressing.

I'm very satisfied with your service.

As a first time home owner, Guaranteed Rate did an amazing job at helping navigate and complete the mortgage process. The online interface is simple and user friendly, conveniently centralizing all of the documents/to-do action items, so that I know exactly what needs to be done and where in the mortgage process we are at. The entire team did a phenomenal job of communicating with me and guiding me through the phases of the application, and they were always quick to respond to any questions I had.

First class service

Excellent communications and customer service

The service and rates are both unmatched

excellent service. always responsive. professionalism.

This is the second time we have used Jason and his team. Jason and his team were great to work with. They were informative and organized. He was timely in delivering documents and requesting what was needed for the mortgage process. Our closing was so smooth and quick all because of how he prepared us for the closing. I have recommended Jason to my friends and will continue to recommend him in the future.

The team was extremely responsive and helpful! They explained everything in detail and helped up to understand every step. We would highly recommend Jason and team.

I can't say enough amazing things about Jason and his team. I'll shout it from the rooftops. We have closed many times on other properties, but this experience was the most difficult and Jason + team navigated it so well. They made this process so easy. Not only was the rates and fees very competitive (some of the absolute best we found), but we had a difficult property that we were trying to finance (it was a fixer). Jason went OUT OF HIS WAY to work with his network to help us close on time. With rates changing, we will likely refinance and I wouldn't even think of going anywhere else as we are so grateful and impressed with how hard this team worked for us to get us into our dream property. Jason is a gem! Don't look anywhere else but with his team.

Jason helped me purchase my first home. He and his team made sure that I was informed through each step of the process. I would recommend him to anyone.
