We worked with Jonathan and Annette, who make such a wonderful team for obtaining a mortgage! They are personable, and all of our questions and concerns were addressed in a timely manner. They made the process seamless and enjoyable. Highly recommend Guaranteed Rate as a loan source.

JD Cortese and his team were amazing! Every step in the process was explained and documented clearly. Each member of his team made sure I understood the process and replied back quickly with any questions I had. I would recommend JD Cortese again and again.

Katherine H. 6/2017

As a first time home buyer, I was intimidated by the thought of buying a house. JD's team showed great patience explaining the intricacies involved with the loan process in a clear and concise manner. It was evident that they really take the time to help their clients. The effort and care they showed is very appreciated and I really want to thank all of them!

Charlene G. 4/2017

Reilly O'Toole is a fantastic team manager and led a great process from start to finish. Absolutely the best experience one could ask for. I can't stress enough how much of a positive impact Reilly and his team had on this process.

Tim H. 4/2017

Jonathan Kauzlarich did a fantastic job throughout the home-buying process. He was able to educate and advise us the entire way. He is a tremendous asset to your business.

Daniel D. 4/2017

It is great to work with Guaranteed Rate because they found a better loan for me and was able to purchase my home. Thank you!

Aracely S. 4/2017

Mallory was very responsive to all my questions. She's very caring, pleasant, respectful and knowledgeable. JD Cortese returned my initial call in less than an hour and that's awesome. He took time to come and meet with me when I stopped by the office. He is detail oriented and took time to explain the process and the numbers. Reilly O'toole, thank you for your quick response when Mallory was out. I appreciate your time and effort in making the process quick and seamless.

Emie P. 3/2017

JD and his team were great. Its a lot of paperwork and follow up (especially right before the closing) and they made it very organized and easy. I will be referring business to them in the future.

William P. 4/2017

Michael and JD really helped us through the process, was helpful, prompt, communicated well and and was never pushy. He really helped us through what we thought was an intimidating process. Kudos!

Jonathan M. 3/2017

Very smooth from beginning to end. GR personnel were always available to assist with any questions, etc.

Jack L. 3/2017

Everything went well I'm very happy with my loan process and agent.

Christopher S. 1/2017

Easy process! Love working with Guaranteed Rate!!!

Daniel P. 12/2016

JD Cortese and Reilly O'Toole simply were the best individuals I have ever worked with as it relates to obtaining a loan. They have great people skills, great organizational skills and was a pleasure to do business with. In the event I ever move again, Reilly and JD will be my first call!!!

Brent L. 12/2016

This is the second time we worked with JD and Guaranteed Rate after initially being referred by a friend and then refinancing our condo with them last year. Guaranteed Rate has a great reputation and we found that having a pre-approval letter from Guaranteed Rate strengthened our offer. The purchase of our home couldn't have gone any smoother. Our closing was completed in about an hour and everyone around the table marveled at how well it went. JD and his team are accessible and easy to work...

Mike B. 05/03/2016

Everything about the process was fantastic. I obtained a mortgage in 2011 from Bank of America and it was nowhere near this simple. I loved the online interface, where you could easily upload documents and see the checklist of what else was needed. So user friendly...I will definitely use Guaranteed Rate in the future when I'm looking to buy a home.

Kristin H - Battle Creek, MI | Feb. 2016

Jonathan was great!!!

Angela L. - Arlington Heights, IL | March 2015

JD and his team impressed me with how quickly they got everything done. Smooth, professional, fast. Couldn't ask for more!

C. Nelson - Palatine, IL | Nov. 2014

The team we worked with was amazing, they were helpful and everything went smoothly. The customer service was great and the fact the team made us feel very appreciated. They also were enthused about the whole thing as well. It made it very special for us. The best customer service I think I have ever received. A very easy process, who would have thought buying a house was the easiest thing I would ever do.

Alexander K. -- Sterling Heights, MI 3/3/2014

"Had a great experience with JD Cortese and his staff. I would recommend!"

Mark M. -- Bloomington, IL. -- 11/2013

“We were referred to JD Cortese and his team (Reilly OToole, Douglas Gool, and Mary Jordan). They were phenomenal to deal with and really helped secure an aggressive rate! We were insured everything was in order in time for our closing, and did it the whole time with a smile! I recommend JD and Guaranteed rate without hesitation!”

Nick L. -- Chicago, IL -- 03/2013

I just wanted to write you and let you know how great it was working with you. You and your entire staff are awesome! I've never had an experience with a lender that was so good, or easy to work with. Throughout the process, everyone was extremely reliable, professional, and informative. I had no idea the mortgage process could be so painless. If I know anyone in the market for a loan, I will be sure to send them your way.

Anthony M. -- 03/2013

Great experience all around! I highly recommend JD Cortese and his team because they rock!

Sara B. -- Chicago, IL -- 02/2013

JD was extremely helpful and treated our home loan with huge urgency and kept in contact at all times. The whole experience was wonderful and stress free!

Michael G. -- Norridge, IL -- 01/2013

My experience with your company was great. Very efficient & quick (just how I like to do things). JD is sharp as a tack. So are all of his assistants. I was originally referred by a friend. This is my 2nd refi through you. I have already recommended you to others. Yes, I would definitely come back and do business. Good overall experience.

Margaret M. Chicago,IL 3/2012

I thought everything went very well. As JD and his team will tell you, we had a unique situation with our mortgage, with funds flowing from multiple sources in addition to the fund provided by the loan. JD and the team did a nice job of getting their arms around the situation and coordinating the closing for a seamless transaction.

George L. - Winnetka, IL 2/2012

I felt like the Guaranteed Rate team was always on top of the ball and that there was always somebody available to answer my questions.

Max H. - Chicago, IL 8/2011

Once again, JD and his team shepherded my wife and me through the process expertly. Because our situation was far from cookie-cutter, it took some ingenuity to get a loan package that fit our needs. The rate JD found for us was surprisingly low. Preliminary approval was quick. Closing was delayed for reasons beyond our control. But JD made sure that we didn't lose our rate-lock, even though prevailing rates were rising. I couldn't ask for better service throughout.

Jason, Chicago, IL 60625

I had a great experience with Guaranteed Rate. Everyone responded promptly to my questions and concerns, explained everything thoroughly, and obtained exactly the product I asked for.

Elizabeth, Winnetka, IL 60093

My representatives (Kirk and JD) were helpful, polite and prompt. I felt like I could trust them and they were an honest business.

Jennifer, Chicago, IL 60605

Everything was great. JD, Kirk and their staff did an excellent job pulling my loan together in record time! I really appreciate their hard work. They seemed to be dedicated to my loan and situation for several days since I was so rushed to get the house purchased. THANK YOU!!
