I have worked with Guaranteed Rate several times in the past, and I would very much want to work with them again in the future. I trust the entire team, most especially the Loan Officer, who I have worked with in the past, even before she worked at Guaranteed Rate. She was the sole reason I applied for a loan with Guaranteed Rate, and I have come to trust and appreciate her entire team. I would, and I have, several times in fact, recommended my friends and relatives use Guaranteed Rate - and...

Christina Longo Trethewey and her team of Jeanne Singleton, Mark McLaughlin and Carissa Pape were all exceptional, easy to work with and talk to. They were extremely responsive and worked weekends, nights to get the information the lender was looking for to get this mortgage accomplished. I truly appreciate their efforts, professionalism and dedication. Thank you all!!

Christina and her team are awesome. They all deserve immediate raises and all expense paid trips to anywhere in the world that they would like to go! (Also anyone aggregating these surveys should be included on the these) Your attention to this matter would be appreciated. Thanks! Happy Year-end. Enjoy the Holidays!

Hello Christina, What a nice surprise we received in the mailbox earlier this week. A box of personalized cookies from your office, including one with a picture of our newly moved-in house. It is so thoughtful. We truly appreciate it. I don't think you would mind, but is it okay if I share the picture on my facebook feed? Even without the cookies, we have been blown away with the level of organization and smoothness of the processes and steps involved by your office and Guaranteed Rate in our...

Margaret T.

I was so impressed with Guaranteed Rate, Christina Trethewey and her team. They were so easy and helpful to deal with. They were pleasant and made sure I knew what was going on every step of the process. They had everything done on a timely manner, I didn't have to worry about anything. If I need to get another loan for anything I will contact them in a second.

Kate S.

THANK YOU so much for the wonderful cookies and the good wishes. What a lovely gesture - and the special cookie layered with the home photo was uniquely thoughtful. We enjoyed eating most of them very quickly. It was indeed a real pleasure working with you and team - we felt we were in great hands the entire time, and very appreciative of the teamwork that made the process so smooth. We're enjoying our new home, and slowly getting to meet our kind neighbors. Have a wonderful summer, and Thank...

Jon and I want to thank you for your commitment to our cause of purchasing our first home. You have gone above and beyond despite all the road blocks we faced but we are so thankful to have been referred to you. Your professionalism, willingness to communicate often and overall demeanor is a testament as to why you are the best in the biz! It was a pleasure working with you and hopefully we can work with you again in the future. Thanks again!

Christina and Mark were instrumental in making this a seamless experience. It was very clear what was needed, when it was needed and both were very courteous and responsive when I had questions. The whole team was great, but Christina and Mark stood out to me.
