Christina and her team were very helpful and made our home busy process very easy. I would recommend them to anyone buying and home and especially first time home buyers!

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...

This experience was painless and efficient. Everybody I had to deal with was very professional and answered all of my questions. I have already recommended Guaranteed Rate to my sister and some friends. Thank you so much.

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!

Whitney and Jon T.

Christina and her team were great - responsive, smart, and helpful! Thanks again!

Kathryn G.

Christina was awesome! She was so patient, understanding, and easy to work with. I would highly recommend her.

Katie B.

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.

Megan H.

The process was so intimidating but once Christina started helping me out it was a breeze

Thomas D.

We had a very difficult closing process due to legal issues on the sellers end. Guaranteed rate made everything as seamless for us as possible. We went through multiple loan extensions and renewals and they were always willing to take the time to answer any questions I had. My sister recommended Guaranteed Rate to me, and I would highly recommend them to others in the future.

Malinda W.

The process could not have been easier or faster, thanks!

Forrest V.

Our lender couldn't have been better. They were always available to answer any questions I had and I really felt like they had our best interest in mind.

Malinda W.

I have refinanced twice with Guaranteed Rate and now have my new mortgage for my new home. The team is outstanding in their communication and organization. They also did a fantastic job of talking to my lawyer, real estate agents, financial planner, etc. and while I was informed, I didn't have to act as a go between for all parties which was a MASSIVE relief.

Jocelyn F.

Christina Longo and her team are a pleasure to work with!

Zachary K.

I went to Guaranteed Rate because a friend had recommended Christina Trethewey - she had worked with Christina in the past and had a great experience. I found the process pretty easy - having a secure website to upload the documents was very convenient.

Cynthia M.

Christina was a pleasure to work with. As first-time homebuyers, the whole process of applying for a mortgage was very daunting at first, but Christina put us at ease right from the start. She made the whole process simple and stress-free -- from getting pre-approved, to understanding our mortgage options and answering our questions, to getting our final loan approved. I would happily recommend Christina to anyone looking for a loan officer.

James V.

Great company!
