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!!

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.

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...

Kathryn G.

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.

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.

Christina Tretheway was an amazing advocate and customer service expert. She followed up every question, email, and phone calls/texts immediately without fail and accommodated us in every way throughout the process. I have never had a more positive experience purchasing real estate.

I love that everything was handled online or over the phone! The process was very easy for a working professional.

We worked with a team that was a well-oiled machine, easy to communicate with, incredibly informative through our first ever mortgage process, incredibly accommodating and really nice people, to boot! Many thanks for making a lifelong dream a reality!
