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

Forrest V.

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!

Boris D.

The process was simple, uncomplicated and transparent.

Randall W.

Christina and her awesome team made our refinance a breeze. From start to closing, all aspects of the process were handled professionally and efficiently. I would not hesitate to work with them again and would highly recommend them to everyone!

John N.

Christina and her associates were all very professional and helpful. I appreciate how patient they were explaining the process to me.

James M.

Christina and her entire team were awesome. This was a first-time home purchase for us, and they were very helpful every step of the way. They were also prompt in responding to all of our questions, no matter how small or silly. We were very happy. Thanks again!

Alyssa M.

Great team from start to finish. Every member was able to explain and answer every question I had!

Michael W.

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.

Mark R.

I have watched other people really struggled with their home finance this was so simple. I started to wonder if I was doing something wrong! However everybody made it so easy and they were so organized and the process was so available digitally that it made the experience really good.

Jocelyn F.

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

Brooke S.

Christine and her team were amazing. They were always available and answered all of our questions and concerns quickly and effectively. We would absolutely recommend her and her team in the future without hesitation! Thank you!

Carlos-Luis B.

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!

Lindsay C.

Christina Longo Trethewey exceeded our expectations. Always available to answer questions. As first time home buyers- she is exactly what we needed.

Katelyn A.

Christina is great! It can be a little confusing to know who to reach out to with questions because so many people are involved, but Christina always came through, patiently explaining my many questions. She is approachable and flexible and easy to reach. My only criticism for GR is that the generated emails are a bit confusing if you are a first timer... I got 3-4 emails saying my loan was approved at different points and this can be misleading, when in reality you can still lose your loan up...

Rose R.

Christina and her team are the best! She has done a great job for my clients and it was nice to get to see first-hand how unbelievable her service is. Such a quick and easy process. Thanks, again, Christina!

Michael M.

Christina was a dream to work with. She made a very stressful process simple and easy to understand. She was communicative the whole way through and I always knew what to expect. She was such a professional and I'd recommend her to anyone buying or refinancing a home.
