Life Changer

Buying a home is the single biggest financial investment most of us will ever make, and trusting Karissa Peters with the process was literally life changing. Karissa was incredibly easy to communicate with and made sure to be available at all times. She took the time to carefully explain all scenarios and when things changed, she was the first to reach out to inform me. As a first time homebuyer in this ever changing market, it's been difficult to come up with a significant down payment. I worked with Karissa through many scenarios and she was able to secure me a down payment assistance grant that made it possible for me to purchase my first home. Not only did the funds make it possible to purchase my home, but it made it possible for me to live within my means when it came to the mortgage. It's an amazing feeling walking into your home after what most folks say is a scary & ambiguous process but this was not the case for me thanks to Karissa. The entire process could not have been more straight forward. A huge thank you to to Karissa Peters and the NSB team for helping me find my home.

Karissa, by far above all others

Karissa was a joy to work with! From our very first of many conversations she made me feel at ease about the whole process and made me confident that I was receiving the best rates and the lowest fees possible. I know very little when it comes to mortgages and Karissa made it as smooth and as simple a process as possible. I honestly could not have gotten it done without her!! Thank you so much Karissa!!

5 stars!! Pleasure to work with!

Karissa was amazing to work with! She was very professional and helpful on our first home purchase. every question was answered no matter what time we called/texted. She was able to explain everything in terms we understood and made sure to give us every option available. I would recommend her to anyone, and especially first time home buyers who might need a little more assurance throughout the process.

The best person for the job!

Karissa was amazing from the first moment we spoke over the phone. Knowledgeable, informative and worked on our mortgage as if it were her own! We’ve bought several homes and I can’t stress enough how easy it was to work with her. Will definitely recommend her and use her again!

Responsive, Professional and treats you like family

From the moment we met with Karissa about our mortgage, I trusted she was going to take care of our family as we bought our first home. She helped us figure out the best financial solution based on our needs and level of comfort. She helped us through the home buying process seamlessly. She also got us the most competitive products and rates that she could and it truly beat all the competition out there. She was always responsive, able to pivot easily when we changed our approach to offers we were considering, and she ultimately secured us the financing we needed for our forever home without any trouble. If you want to feel like you're being taken care of like family, work with Karissa!
