My Core Values


The most important part of the mortgage transaction is trust. You are trusting us with your most confidential and private information. This is why honest and ethical behavior is at the foundation of every transaction. 



You have a lot of choices when it comes to getting a home loan. Getting a mortgage can sometimes be frustrating and stressful. By having a service first mentality helps make sure you are comfortable and happy with our process.


As we like to say, it's not about us, it's about you. Flexibility to meet changes in the market and with your loan program is key. We are not happy if you're not happy. Being flexible on our part, to meet your needs, is what we strive to do.

Educational Videos

Educating our clients about the mortgage process is key. We also want to add value by giving you more than just "mortgage this" and "mortgage that".  We have put together a library of videos that encompass a lot of information regarding Real Estate, Mortgage, and just being a home owner in general.

If we ever need a lender in the future, Jennifer is the person we will be calling and referring people to. During a new experience, you couldn't ask for more help and excellence in customer service!

Jennifer was incredibly knowledgable about everything related to lending and real estate. She answered all of the questions we had and provided excellent guidance when asked.
