Purchasing a Home

You don't have to wait to find the home you want to purchase before applying for your mortgage with First Interstate Bank.

In fact, it's best to submit your mortgage application before you begin your home search. That way, your mortgage lender can review your application and help you determine the price range that is most appropriate for you.


Pre-qualification is an excellent first step before you start your home search. By submitting your application early, you will have an opportunity to meet with your mortgage lender to review your application and help explain the price range in which you should search.

Pre-qualification involves a preliminary review of your finances to ascertain your debt to income ratio, which helps your lender determine what price range might be most suited for your search.

Refinancing Options

Refinancing your home essentially replaces your current mortgage with a different mortgage. Often, transitioning loans can decrease monthly payments, change loan terms, and provide other benefits.

Consult your mortgage lender to learn more about refinancing your home and how it may be able to benefit you, whether your mortgage is currently with First Interstate or another lender.
