Our family of banks are committed to the local needs of communities in Southwest Montana. We have served those needs for over 35 years by extending the concept of personal banking to all our customers. We do this by getting to know them and taking the time to listen, then tailoring investment and deposit requirements to fit their individual lifestyles.
 

Our Bank can help with a wide variety of home financing options. Assistance is available for purchasing a new home or refinancing a present residence. The application process is easy and loan approvals are quick. Couple all this with friendly, personal service and the rest is easy.

 

An Equiline account makes bill paying a simple affair. Turn credit card balances, personal loans - even auto loans - into one, smaller monthly payment. Since Equiline is secured to the equity in your house, your interest rate will likely be lower, and you may be able to deduct interest payments on your tax return. (See your tax advisor for details.) Stop and see us today for more information on how you can save money and achieve a new measure of financial freedom.
