A Flexible Loan, Now with Fixed Interest Rates

Using the SmartLock* feature on your loan, you can convert a portion of your line of credit balance into fixed rate loans. This allows you to take advantage of lower interest rates when you know exactly how much you'll need to take out, while still giving you all the flexibility of a home equity line of credit.

The Flexibility of a Home Equity Line of Credit

With SmartLock, you never lose the flexibility in your HELOC. Once you've locked a portion of your loan, you can still use the rest of your available credit at any time and on anything you need.

The Stability of a Home Equity Loan

With SmartLock, a portion of your line of credit will have the stability of a loan. That means you'll lock in a low interest rate, know your monthly payments in advance, and have the ability to set up an automatic payment through your Bank of Oklahoma checking account.

Using SmartLock can help you consolidate debt and lower your monthly payments. See below for an example of how this could work for you.
