Pay your mortgage

AHSTI now provides the option for customers to make online mortgage payments! 

The following tips are to help you with the first time you access the online payment system:


  • The first time you access the system, you will need to register.

  • Click on "Register: First-time users must register." It is located in the grey box under the login section. 

  • You will need your Loan Number to register. Your loan number can be found on your monthly mortgage statement. If you do not have a statement please call 687-6263. Let the person know that you need your loan number. 

  • You will also need to enter your social security number. 

  • Once you confirm your account, you will be able to log in and make your payment.

  • Please keep your password in a safe place. 

  • Please note that if you enter the wrong password three (3) times you will be locked out and will be directed to call a 1-800 number to unlock your account.

  • If you have any questions, email with your name, the issue, and a phone number we can reach you at.
