What is an Adjustment Date and Initial Interest rate?
An adjustment date is the day when the interest rate changes on an adjustable rate mortgage (ARM). After an initial period where an ARM loan interest rate remains the same, the rate changes on the adjustment date to reflect the new ARM loan rate. The ARM loan rate will then continue to adjust over the remaining life of the loan as described in your Note. An initial interest rate is the starting interest rate of an adjustable rate mortgage (ARM). This initial interest rate on an ARM loan is fixed for a certain period of time, and then adjusts to reflect overall market rates.
What is an amortization schedule and how can I see it?
An amortization schedule is a schedule showing the effects of making principal and interest payments over the life of your loan as it relates to the loan balance and interest paid. It can be a useful tool to help determine the effects of making more than the required monthly payment, or in observing how much of your payment is applied to the principal reduction versus interest over the life of your loan. You can see your amortization schedule by visiting the Amortization Calculator page of your online account and submitting the needed inputs to calculate your results.
