If you have an Adjustable Rate Mortgage, your ARM is tied to an index which governs changes in your loan's interest rate and, thus, your payments. This page lists historic values of major ARM indexes used by mortgage lenders and servicers. Check the latest values of many of these indexes.
ARM holders can use these ARM indexes with our ARM Check KitTM to verify the interest rate adjustments on most types of ARMs.
