NOTICE TO BORROWER
IMPORTANT INFORMATION ABOUT THE ADJUSTABLE-PAYMENT, ADJUSTABLE-RATE LOAN
PLEASE READ CAREFULLY
(at least 10-point bold type)
You have received an application form for an adjustable-payment, adjustable-rate mortgage loan. This loan may differ from other mortgages with which you are familiar.
I. GENERAL DESCRIPTION OF ADJUSTABLE-PAYMENT, ADJUSTABLE-RATE LOAN
The adjustable-payment, adjustable-rate mortgage loan is a flexible loan instrument. This means that the interest, monthly payment and/or the length of the loan may be changed during the course of the loan contract.
The first flexible feature of this loan is the interest rate. The interest rate on the loan may be changed by the lender every six months. Changes in the interest rate must reflect the movement of an index that is selected by the lender. Changes in the interest rate may result in increases or decreases in your monthly payment, in the outstanding principal loan balance, in the loan term, or in all three.
The lender is required by law to limit the amount that the interest can change at any one time or over the life of the loan. The law does not specify what these limits are. That is a matter you should negotiate with the lender.
You may also want to make inquiries concerning the lending terms offered by other lenders on adjustable-payment, adjustable-rate mortgage loans to compare the terms and conditions.
Another flexible feature of the adjustable-payment, adjustable-rate mortgage loan is the monthly payment. The amount of the monthly payment may be increased or decreased by the lender every six months to reflect the changes in the interest rate. State law prohibits the lender from increasing your monthly payment by more than 7.5 percent per year. There may be circumstances, however, in which you, the borrower, may want to increase the amount of your monthly payment beyond the 7.5 percent limit. This option would be available to you whenever changes in the interest rate threaten to increase the outstanding principal loan balance on the loan.
A third flexible feature of the adjustable-payment, adjustable-rate mortgage loan is that the outstanding principal loan balance (the total amount you owe) may be increased from time to time. This situation, called “negative amortization,” can occur when rising interest rates make the monthly payment too small to cover the interest due on the loan. The difference between the monthly payment and the actual amount due in interest is added to the outstanding loan balance.
Under the terms of this mortgage, you as a borrower would always have the option of either incurring additions to the amount you owe on the loan or voluntarily increasing your monthly payments beyond the 7.5 percent annual limit to an amount needed to pay off the rising interest costs.
Continual increases in the outstanding loan balance may cause a situation in which the loan balance is not entirely paid off at the end of the 30-year loan term. If this occurs, you may elect in writing to repay the outstanding principal all at once, or with a series of fixed payments at a fixed rate of interest for up to 10 years.
The final flexible feature of the adjustable-payment, adjustable-rate mortgage loan is that you may lengthen the loan term from 30 to up to 40 years. Extending the loan term will lower your monthly payment slightly less than they would have been had the loan term not been extended.
II. INDEX
Adjustments to the interest rate of an adjustable-payment, adjustable-rate mortgage loan must correspond directly to the movement of an index which is selected, but not controlled, by the lender. Any adjustments to the interest rate are subject to limitations provided in the loan contract.
If the index moves down, the lender must reduce the interest rate by at least the decrease in the index. If the index moves up, the lender has the right to increase the interest rate by that amount. Although making such an increase is optional by the lender, you should be aware that the lender has this right and may be contractually obligated to exercise it.
The index used is [Name and description of index to be used for applicant’s loan, initial index value (if known) and date of initial index value, a source or sources where the index may be readily obtained by the borrower, and the high and low index rates during the previous calendar year].
