(a) One- to four-family dwellings; maximum term of mortgage; adjustments in effective rate of interest

The Secretary may insure under any provision of this subchapter a mortgage involving property upon which there is located a dwelling designed principally for occupancy by one to four families, where the mortgage provides for periodic adjustments by the mortgagee in the effective rate of interest charged. Such interest rate adjustments may be accomplished through adjustments in the monthly payment amount, the outstanding principal balance, or the mortgage term, or a combination of these factors, except that in no case may any extension of a mortgage term result in a total term in excess of 40 years. Adjustments in the effective rate of interest shall correspond to a specified national interest rate index approved in regulations by the Secretary, information on which is readily accessible to mortgagors from generally available published sources. Adjustments in the effective rate of interest shall (1) be made on an annual basis; (2) be limited, with respect to any single interest rate increase, to no more than 1 percent on the outstanding loan balance; and (3) be limited to a maximum increase of 5 percentage points above the initial contract interest rate over the term of the mortgage.

(b) Written explanation of mortgage features

Terms Used In 12 USC 1715z-16

  • Contract: A legal written agreement that becomes binding when signed.
  • Fiscal year: The fiscal year is the accounting period for the government. For the federal government, this begins on October 1 and ends on September 30. The fiscal year is designated by the calendar year in which it ends; for example, fiscal year 2006 begins on October 1, 2005 and ends on September 30, 2006.
  • Fixed Rate: Having a "fixed" rate means that the APR doesn't change based on fluctuations of some external rate (such as the "Prime Rate"). In other words, a fixed rate is a rate that is not a variable rate. A fixed APR can change over time, in several circumstances:
    • You are late making a payment or commit some other default, triggering an increase to a penalty rate
    • The bank changes the terms of your account and you do not reject the change.
    • The rate expires (if the rate was fixed for only a certain period of time).
  • Interest rate: The amount paid by a borrower to a lender in exchange for the use of the lender's money for a certain period of time. Interest is paid on loans or on debt instruments, such as notes or bonds, either at regular intervals or as part of a lump sum payment when the issue matures. Source: OCC
  • Mortgage: The written agreement pledging property to a creditor as collateral for a loan.
  • Mortgagee: The person to whom property is mortgaged and who has loaned the money.
  • Mortgagor: The person who pledges property to a creditor as collateral for a loan and who receives the money.
  • Truth in Lending Act: The Truth in Lending Act is a federal law that requires lenders to provide standardized information so that borrowers can compare loan terms. In general, lenders must provide information on Source: OCC
  • Variable Rate: Having a "variable" rate means that the APR changes from time to time based on fluctuations in an external rate, normally the Prime Rate. This external rate is known as the "index." If the index changes, the variable rate normally changes. Also see Fixed Rate.

The Secretary shall require that the mortgagee make available to the mortgagor, at the time of loan application, a written explanation of the features of an adjustable rate mortgage consistent with the disclosure requirements applicable to variable rate mortgages secured by a principal dwelling under the Truth in Lending Act [15 U.S.C. 1601 et seq.].

(c) Number of mortgages and loans

The aggregate number of mortgages and loans insured under this section in any fiscal year may not exceed 30 percent of the aggregate number of mortgages and loans insured by the Secretary under this subchapter during the preceding fiscal year.

(d) Adjustable rate mortgage with initial fixed rate of interest

(1) The Secretary may insure under this subsection a mortgage that meets the requirements of subsection (a), except that the effective rate of interest—

(A) shall be fixed for a period of not less than the first 3 years of the mortgage term;

(B) shall be adjusted by the mortgagee initially upon the expiration of such period and annually thereafter; and

(C) in the case of the initial interest rate adjustment, is subject to the 1 percent limitation only if the interest rate remained fixed for 3 or fewer years.
