42 U.S. Code § 12808 - Second mortgage assistance for first-time homebuyers
The Secretary shall make available a model program under which units of general local government provide loans (secured by second mortgages) with deferred payment of interest and principal to first-time homebuyers.
The payment of any principal and interest on a loan under this section shall be deferred for not less than the 5-year period beginning on the date of the acquisition of the residence by the homebuyer.
The interest rate on the unpaid balance of a loan under this section shall be at least 4 percent.
A deferred payment loan assisted with amount  provided under a grant under this section shall be secured by a lien on the property involved, which lien shall be subordinate to the first mortgage on the property.
 So in original. Probably should be “amounts”.
