When credit is advanced by note or contract and payment is required in regular equal installments and the note or contract will mature before the note or contract is paid in full, a payment which may be larger than the regular payment will fall due.
When a mortgage is written with a monthly payment that is less than required to satisfy the note rate, the unpaid interest is deferred by adding it to the loan balance.
An index is a widely used published interest rate that lenders use to set the interest rate on loans. 10-year U.S. Treasury securities are often used for 30-year fixed-rate loans. ARM loans are commonly based upon the, one-, three-, and five-year U.S. Treasury security yields; the monthly average interest rate on loans closed by savings and loan institutions; or the monthly average costs-of-funds incurred by savings and loans. Lenders adjust the interest rate up or down on an adjustable rate mortgage by measuring the difference between a current index rate to the ARM interest rate, and adding a margin.
