It is good to opt for hybrid mortgage than going for plain ARM. Hybrid mortgage, also called a fixed-period ARM, combines features of both fixed-rate and adjustable-rate mortgages. A hybrid loan starts out with an interest rate that is fixed for a period of years (usually 3, 5, 7 or 10 years). Then, the loan converts to an ARM. The beauty of a fixed-period ARM is that the initial interest rate for the fixed period of the loan is considerably lower than the rate will be on a mortgage that's fixed for 30 years.

• The smallest payment doesn't necessarily cover all the interest accrued during the month. In this "negative amortization" option, the borrower owes more at the end of the month than at the beginning, even after making a payment
