Fixed Rate Mortgages
The traditional fixed-rate mortgage has a constant interest rate and monthly payments that never change. This may be a good choice if you plan to stay in your home for seven years or longer. If you plan to move within seven years, then adjustable-rate loans are usually cheaper. When interest rates are low, fixed-rate loans are generally not that much more expensive than adjustable-rate mortgages and may be a better deal in the long run, because you can lock in the rate for the life of your loan.
These increasingly popular Adjustable Rate Mortgages (ARMs)—also called 3/1, 5/1 or 7/1—can offer the best of both worlds: lower interest rates (like ARMs) and a fixed payment for a longer period of time than most adjustable rate loans. For example, a "5/1 loan" has a fixed monthly payment and interest for the first five years and then turns into a traditional adjustable-rate loan, based on then-current rates for the remaining 25 years. It's a good choice for people who expect to move (or refinance) before or shortly after the adjustment occurs.
Adjustable Rate Mortgages (ARM)
When it comes to ARMs there's a basic rule to remember...the longer you ask the lender to charge you a specific rate, the more expensive the loan.
This loan has a rate that is recalculated once a year.
