Fixed Rate Mortgage
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 might be a better option. As a rule of thumb, it may be harder to qualify for fixed-rate loans than for adjustable rate loans. 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 ARMS 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. These loans offer a fixed monthly payment for a period of time, then turns into a traditional adjustable-rate loan, based on then-current rates for the remaining term of the loan. 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.
With this loan, the interest rate is recalculated every month. Compared to other options, the rate is usually lower on this ARM because the lender is only committing to a rate for a month at a time, so his vulnerability is significantly reduced.
