All About Adjustable-Rate Mortgages
Adjustable-rate mortgages (ARMs) differ
from fixed-rate mortgages in that the interest rate and monthly payment
can change over the life of the loan. ARMs also generally have lower
introductory interest rates vs. fixed-rate mortgages. Before deciding on
an ARM, key factors to consider include how long you plan to own the
property, and how frequently your monthly payment may change.
Why choose an adjustable-rate mortgage?
The low initial interest rates offered by ARMs make them attractive during
periods when interest rates are high, or when homeowners only plan to stay
in their home for a relatively short period. Similarly, homebuyers may
find it easier to qualify for an ARM than a traditional loan. However,
ARMs are not for everyone. If you plan to stay in your home long-term or
are hesitant about having loan payments that shift from year-to-year, then
you may prefer the stability of a fixed-rate mortagage.
Components of adjustable-rate mortgages
Adjustable-rate mortgages have three primary components: an index, margin,
and calculated interest rate.
- Index
The interest rate for an ARM is based on an index that measures the
lender's ability to borrow money. While the specific index used may
vary depending on the lender, some common indexes include U.S.
Treasury Bills and the Federal Housing Finance Board's Contract
Mortgage Rate. One thing all indexes have in common, however, is that
they cannot be controlled by the lender.
- Margin
The margin (also called the "spread") is a percentage added
to the index in order to cover the lender's administrative costs and
profit. Though the index may rise and fall over time, the margin
usually remains constant over the life of the loan.
- Calculated interest rate
By adding the index and margin together, you arrive at the calculated
interest rate, which is the rate the homeowner pays. It is also the
rate to which any future rate adjustments will apply (rather than the
"teaser rate," explained below).
Adjustment periods and teaser rates
Because the interest rate for an ARM may change due to economic
conditions, a key feature to ask your lender about is the adjustment
period--or how often your interest rate may change. Many ARMS have
one-year adjustment periods, which means the interest rate and monthly
payment is recalculated (based on the index) every year. Depending on the
lender, longer adjustment periods are also available.
An ARM can also have an initial adjustment
period based on a "teaser rate," which is an artificially low
introductory interest rate offered by a lender to attract homebuyers.
Usually, teaser rates are good for 6 months or a year, at which point the
loan reverts back to the calculated interest rate. Remember, too, that
most lender will not use the teaser rate to qualify you for the loan, but
instead use a 7.5% interest rate (or calculated interest rate if it is
lower).
Rate caps
To protect homebuyers from dramatic rises in the interest rate, most ARMs
have "caps" that govern how much the interest rate may rise
between adjustment periods, as well as how much the rate may rise (or
fall) over the life of the loan. For example, an ARM may be said to have a
2% periodic cap, and a 6% lifetime cap. This means that the rate can rise
no more than 2% during an adjustment period, and no more than 6% over the
life of the loan. The lifetime cap almost always applies to the calculated
interest rate and not the introductory teaser rate.
Payment caps and negative amortization
Some ARMs also have payment caps. These differ from rate caps by placing a
ceiling on how much your payment may rise during an adjustment period.
While this may sound like a good thing, it can sometimes lead to real
trouble.
For example, if the interest rate rises
during an adjustment period, the additional interest due on the loan
payment may exceed the amount allowed by the payment cap--leading to
negative amortization. This means the balance due on the loan is actually
growing, even though the homeowner is still making the minimum monthly
payment. Many lenders limit the amount of negative amortization that may
occur before the loan must be restructured, but it's always wise to speak
with your lender about payment caps and how negative amortization will be
handled.
