When Interest Rates
only tell Part of the Story - Understanding Points
When home buyers are looking for a new mortgage, or going
to refinance an existing one, they typically pay close
attention to the interest rate associated with it. While
the interest rate is one of the most important pieces of the
mortgage agreement, it is not the whole picture in terms in
what you will ultimately pay. Did you know that points
also play a role in how much you will ultimately pay for the
house you are getting ready to buy? Using points wisely
can save you money in the long run if used wisely.
Each point that you buy will reduce your interest rates by
1/8th (typically) of a percentage point, thus to knock off 1%
of your interest rate you would need to purchase 8 full
points. Each point typically costs 1% of the total
mortgage amount. Thus, if you are taking out a $200,000
mortgage one point would end up costing you $2,000. In
essence, you are paying the lender up front for a reduction in
the amount of interest over the life of the loan.
So when does it make sense to use points? They are
usually only beneficial to the home buyer (in terms of saving
money over the life of the loan) when the buyer intend to stay
in the home for an extended period of time. Those who
plan to live in the home for less than 5-10 years may see no
benefit at all, and actually end up paying more in the long
run if they buy points up front. Let's take a look at an
example.
Suppose you decide to take out a mortgage for
$200,000. The rate you are quoted is 6%. If you
take out the mortgage for 30 years your monthly payment at 6%
would be $1,199.10. If you decide to purchase 4 points
to lower your interest rate to 5.5% you would end up spending
$8,000 to buy the points. This will save you
$63.52 per month in payment costs. Thus you would need
to stay in the house for at least 126 months (or 10.5 years)
to get back your up-front investment of purchasing the
points. Over the life of the mortgage note, you would
end up paying $208.808.08 interest with the points versus
$231,676.38 without for a savings of $22,868.30 in interest
over the life of the loan.
When deciding on whether or not to purchase points up front
the general rule of thumb is to approach it from a
conservative point of view. Nowadays people are moving
more often and the house you buy today probably won't be the
same house that you stay in all of your life. Some
experts suggest that you should only buy points when the
payback period is less than 5
years.
