The average mortgage rate for a 30-year fixed has been
around, or just below 4.0%, which is what we will use in our example. An
average mortgage amount of $300,000 at 4.0% will cost the homebuyer $1,432.25
per month for principal and interest. The difference in the monthly payment for
0.25% increase in the rate (to 4.25%) is $43.57 per month, or $522.84 per year.
Not a significant difference, but there are a lot of things you can do with
$500.00 extra per year. When you add it up over the life of your 30 year loan
the total is $15,685.30.
Since the Federal Reserve has promised to continually
increase rates, the longer you wait, the higher your monthly payment and cost
to borrow money for a home becomes. Because we don’t know for sure when these
gradual increases will happen, it’s hard to predict exactly when the right time
to buy a home will be. Of course, the sooner you make your decision, the better
you will do on your interest rate. For example, the same $300,000 mortgage
amount at a 5.0% fixed rate will increase to $1,610.46 per month in principal
and interest. That’s a difference of $178.21 per month. Only 1% difference in
the rate and you are paying over $2,000 more per year for your mortgage. That
could be a nice, modest vacation. Over 30 years that is $60,000 – a lot of nice
vacations!
The same mortgage amount at 6.0% interest is now $1,798.65
per month, or $366.40 per month more in Princeton and interest on your payment.
That’s $4,396.80 per year. Over the life of a 30-year mortgage that’s a grand
total of $131,901! That’s enough money to finance a college education, or even a
few years of retirement. It doesn’t sound so bad when you are talking about a
quarter-of-a-percent, or even 1-2 percent higher than today’s rates. But when
you start to do the math it really adds up over the length of the loan.
