What are the respective advantages of 15-year and 30-year terms?
The 30-year fixed rate mortgage remains the standard mortgage, with an array of valuable benefits designed especially for buyers who expect to stay in their homes for a long time. Because the borrower pays more interest than principal for the first 23 years, the tax deduction is substantial. And as inflation causes income and living expenses to increase, your unchanging monthly mortgage payments account for a relatively smaller portion of income as the years go by.
As you'd expect, a 15-year monthly mortgage means higher monthly payments than an equivalent 30-year loan ... but not as much higher as you may think. At the same rate of interest, payments on the 15-year mortgage are roughly 20-25 % higher than a loan that takes twice as long to pay off. And one of the benefits of choosing a 15-year mortgage is that you can generally get a lower interest rate for an otherwise similar loan. Another advantage is faster equity build-up because a larger portion of your early payments are going to pay off principal. This makes the 15-year mortgage an ideal alternative for couples approaching retirement or anyone else interested in owning their home free and clear as quickly as possible.
