Pros and Cons of Biweekly Payments


Many people are paid biweekly. Those who align their mortgage payments with the date of their paycheck won't have to worry about making sure they save enough out of their paycheck to cover their home loan payments.

Most home loans across the United States incorporate a 30-year loan term. Most of the early payments on longer duration loan go toward paying interest.

Each year has 52 weeks in it, which is 26 bi-weekly periods. People making 26 payments which are half of their regular monthly payment are effectively making a 13th monthly payment which is applied entirely to the principal of the loan. This single extra payment per year builds home equity faster and can end up saving around 5 or 6 years on the life of the loan compared to a normal 30-year amortizing loan.

Any early repayment in the loan which goes toward principal extinguishes debt that will not accumulate any interest for the remainder of the loan period.

Making Extra Mortgage Payments.


Some companies charge a fee for managing biweekly payments. These fees often exceed the interest savings from employing the strategy, and when they do they ultimately do not save homebuyers any money. Instead they become an unneeded expense.

While paying more on a home means the home will be owned sooner, it also means the remainder of the consumer's budget will be a bit tighter as they are spending more paying off their loan faster.

If the homeowner defaults & goes into foreclosure before the loan term is up then the bank will own the property & any extra payments won't have benefited the foreclosed home buyer.
