Oppenheimer Bank is offering a

30-year

mortgage with an APR of

5.25 %

based on monthly compounding. With this mortgage your monthly payments would be

$2,000

per month. In addition, Oppenheimer Bank offers you the following deal: Instead of making the monthly payment of

$2,000

every month, you can make half the payment every two weeks (so that you will make

2652/2=26

payments per year). With this plan, how long will it take to pay off the mortgage if the EAR of the loan is unchanged?
