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 52/2=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?
