You are to receive $7,500 each year as payment for a loan you extended.Under the current terms,you will be paid the same amount forever,and never get back the principle.The first cash flow is in 1year.You believe that the appropriate discount rate for these payments is 6%.If the borrower instead wanted to pay off the loan in 15years,how much (at minimum)would they have to offer you per year to convince you to change the terms?
