3. Your firm would like to purchase a commercial warehouse building. The local bank has offered to finance the purchase by lending your firm $800,000 at 5% annual interest. The loan will be paid off using a balloon mortgage schedule that entails 20 annual (end-of-year) payments, with the first payment occurring a year from today (end of Year 1). The first 19 payments will be $60,000 each. The last payment (Year 20) will be a large balloon payment. What should the balloon payment in Year 20 be in order to fully pay off the loan?
