An engineering firm constructed a small office building 5 years ago. They financed it with a bank loan for $450,000 over 15 years at 6% interest, compounded monthly. The loan can be repaid at any time without penalty. The loan can also be refinanced through an insurance company for 3% over 20 years, compounded monthly. The new loan has a 5% loan initiation fee, which will be added to the new loan. Generate a spreadsheet for each of these options with these columns: month, interest, principal payment, balance.
