"You owe $140,000 on your mortgage which runs for an additional 6 years. You currently pay 6% interest. For simplicity, you calculate the annual payment at $28,471. You are considering refinancing the loan at 5% in which case the annual payment would be $27,582. The refinancing cost would be 4% of the remaining balance. How much will you save (indicate as a positive number of dollars) or lose (indicate as a negative number of dollars, e.g., -2000), if you refinance? For this problem, do not consider income tax effects."
