A bоrrоwer hаs secured а 30-yeаr, $150,000 lоan at 7 percent with monthly payments. Fifteen years later, the borrower has the opportunity to refinance with a 15-year mortgage at 6 percent. However, the upfront fees, which will be paid in cash, are $2,500. What is the return on investment if the borrower expects to remain in the home for the next fifteen years?
