Five years ago, a borrower incurred a mortgage for $200,000 at 10 percent for 30 years, monthly payments. The current market rate is 8.5 percent for 25-year mortgages.

The borrower’s opportunity investment rate is 9 percent. If the borrower intends to hold the mortgage financing for 25 more years, should she refinance at the present time? (You must show your work)
