Part 2: Refinancing. In 2005, Tom and Betty Wrights bought a house. They did not have sufficient cash to pay for it, so they put 35% down and financed the rest $276,250 at the then-interest rate of 4.85% for 30 years. The Wrights are recently retired and are living on a fixed income. With sudden increase of health expenses, they started to worry about being able to make house payments. Since interest rates have dropped, they consider refinancing the mortgage. Their options are: Plan A: 15-years loan at 2.85% or Plan B: 30-years loan at 2.35% Show your detailed calculations.
