Carol just made a $250,000 down payment on a $1,000,000 house, and is paying the rest via a 25- year mortgage. Her bank requires her to re-finance every five years. The bank currently offers a nominal interest rate of 10%, compounded semi-annually, and paid in monthly installments. She decides to accept these terms. What will Carol still owe on her mortgage in five years when she refinances (i.e., after she has made 12 x 5 = 60 monthly payments)
