Sarah purchased a condo for $200,000 with a $25,000 down payment and a $175,000 bank loan. The mortgage is to be amortized in just 15 years with an interest rate of 3% per year, compounded monthly. 10 years later, the value of her condo has risen to $280,000 and she would like to sell her property. How much does she still owe on her mortgage? What is her equity in the condo at this point?
