To buy a $130000 house, you take out a %12 (APR compounded monthly) mortgage for $100000. Five years later, you sell the house for $175000 (after all other selling expenses). What equity (the amount that you can keep before tax) would you realize with a 30 year repayment term? Note: For tax purpose, do not consider the time value of money on $30,000 down payment made five years ago
