1. You want to buy house. After calculating costs you find that major maintenance will cost $2000 every 3 years and monthly utilities will cost $200/month. The rate of return is 5% compounded monthly. You also take a depreciation on the house for the first 5 years. If you buy the house for $200,00, how much would you need to sell the house for in order to make a profit after 15 years?
