Problem 5: John is considering the purchase of a lot. He can buy the lot today and expects the price to rise to $25,000 at the end of 10 years. He believes that he should earn an investment yield of 9 percent compounded annually on his investment. The asking price for the lot is $10,000. Should he buy it? What is the internal rate of return compounded annually on the investment if John purchases the property for $10,000 and is able to sell it 10 years later for $25,000?
