You can invest in one of two investments listed below. You cannot invest in both. If your cost of capital is 6%, which one should you invest in, and why?

Investment A A small apartment complex. This complex has 50 units and has an asking price of $5,000,000. You expect net income of $25,000 per month for 12 months. In months 13, 14, and 15 you plan to make capital improvements that will result in net income of -$10,000 in each month. After that, you expect to earn $40,000 until the end of year 10, when you expect to sell the property for $4,000,000.

Investment B A small office building. This building has an asking price of $6,750,000. If you purchase it you will have to make repairs and upgrades for the first two months, which will result in net cash flows of -$150,000 and -$100,000 respectively. In month 3 you will have net revenue of $25,0000, $50,000 in month 4, and then in 60,000 each month until you expect to sell the building for $4,500,000 at the end of year 8 (month 96.)
