Suppose you own a small company that is contemplating construction of a suburban office block. The cost of buying the land and constructing the building is $755.000 Your company has cash in the bank to finance construction. Your real estate adviser suggests that you rent out the building for two years at $32,750 a year and predicts that at the end of that time you will be able to sell the building for $862,000 Thus there are now two future cash flows-a cash flow of C = $32,750 at the end of year and a further cash flow of C2 = ($32,750 + 862,000) = $894750 at the end of the second year. a. Calculate the NPV of the office building venture at Interest rates of 7. 12 and 17%. (Negative amount should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.) Net present value at 79 Not present value at 12% Not present value at 17% b. At what discount rate (approximately) would the project have a zero NPV? Check your answer by calculating the NPV at your approximate rate; it should be close to zero (Enter your answer as a percent rounded to the nearest whole number.) % Approximate discount rate
