Aspen Valley Storage has 1,800 units. Each unit is 100 square feet and rents for USD $100 a month. The firm is considering installing climate-control in 550 of the units, so that those units can be used to store items that would be damaged by excessive heat or cold, such as art work. The installation is expected to cost USD $500,000, and Aspen Valley's monthly utility bill is expected to increase by USD $3,750 if the conversion takes place. The climate-controlled units are expected to rent for USD $130 a month. If the appropriate discount rate is 15% per annum, what is the NPV of the project? Assume all cash flows are perpetuities.
