An investor is considering purchasing a retail complex that is projected to generate $6750 in net operating income (NOI) in the first year and will be sold after 5 years. Suppose that NOI will grow by 4% per year. If the purchase price is expected to be $51000 and the sale price is expected to be $63000, what is the net present value (NPV) of the investment in the office building? Use a discount rate of 10%.
