4. A real estate investor is considering purchasing a small warehouse. Analysis has resulted in the following facts: - The asking price is $450,000. - There are 10,000 square feet of leasable area. - The expected rent is $5 per square foot per year; rents are expected to increase 5 percent per year. Since the property is leased to an AAA-grade tenant for 25 more years, no vacancy factor is deducted. - The tenant will pay all operating expenses except property taxes and insurance. These two expenses will equal 20 percent of the effective gross income (EGI) each year. - The investor can borrow 80 percent of the total cost for 20 years at an interest rate of 7 percent with monthly payments and upfront financing costs equal to 3 percent of the amount borrowed. - 85 percent of the total acquisition cost is depreciable over the useful life of 39 years using the straight-line method (no personal property). - The investor expects to sell the investment at the end of year 5 . - The investor's ordinary income tax rate is 30 percent. - No capital expenditures have been made since acquisition. Compute the after-tax cash flows from annual rental operations over the five-year housing period
