1. An office building has three floors of rentable space with a single tenant on each floor. The first floor has 20,000 square feet of rentable space and is currently renting for $15 per square foot. Three years remain on the lease. The lease has an expense stop at $4 per square foot. The second floor has 15.000 square feet of rentable space and is leasing for $15.50 per square foot and has four years remaining on the lease. This lease has an expense step at $4.50 per square fuxit. The third floor has 15,000 square feet or leasable space and a lease just signed for the next five years at a rental rate of $17 per square foot, which is the current market rate. The expense step is at $5 per square fout, which is what expenses per square foot are estimated to be during the next year (excluding management). Management expenses are expected to be 5 percent of effective grass income and are not included in the expense stop. Each case also has a CPI adjustment that provides for the base rent to increase at half the increase in the CPI. The CPI is projected to increasc 3 percent per ycar. Estimated operating expenses for the next year include the following: page 383 Property taxes S100,000 Insurance 10,000 Utilities 75.000 Janitorial 25,000 Maintenance 40.000 Total $250,000) All expenses are projected to increase 3 percent per year. The market rental rate at which leases are expected to be renewed is also projected to increase 3 percent per year. When a lease is renewed, it will have an experise stop equal to operating expenses per square foot during the first year of the lease. To account for any time that may be necessary to find new tenants after current leases expire and new leases are made, vacancy is estimated to be 10 percent of EGI for the last two years (years 4 and 5). a. Project the cffective gross income (ECT) for the next five years. b. Project the expense reimbursements for the next five years. c. Project the net operating income (NOT) for the next five years. d. How much does the NO/ increase (average compound rate) over the five years? c. Assuming the property is purchased for $5 million, what is the overall capitalization rate (going-in ratc)
