You are analyzing a commercial real estate investment that generates a net operating income of $5,000,000which increases by 3.5 percent per year. The purchase price is $58 million, the holding period is 10 years, the nominal income tax rate is 28 percent, the recapture tax rate is 25 percent and the long-term capital gain tax rate is 15 percent. A lender is willing to provide financing for the 10 year holding period with a 25 year amortization period for a fixed rate of 7 percent based on a loan to value ratio of 75 percent (25 percent equity). Calculate the before and after tax IRR and NPV based on a discount rate of 4% above the going in cap rate and a terminal cap rate of 1% over the going in cap rate. The cost of sale is three percent. Remember: going in cap rate-1st years noi /purchase price.
