You want to purchase an office building in Brooklyn. The property contains 32,100 square feet of rentable space and is currently occupied by multiple tenants each with differing maturities on their respective leases. No lease is currently shorter than 1 year. The annual rent in the 1" year of ownership is $45.50/sqft. The vacancy rate is 15.5%. You expect to incur collection losses (from tenant default)on 5.5% of the square feet during your first year. 14. Suppose you buy the property at the asking price of $8,000,000 and own it for exactly 1 year. You make the down-payment in part (9). You collect the NOI in part (3). You make the annual mortgage payment in part (10). In two years, the NOI is expected to be the same. You sell the property at the end of year 1, at a cap rate of 50 basis points below the cap rate in part (11) and you pay off the loan balance when you sell. Compute the IRR on this investment
