You are a financial analyst constructing a multiyear proforma to value a potential property acquisition. As part of the analysis, you are considering the most likely scenario for a certain space for which the current tenants lease will expire at the end of 2028. You estimate the following: the probability the existing tenant renews is 50 percent; if the tenant renews, you will need to spend an estimated $5.00/SF to upgrade the space; should the tenant not renew, it will take $15.00/SF to modernize the space for a new tenant; and you expect there will be six month of vacancy. Leases in this property are triple-net with the owner responsible for operating expenses associated with vacant space. Operating expenses are expected to be $5.50 in 2029, while market rent for triplenet leases is expected to be $14/SF. What is the expected property before-tax cash flow forecast (on a per sq. ft. basis) you will put in year 2029 of your proforma for this space?
