You acquire a small office building for $6M. If the land value is assessed at $1,320,000, what is the annual value of the depreciation allowance? Assuming that you have made no capital improvements on the building, what is the book value of the property after five years? If you sell the building for $7.5M after five years, what is the total capital gains tax due given the tax on capital appreciation is 15% and the depreciation recapture tax is 25%?
