A building was purchased 10 years ago for $3,000,000. During that period straight-line depreciation (2%/year) was used to reduce the taxable income from this investment held in an LP. The building sold for $5,000,000. Improvements of $500,000 were made to the building just before it was sold. Note: the improvements were not capitalized (no depreciation was taken for the improvements in any prior tax year). What is the basis for this property? Show your work for partial credit.
