what is the answer to this?

1. In December 2018, Tammy acquired an office building in downtown Syracuse, New York for $630,000. The building was originally constructed in 1932 and is a certified historic structure. Tammy quickly realized that substantial renovation would be required to keep and attract new tenants. The renovations, costing $870,000, were of the type that qualifies for the rehabilitation credit. The improvements were completed and on January 12019 the first tenants moved in. Yay! a. Explain the purpose of the tax credit for rehabilitation expenditures and describe the general characteristics of its computation. b. Compute Tammy's rehabilitation tax credit for the year the property was placed in service - 2019. c. Determine the depreciation deduction for 2019 (assume for this problem that apartment buildings like this one use straight line depreciation over a 40 year life). d. What is the adjusted basis in the property at the end of 2019
