Briarvane Corporate Center: every component and its recovery period

Fictional acquisition price of $5,800,000 includes $1,150,000 of nondepreciable land; the $4,650,000 component basis is an illustrative allocation, not an appraisal, construction bid or tax conclusion. The tables below list every component this walkthrough builds, the recovery period it is assigned in this illustration, and its illustrative allocation.

Illustrative assumptions, not a valuation or tax conclusion. A real study's allocation comes from the specific property's own records.
