When this guide is useful
A rental replaces refrigerators or other separately identified items.
The distinction that matters
Keep the purchase, location, readiness and old asset record connected. Do not count an item in both a new purchase schedule and an existing study cost pool.
A worked situation to investigate
A landlord replaces appliances that were already separately tracked after an earlier cost segregation study.
The example is illustrative. Begin with the underlying event and its source documents, then separate missing facts from disagreements about their treatment. Work through the checks below in the order that matches your file, rather than treating a completed checklist as a tax conclusion.
Build a traceable handoff
Identify the affected person, entity or property and the relevant period. Keep original evidence, corrections and the reviewer's written conclusion connected. If the facts change after review, preserve the earlier version and ask whether the change affects implementation.
