When this guide is useful
This fictional case concerns a property used by guests and the owner's family.
The distinction that matters
The scenario distinguishes personal stays, genuine repair visits and unoccupied days. A blocked calendar entry does not establish its tax classification.
A worked situation to investigate
A fictional cabin owner blocks dates for family visits, maintenance and gaps between guest reservations.
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.
