When this guide is useful
This fictional case concerns a sale after improvements and depreciation changes.
The distinction that matters
The example separates sale proceeds, debt payoff, selling costs and asset basis history. The owner's net cash at closing is not the same as taxable gain.
A worked situation to investigate
A fictional investor sells a furnished rental after replacing appliances and implementing an earlier 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.
