Thank you for that thorough response.
Your interpretation sounds reasonable, and aligns with many definitions of "placed in service" across various resources. But it seems that even with the thoroughness of your of research, there still remains a high level of ambiguity and uncertainty, which makes tax/financial planning difficult.
Taxpayers may attempt to gather enough evidence to meet as many of the 9 bullet points as possible. Proving 1, 4, 5, 6 should be straightforward using the documents established during the sales process. However, is there a recommendation how to exactly determine and prove 2, 3, 7, 8, and 9?
