Taxpayer uses this material participation method:(2) The individual's participation in the activity for the taxable year constitutes substantially all of the participation in such activity of all individuals (including individuals who are not owners of interests in the activity) for such year;E.g., they buy operating STR in December, don't hire a property manager, housekeeper or landscape maintenance guy until January.
