Not exactly. The amount of time you spend on your rental properties, the term, and the responsibilities you mentioned do not necessarily dictate Schedule C treatment for the income.
Your rental income would properly be reported on Schedule C if you provided "significant services to the renter, such as maid service" or you were a "real estate dealer".
