@earlvanze a STR can be active or passive despite material participation. the rules of IRC. 469 come into play.
this is from reg 1.469-1T
Exceptions. For purposes of this paragraph (e)(3), an activity involving the use of tangible property is not a rental activity for a taxable year if for such taxable year—
(A) The average period of customer use for such property is seven days or less;
(B) The average period of customer use for such property is 30 days or less, and significant personal services (within the meaning of paragraph (e)(3)(iv) of this section) are provided by or on behalf of the owner of the property in connection with making the property available for use by customers;
(C) Extraordinary personal services (within the meaning of paragraph (e)(3)(v) of this section) are provided by or on behalf of the owner of the property in connection with making such property available for use by customers (without regard to the average period of customer use);
(iv) Significant personal services—(A) In general. For purposes of paragraph (e)(3)(ii)(B) of this section, personal services include only services performed by individuals, and do not include excluded services (within the meaning of paragraph (e)(3)(iv)(B) of this section). In determining whether personal services provided in connection with making property available for use by customers are significant, all of the relevant facts and circumstances shall be taken into account. Relevant facts and circumstances include the frequency with which such services are provided, the type and amount of labor required to perform such services, and the value of such services relative to the amount charged for the use of the property.
(B) Excluded services. For purposes of paragraph (e)(3)(iv)(A) of this section, the term “excluded services” means, with respect to any property made available for use by customers—
(1) Services necessary to permit the lawful use of the property;
(2) Services performed in connection with the construction of improvements to the property, or in connection with the performance of repairs that extend the property's useful life for a period substantially longer than the average period for which such property is used by customers; and
(3) Services, provided in connection with the use of any improved real property, that are similar to those commonly provided in connection with long-term rentals of high-grade commercial or residential real property (e.g., cleaning and maintenance of common areas, routine repairs, trash collection, elevator service, and security at entrances or perimeters).
(v) Extraordinary personal services. For purposes of paragraph (e)(3)(ii)(C) of this section, extraordinary personal services are provided in connection with making property available for use by customers only if the services provided in connection with the use of the property are performed by individuals, and the use by customers of the property is incidental to their receipt of such services. For example, the use by patients of a hospital's boarding facilities generally is incidental to their receipt of the personal services provided by the hospital's medical and nursing staff. Similarly, the use by students of a boarding school's dormitories generally is incidental to their receipt of the personal services provided by the school's teaching staff.
average period of customer use
(C) Average period of customer use for class of property. In determining an activity's average period of customer use for a taxable year, the average period of customer use for a class of property held in connection with an activity is determined by dividing—
(1) The aggregate number of days in all periods of customer use for property in the class (taking into account only periods that end during the taxable year or that include the last day of the taxable year); by
(2) The number of those periods of customer use.
