For a single member LLC which is treated as a sole proprietorship, or an individual, generally the activity is reported on Sch C. However, rental property is treated differently. If no substantial services are provided, the activity is reported on Sch E. Unless you are considered a real estate professional, the activity is also considered passive and subject to the rules of passive activities.
However, if substantial activities are provided along with the rental property, such as meals, daily house keeping, etc., this would be akin to a hotel/motel/B&B, then it would be considered earned income and reported on Sch C.
A single member LLC, unless it elects to be treated differently, defaults to Form 1040, Sch C, unless rental property, then Sch E.
