If you qualified as a real estate professional for 2017, report income or losses from rental real estate activities in which you materially participated as nonpassive income or losses, and complete line 43 of Schedule E (Form 1040). If you also have an unallowed loss from these activities from an earlier year when you didn’t qualify, see Treatment of former passive activities under Passive Activities, earlier.
My favorite type of semi-passive income was rental property because it was a tangible asset that provided reliable income. As I grew older, my interest in rental property waned because I no longer had the patience and time to deal with maintenance issues and tenants. Online real estate became more attractive, along with tax-free municipal-bond income once rates started to rise.
