I think the question is, can education be claimed as an expense on Schedule E?  That's a good question.  I have had clients who owned out-of-state rentals and wanted to deduct travel to check on them in person, insisting that the primary purpose of the trip was to inspect investments and not to visit the grandkids.  And I have had clients who owned rentals but were also self-employed in real estate, as agents or brokers.  They could deduct classes.  

Google's AI tells me that "Open Space" classes could be "A program at Yale that teaches environmental science to 6th grade students in New Haven, Connecticut."  Or, they could be "A yoga center that offers a variety of classes, including gentle yoga, basics and beyond, intermediate, and mixed levels."  I would have to see a nexus between whatever this class taught, and the rental properties owned by this unemployed landlady.
