Investors & landlords

Thank you, also, can I get your thoughts about whether this should show up on schedule C or E? I'm a bit confused because my average length of guest stay for the year was 6.3 (so less than 7) and I did sometimes bring the guests treats, towels, and/or other supplies during their stay but I didn't do daily cleaning so I don't know if this passes the "substantial services" test. 

I overall have about a $22K loss from the STR activity that I'd like to use to offset W2 income. Does it matter if I put it on schedule C vs E?
