Real Estate is not passive In my first year of real estate I've had many duties annoyances. 

1. Setting up Tenants payments(normal)
2. Pipe exploded in bathroom
3. Flooding foundation wall
4. Section 8 housing annoyances. Long paper work processing, inspections...
5. Appliance repairs
6. Roof repairs
7. HVAC repairs

This all ran me 10k and a lot of my time. This is a warning to all people entering real estate. I'm happy I bought the property but there is absolutely no free lunch here.
