Of course that’s a benefit of renting. How does that relate to the OP _homeowner_ saying one downside of ownership is they don’t have a single number to call for any maintenance issues?

I guess on the face of it, it's not related. I didn't read his comment as literally lamenting the lack of a number, or even someone to orchestrate, but rather to imply that there's nobody on the hook for it in all facets. With a landlord, you just call the number and magic happens and it's free to you (in theory, not always in practice).
