Most of which you would have anyway. I never cared about incremental costs for internet, electricity, etc. if any. I could have probably collected double-digit dollars per month during COVID but I wasn't even officially remote anyway.
The standard residential plan I had was fine for any work purposes. As far as I'm concerned, incremental needs for normal work are in the noise. I did have outages now and then but they were pretty much for reasons that would have applied to any business service as lines were down.
