This applies to affluent individuals with top 1% income, as well as those that need to pinch pennies.

I typically like to do at least 60-day notice and let them know I am trying to make the process smoother and don't want to put them in a pinch.

Personally I'm not sure that I would ever do it on my own residence, but it doesn't seem like a bad solution for rental properties where every penny is being pinched as @Mark Fries suggested.
