Raising rent on Month to month

[Jim S.]

On m2m lease how do you raise the rent? Send a email & letter obviously but do you have them sign it or is a 60 day notification sufficient? I know I only need to give 30 day notice but I like to give 60. Do you do the same for any changes in lease? Do you need formal language? I know I might be over analyzing things, just looking for opinions. There's plenty of them on here, but that's a good thing, right.
