Month To Month Leases

[Nicholas J Robichaud]

Hi everyone! I just purchased a three family in Pelham NH. I have my tenants on a TAW agreement at the moment. My question is when doing a month to month agreement like this do I need to have them sign a new agreement at the beginning of every month? Or does the first one signed stay in effect until they decide to move out? Or is this just a matter of wording in the contract? Any advise would be appreciated! Thanks!
