I do not personally like month to month from either side of it -- as a landlord, I want a tenant who commits for at least a year to avoid turnovers (understanding a bad one will leave, anyway, but hopefully they've been mostly screened out), and from the renter's side (which I've been on as well), I do not want to put the effort into moving in somewhere unless I am assured I won't have to move again for at least 6 months.

They will appreciate that education much more if they are accountable I assure you .
