Does the tenant pay anything? On what pay period?(weekly, monthly,etc)
In MN a non-lease tenant is able to be given notice at the end of the previous pay period to be out by the next. So for month to month you’d have to give 30 days, week to week it 7, etc. Not sure on the non-paying part however. You may be able to boot them immediately but only you know the details of your agreement.
