My mother owns a property in the city I live. She lives in another city. I leased the property for her and signed it as the landlord in my name. It was a 12 month lease. The lease is a standard NC Residential Lease Agreement. Tenants have paid the 12 months and are now in a month to month lease. My mother wants to ask them to leave with a 30 day notice. It is mid April and she wants the 30 days to be effective now having them vacate mid May. The tenant had paid all of April. Question: does the 30 day notice have to be effective starting at the END of April, which was paid in full or can the notice be effective now so they have until mid May to vacate.
