30 versus 60 day notice

[Cameron Pendergraft]

Hello all,

We recently closed on a duplex with inherited tenants on month to month leases in Kansas City. Both leases are under market rent and we plan to have the raise rent discussion but we're not sure of how much notice we need to give tenants. We plan on cancelling their old leases and signing them to market rent on our own lease. From my understanding, we need to give 60 day notice for a rent increase but only 30 day notice of lease cancellation for a month to month in Missouri. Seeing as we're cancelling their lease but also intend to raise rent, I'm not sure what amount of notice to give each tenant. Can anyone offer some insight?
