Lease termination letter delivery

[Evan D.]

Hello,

I just closed on my first house hack (duplex in Columbus, OH) with inherited tenants. I need terminate the one unit's month-to-month lease. Is there a best way to do this? I currently live out of state so I was thinking certified mail would be best. The tenant already knows I will be formally terminating the lease but I wasn't sure what the best way to delivery it was. Thanks in advance!
