Evict with no lease agreement

[Rob Westerman]

I bought a 4 family about 6 months ago. I inherited tenants with the building. I usually am not a fan of this, however 2 had been there for 20 plus years. All for tenants are month to month without a lease agreement. (I know I should have had then sign one). Now one of the shorter term tenants stop paying rent. I have no choice but to evict him. Are rules/laws different when a tenant has no lease? I am in Ohio. Thanks...
