3 Day Notice in Toledo, Ohio

[Patrick Sergott]

I have my interpretation of the law in Ohio but am seeking input on when you can file a 3 day notice in Ohio. Here is my situation. 

Tenant's rent for February is $700. Rent was due on February 4th. Tenant has paid $100 toward the $700 thus owing $600 plus late fees. When am I able to file the 3 day notice? My property manager and I are not in agreement. 

Would love to hear your thoughts.
