Security Deposit for Unpaid Utilities

[Sam Lofton]

Hello,

     I'm a real estate investor in Columbus, Ohio. Some of my tenants' lease is about to expire and I am not resigning with them. They have an outstanding water bill and their previous landlord had to take them to Small Claims Court for not paying the bill at their old residence. Am I able to use part of their security deposit to pay this off? All other utility bill debts follow the tenants but the water bill is ultimately on me if they do not pay. My lease clearly states that the tenants are responsible to pay all utilities used in association with the property. 

Thanks in advance!

Sam
