Terminating the property management agreement in a Foreclosure

[Account Closed]

Property I bought at FC auction in NC has a tenant who leased it through a property management company. As per NC laws, tenants in a FC situation has certain rights and they may stay in the property at least 1 year after the deed has been transferred to my name under the same lease conditions they signed with the previous owner. 

This is OK by me as long the tenant continues to pay the rent. However, I manage my own properties and I do not want the property management company involved as the middle man. Can I terminate the property management agreement the previous owner signed with this property manager without any liabilities? What should I watch for example security deposit and such.
