automatic lease renewal question???

[Rochelle Wilkinson]

Question.. I have a tenant who just gave me notice .. Her automatic lease renewal started today on November 1st..she gave me notice 2 weeks ago.. we sent out letters 2 months ago asking if she was staying and she didnt return the paperwork.. she said she just found a great house to rent and she doesnt want to pass it up..I was told we should have her sub lease the apartment if she wants out of the lease..we are at 100% capacity and dont have trouble finding good quality tenants so should I let her out of the lease? or if she leaves would 
I take her to court for the whole 12 months lease since it literally just renewed today? my question is are automatic renewals solid??? if you read my back log you will see im new at this so be kind please.. this is an honest question? I dont want to be a jerk but she had mentioned if i dont let her out of the lease i can keep her deposit and she will just move anyway.. I said " well then we will see you in court" but wondering if the automatic renewal holds up?
