Voluntary move-out after eviction appeal

[James York]

I filed an eviction and ruling in my favor with magistrate court. The tenant appealed and requested a jury trial (stall tactic) which was scheduled for September. She has now voluntarily moved out, but gave 5 days notice of her intent to vacate. Two part question. CAN I retain rent from her security deposit until it is release? SHOULD I or should I just be thankful she's gone? The eviction was not over money and it is in NC.
