Prorated rent return?

[Jonathan Yungel]

Hello fellow BP,

I own several rental properties in Atlanta GA and have run into a problematic tenant that has recently vacated one of my properties. the lease was for 24 months. she paid rent on time most of the time and fulfilled the complete lease ending on 5/31/2016. She informed me recently that she was expecting prorated rent  as she vacated and turned over keys 5 days prior to end of lease. I provided her the walk through sheet and itemized list of damages when i inspected home on 5/27, she handed over keys on this day. additionally we have recently returned her deposit minus damages, she cashed. 

walk through performed 5/27. this was originally scheduled for 5/30, she informed me that home was vacant and cleaned, thinking i would meet her any day she wanted. 

Am i liable to pay prorated rent return of 5 days? i can not find any legal statement that a landlord is responsible for prorating rent for walk through being performed 5 days prior to lease termination schedule as of 5/31. she has been a very difficult tenant to say the least. this property has been sold as of today.

I'm in a quandary.
