Georgia - Abandoned Property

[Mallory Thompson]

I have a duplex in Georgia, it's section 8. We just purchased and one of our tenants moved out. They gave notice to move out, and left behind two full size couches, a tv some expensive tennis shoes and of course a bunch of trash - yay. 

I've googled how to handle abandoned property, but all the advice comes after an eviction. This tenant willingly left our property and we are still in contact with her. We are being nice and told her to give us a time when she plans to get the rest of her belongings this week. She's being semi-communicative and is only trying to respond via phone calls/no texts (yes I know there has to be a reason) but I'm getting fed up with her and need to know what the law says - what is the process for us removing the property so we can being working to get it rented out again and what are her rights as a tenant? 

We did the inspection last night, she has not returned the keys to us.
