In the state of Georgia is is Legal for a landlord to do a inspection before a tenant move out of it not in the rental agreement?

My friend is moving out in about 2 months but her landlord want to do a walk through now not when she moves completely out. It’s not on the lease her house isn’t dirty or anything but it’s just odd that he want to do a walk through now instead of when she moves everything out and turn over her keys for her deposit! She isn’t on any housing program so it’s not required for him to just come when he feels like it! If anyone have any credible evidence or source that states other wise
