Early Lease Termination by a Military Tenant Due to Official Transfer

[Gracy Josh]

I have rented my single family house in Georgia to a person who is employed in military. The tenant has signed the lease which states that 2 months of notice + 1 month of rent to bear the expenses involved in finding a new renter in the case of early termination. Now the tenant has got his transfer order to another location and they gave us 35 days of notice. I'm new to renting a house to military person and I'm not sure of the Georgia law about the lease termination due to official reasons. I need to know what the tenant will owe me in this situation. Help me with the required information so that I could make this process smoother for both the parties.
