(2) The service member is released from active duty or state active duty after having leased the rental premises while on active duty status and the rental premises is 35 miles or more from the service member’s home of record prior to entering active duty;
(3) After entering into a rental agreement, the service member receives military orders requiring him or her to move into government quarters;
(4) After entering into a rental agreement, the service member becomes eligible to live in government quarters and the failure to move into government quarters will result in a forfeiture of the service member’s basic allowance for housing;
(5) The service member receives temporary duty orders, temporary change of station orders, or state active duty orders to an area 35 miles or more from the location of the rental premises, provided such orders are for a period exceeding 60 days; or
(6) The service member has leased the property but prior to taking possession of the rental premises receives a change of orders to an area that is 35 miles or more from the location of the rental premises.
(c) The notice to the landlord pursuant to subsection (b) of this Code section shall be accompanied by either a copy of the official military orders or a written verification signed by the service member’s commanding officer.
(d) In the event a service member dies during active duty, an adult member of his or her immediate family may terminate the service member’s residential rental or lease agreement by providing the landlord with a written notice of termination to be effective on the date stated in the notice that is at least 30 days after the landlord’s receipt of the notice.

(f) The provisions of this Code section shall apply to all residential rental or lease agreements entered into on or after July 1, 2005, and to any renewals, modifications, or extensions of such agreements in effect on such date.
