a. I go in the next day to inspect property. b. Are you saying you live in the same town and then didn't give the keys until Dec. 1? c. I don't rely on when they are supposed to move out I rely on when I go to the property and look to see they are moved out. d. I am wondering why when keys weren't returned on Nov 1 you didn't call up.
In my mind the legal date of vacancy is when it's available for rent.
