I live in Georgia. I did not have a lease agreement so my tenant is a tenant at will. They sent me an email on 9 Oct that they were moving. They paid rent from up thru 15 Nov (15 days of months rent). They actually vacated the property on 19 Oct leaving the house completely empty. I was fortunate enough to rent the house to another individual on 20 Oct. Now my previous tenants are wanting their rent back for the Nov payment. They say I got duplicate rent and should not have since they actually were still renting...even though they had no belongings in the house. Who is right??? Do I owe them the 15 days rent for Nov? Am I not entitled to 30 payment regardless of whether I rent the house out again or not???
