After giving my 30 days notice on February 14th , my apartment owner sent me this : " Your 30 day notice will run to the end of March , not to the 14th , as the rental term is from the first of the month to the end of the month , that is the law . If you stay just one day into the next month , you owe for the entire month . After leaving and giving back all your keys , if there are no damages and the cleaning is done you will receive your security deposit money back . " Is this true ? Is he intentionally lying ? I so appreciate the clarification , thanks ! I'm trying to move before the 14th without penalty .
