D.N.
When we rented, we moved on the 1st of the month in the morning, and new tenant moved in in the afternoon. They moved out of their old apartment in the morning. We have had tenants and the same thing, they moved the 1st and new one moved in on the 1st. If we had to do repairs or anything (always walked through when they tenant first told us they were moving), we made the new tenant move in date later so we had time to repaint or fix.
