Atlanta has state income tax, while Florida doesn't. Property taxes tend to be higher in some parts of Georgia, but this impacts homeowners more directly. For renting, Orlando and Atlanta are pretty close these days in many neighborhoods. You'll probably pay slightly more for rent in a desirable Atlanta area. Transportation costs might be a bit lower in Orlando depending on where you live and work, as it can be easier to get around without a car in some areas. Run a detailed after-tax calculation considering these factors.
