Florida has no state income tax, which is attractive, but factor in higher property taxes and potentially higher homeowner's insurance, especially near the coast due to hurricane risk. Texas has property taxes that can be quite high depending on the specific location, but no state income tax. Cost of living can vary wildly within both states, so drill down to the specific cities you're considering. Look at groceries, transportation, and entertainment costs for a detailed comparison. Also, sales tax in Texas is higher (6.25% state + local) vs Florida (6% state + local).
