A near-average overall index

BestPlaces gives Sebastian a cost-of-living score of 96.8, meaning total costs (housing, food, childcare, transportation, healthcare, taxes, and other necessities) run about 3.2% below the U.S. average and roughly 1% below the Florida state average. Monthly costs are estimated at $2,413 for a single adult and $5,313 for a family of four.

Housing runs below average; a few categories run slightly above

Housing costs in Sebastian run about 5% cheaper than the U.S. average per BestPlaces -- the main driver of the below-average overall index. Utilities run about 8% pricier and groceries about 5% pricier than the national average, a real, disclosed exception to the otherwise-affordable headline number.

No state income tax adds to the value proposition

Florida's lack of a state income tax stacks on top of Sebastian's already near-average cost index, a meaningful combination for retirees and fixed-income movers relocating from a state that taxes income. See the taxes-insurance topic for the city's specific property-tax and insurance figures.
