Methodology & Assumptions

State income tax shown is the top marginal rate from the Tax Foundation[1] and state DOR publications[3]. Effective rate on median income differs; the "effective tax burden" metric in the comparison table approximates income tax as (top marginal / 2) + property tax rate.

Property tax rate is the effective rate (taxes paid as % of owner-occupied home value)[1]. Actual millage rates vary by county and city; these are statewide averages.

Median home price is the Zillow Home Value Index (ZHVI) statewide typical home value[2].

Cost of Living Index is the BEA Regional Price Parity[4] normalized so 100 = national average.

Homeowners insurance averages are NAIC HO-3 annual premiums[5].

Macro figures (unemployment, real median household income) come from FRED[6] and the Census ACS[7].

"Who wins by group" (retirees, families, high earners, remote workers) is a simplified decision framework; personal circumstances vary.
