Methodology & Assumptions

Home prices use Zillow Home Value Index (ZHVI)[1]; rents use Zillow Observed Rent Index (ZORI)[1]. Median household income comes from the Census ACS 5-year estimates[2].

COL indices use the BEA Regional Price Parity methodology[3], normalized so 100 = national average.

Property tax rates are effective rates from the Tax Foundation[4], expressed as % of owner-occupied home value. Mortgage estimates assume 6.5% fixed rate[5], 30-year term, 20.0% down, $1,800/yr homeowners insurance.

Federal tax calculations[6] assume single filer, standard deduction. State tax uses the top marginal rate times taxable income after the state standard deduction. FICA = 6.2% Social Security (up to wage base) + 1.45% Medicare.

Salary equivalence uses adjusted = salary × (COL_destination / COL_origin). This captures cost-of-living shift but not state income tax differences.

Unemployment figures are the most recent monthly MSA-level readings from the BLS LAUS series[7].
