Housing and Rent Run Genuinely More Affordable Than the Illinois Statewide Average

As detailed on the housing-market and renting topic pages, Springfield's Zillow average home value ($163,198) runs roughly 44.5% below Illinois's own statewide average ($294,136), and Springfield's rent ($1,100-$1,270 depending on source) runs meaningfully below typical national average apartment rent figures -- a real, core part of Springfield's relocation affordability appeal.

Illinois's Real, Simple Flat State Income Tax, With a Real Retirement-Income Exemption

As detailed on the taxes topic page, Illinois's real, simple flat 4.95% state income tax rate is genuinely low and easy to plan around, and Illinois does NOT tax Social Security, pensions, or 401(k)/IRA distributions -- a real, substantial cost-of-living advantage for retirees specifically that applies fully in Springfield.

A Real, Disclosed High Property Tax and Sales Tax Burden

As detailed on the property-taxes and taxes topic pages, Sangamon County's own median effective property tax rate runs a real, disclosed 2.28% -- more than double the national median -- and Springfield's combined sales tax runs 9.75% (6.25% state + 1% county + 2.5% city). Neither should be assumed away by Springfield's affordable housing headline alone.

A Real, Disclosed Median-Income and Poverty-Rate Context

Springfield's median household income runs $66,064, with a real, disclosed poverty rate of 16.83% -- meaningfully above both the 12.5% national and 11.8% Illinois statewide poverty rates. This record discloses this honestly as a real economic headwind alongside Springfield's own affordability metrics, rather than presenting affordability in isolation from local income context.
