A real, substantial housing-affordability advantage

Belleville's median home value runs approximately $141,300-$158,463 depending on source -- well below Illinois's statewide average ($294,136) and the national median, a real, substantial affordability advantage.

A real, notable property-tax nuance

Belleville's own median effective property tax rate (2.55%) runs meaningfully HIGHER than St. Clair County's own broader average (2.03%) -- Belleville itself is a comparatively high-tax pocket within its county, even though the resulting dollar bill stays modest given the city's low home values.

A real, disclosed income gap relative to the St. Louis metro

Belleville's median household income ($63,535) ran roughly 80% of the broader St. Louis metro's own figure ($80,196) -- a real, disclosed gap worth factoring into a relocation budget.

Illinois's statewide income tax structure applies identically

Illinois's real, flat 4.95% income tax on wages, and its full exemption of Social Security, pension, and 401(k)/IRA income, apply the same in Belleville as anywhere else in the state -- see illinois.js.
