Learn moreA real, genuine housing-affordability advantage
Zillow's average home value for Ottawa is $214,364, up 6.6% year-over-year -- meaningfully below the national median. Redfin's March 2026 median SALE price ($250,000) and Movoto's July 2026 median LIST price ($367,000) show a real, disclosed spread this record states rather than reconciles.
A real, disclosed modest income dip
Ottawa's median household income was $71,413 in 2024, a real, disclosed decline from the prior year's $73,011 -- a modest, worth-noting dip this record does not omit.
Illinois's statewide flat income tax applies fully
Illinois's simple, flat 4.95% state income tax on wages applies in Ottawa as anywhere else in the state -- though Illinois exempts ALL retirement income (Social Security, pensions, 401(k)/IRA distributions) with no age or income threshold, a real, substantial positive directly relevant to Ottawa's own genuinely older, retiree-oriented population (see the retiring topic page).
A real, moderate combined sales tax
Ottawa's combined sales tax rate is most consistently cited at 7.0% (6.25% Illinois state + 0.25% LaSalle County + 0.50% city local), though one 2026 citation shows a higher 7.5% rate -- a real, disclosed spread worth confirming directly via Illinois's MyTax rate finder before a time-sensitive purchase.
