Arizona's median homeowner pays $1,894 on a $427,600 home — 0.44% effective (ACS 2025). Nominal rates mislead across states (assessment ratios differ); the effective rate is the honest comparator. Your parcel's bill follows its own assessment and the overlapping local levies.

Limited Property Value (Prop. 117; A.R.S. s.42-13301): LPV = prior-year LPV + 5% maximum, and may not exceed full cash value; LPV (not market value) is the tax base, and residential property is then assessed at a 10% ratio.

This family is the pilot the plan called for: all 51 state pages plus the 25 most populous counties — not thousands of county pages with rates nobody verified. County figures here are the same ACS medians at county level.
County assessors publish parcel-level figures.
Assessments lag markets, exemptions differ (senior, veteran, disability), and local levies stack differently street by street. The effective-rate model gives the typical bill for the value, not your parcel's bill.
By effective rate, Illinois (1.92%) and New Jersey (1.82%); by median dollars, high-value states like New Jersey ($9,648) and California ($5,537) — the hub table shows both lenses.
