Enter a value, pick a town, and see the estimated annual bill — and the gap to a second town. Effective rate is the only figure that compares across the Cook/Lake county line.
Effective rate is tax as a share of market value — the only column that compares across the Cook/Lake county line. The last column applies each town's rate to that town's own median sale price, so it is a typical bill in that town, not a bill for your house. That median counts single-family houses only, across roughly the last twelve months, so it excludes condos and townhouses. It also pairs a 2026 price with a tax-year-2024 rate, which makes the last column a ceiling rather than a quote.
