How these numbers are made

Property tax uses Cook County's 2025 agency rates for tax code 13031 (Village of Posen, School District 143 1/2, Community High School District 228, South Suburban College, Posen Park and Library districts, Bremen Township; total 12.036861 per $100 of equalized assessed value), the code that covers most Posen parcels in the county rate file. Starting value is the Assessor's Bremen Township 2023 median ($199K) at 10% times the 2025 factor 3.03.
Water is the village's 2026 rate of $12.92 per 1,000 gallons with a 3,000-gallon minimum ($38.76) and sewer $1.70 per 1,000 gallons with a $5.10 minimum, both stated as unchanged since 2018. The village notes a minimal meter-maintenance charge and, in some areas, a lift-station charge; neither amount is published, so they are not included.
Garbage is the $29.25 per household unit rate starting October 2026, entered as a monthly charge on the monthly water bill. Electricity is ComEd delivery plus the October 2026 price to compare; gas is Nicor Rate 1 with the October 2026 supply cost of 33 cents per therm plus the $0.35 Posen franchise cost adjustment.
Typical use is the Illinois average residential use from EIA. Not included: homeowners insurance.
