How these numbers are made

Property tax uses the LaSalle County Clerk's 2025 primary lump rate of 8.67329 per $100 for Mendota; the county notes lump rates may vary by property location and are based on what the majority pay. The component districts are not itemised here.
Starting value is the average residential assessed value in the City of Mendota taxing district (117,386,320 over 2,318 parcels); the $6,000 general homestead exemption comes off it.
Water is $20.00 plus $3.11 per 100 cubic feet and sewer is $14.00 plus $5.80 per 100 cubic feet, from the city water and sewer page (no effective date shown). The city publishes no typical use, so the page uses its default.
Trash is $17.15 a month on the city water bill. Electric and gas use the ComEd and Nicor Rate 1 figures as in the nearby ComEd/Nicor models, with Illinois average use.
Gas per therm = 24.44¢ distribution + 33¢ October 2026 supply + Rider 12 (0.47¢) + Rider 30 (0.98¢) + Rider 38 (1.43¢) + Rider 3 (-0.05¢) = 60.27¢; fixed $21.30 + Rider 26 (-$0.11). Nicor Rider 1 customer-charge adjustment and any municipal gas tax were not found.
Electric: ComEd delivery fixed and per-kWh charges plus the 10.103¢ Price to Compare (supply and transmission); the ratebook did not let us confirm every small rider or a franchise-fee line.
No Mendota municipal electric or gas utility tax was found in the city's published code (ecode360 Chapter 270 did not load its text), so none is shown.
Insurance is the Illinois state average for 2022 (newest NAIC figure via Triple-I) and is not Mendota-specific; newer non-NAIC surveys (S&P RateWatch 2023 $3,044, CFA 2024 $2,942) are higher, so this is probably low.
Nothing here is legal, tax or insurance advice.
