Recent home sales in West Chicago Township
From July 13, 2024 through July 13, 2026, the comparison pool contains 4,777 recorded single-family sales.
- Median sale price: $449,000
- Median sale price per square foot: $214
- Median building size: 2,200 square feet
These are recorded single-family sales used as comparison evidence, not an estimate of any home's value.
Evidence to review
- Read the Assessor's description closely for classification, residential type, square footage, age, and other building details that may need correction.
- Build separate comparison sets for condominiums, single-family houses, and two- to six-flats so unlike property types do not blur the analysis.
- Check recent recorded sales in the same assessment neighborhood and retain the records that most closely match the subject's physical traits.
- Organize dated photos by condition issue and supplement them with permits, estimates, or inspection material when those records add context.
