The township was reassessed with the City Triad for 2024, its next reassessment is scheduled for 2027, and its Board of Review window opens annually.
Recent home sales in North Chicago Township
From July 13, 2024 through July 13, 2026, the comparison pool contains 503 recorded single-family sales.
- Median sale price: $1,620,189
- Median sale price per square foot: $577
- Median building size: 2,997 square feet
These are recorded single-family sales used as comparison evidence, not an estimate of any home's value.
Evidence to review
- Confirm that every record used as evidence belongs to Cook County's North Chicago Township, not the separate municipality in Lake County.
- Review the Assessor's class, construction details, building size, and unit count for both the subject and each proposed comparable.
- Do not compare a condominium with a single-family or multi-unit property; select the same residential form and similar attributes.
- Use recent recorded sales from the same assessment neighborhood and note any transaction or property difference that affects comparability.
- Document visible deterioration or unfinished work with dated photographs and related repair records when available.
