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.

To check property facts on the county map, follow our CookViewer property comparison walkthrough. Keep assessment values separate from recorded sale prices.
