Evidence to review

• Separate detached residences from attached homes or planned-development properties before weighing sale prices.
• Examine whether a comparable has a corner site, an irregular parcel, or a materially different amount of usable land.
• Reconcile finished-basement information across listing material and county records so below-grade space is not mistaken for like above-grade area.
• Document deterioration with dated close-up and context photographs, then connect the condition to an estimate, inspection, or other specific record when available.

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