Area property statistics

Recorded property characteristics and residential parcel-sale records for Ottawa, IL. Sale amounts describe recorded transfers, not asking prices or appraisals. Each measure uses records with that information available.

Sale records use the AVM's residential, amount, floor-area, year-built, price-per-area, deed, buyer-relationship and distress filters. Known multi-parcel deals are also excluded. Unknown package flags are not proof of a single-parcel sale. Counts represent eligible parcel sale records. Recorded annual averages require at least 10 eligible sales. Projections must have enough history and pass checks against earlier recorded sales. Recent sales can be underreported; different coverage between years can affect the changes.

City measurements cover the selected county's portion of the city.

Annual sales comparison

Calendar 2025 recorded sales versus calendar 2026 model projections. Both years cover January 1–December 31. Change compares the 2026 projection with the recorded 2025 value. Annual average amounts weight each month by its sales count; they are not monthly medians.

Other recent-period estimates

These use different periods from the calendar-year comparison. Estimates extend parcel-record counts and recorded amounts; they are not confirmed current transactions or individual-property values.

No supported recent-period estimates are available for this area. Recorded statistics above remain available.

Transaction coverage has not been verified. Known multi-parcel deals are excluded; missing package flags do not establish that every remaining sale covers one parcel. Amount change compares monthly record medians, not the appreciation of the same homes. Ranges reflect historical model errors; they are not confidence intervals and can exclude the point estimate.
