Winnebago County, Illinois
Explore accurate parcel and ownership records,
directly sourced from county assessors.
Recorded property characteristics and residential parcel-sale records for Winnebago County, 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.
