Pricing
from $0.03 / 1,000 illinois property transfer declaration records
Every Illinois real-estate transfer declaration filed with the State (public open data, 2.93M deeds, 2014-today): address, parcel index number, instrument type, consideration paid, transfer tax split State vs. county, and the named buyer and seller. Filter by county, buyer, seller, parcel or amount.
Substring match on the county where the property sits, e.g. 'Cook' (1.44M of the 2.93M), 'DuPage', 'Lake', 'Will'. 102 counties in total. Blank = any.
Substring match on the named buyer as written on the declaration. Blank = any.
Substring match on the named seller as written on the declaration. Blank = any.
Substring match on the Property Index Number, e.g. '12-07-426-034'. Use it to pull the transfer history of one parcel. Blank = any.
Substring match on the property's full address as recorded, e.g. 'ROCKFORD', 'LA SALLE'. Blank = any.
Substring match on the city on the declaration. Blank = any.
Substring match on the property ZIP, e.g. '61101'. Blank = any.
Substring match on the township. 1,570 distinct values - too fine-grained to aggregate over, so it is a filter only. Blank = any.
Exact instrument, matched exactly and never as a substring - 'Warranty Deed' and 'Special Warranty Deed' are separate instruments. Warranty deeds are 1.84M of the 2.93M, trustee deeds 286K, special warranty deeds 213K. 'Other' is the filer's own word. Blank = any; 409,739 declarations (14%) named no instrument and come back only when this is left blank.
The single letter the filer entered for current use, exactly as the State publishes it. The source ships no legend for these codes, so no label is attached here. 'B' is by far the most common (2.12M). Blank = any; 392,991 declarations left it blank.
Substring match on the State's declaration identifier for a single-record lookup. Blank = any.
Substring match on the county recorder's document number. Blank = any.
Earliest recording date, YYYY-MM-DD. The recording date is complete and free of sentinels across all 2.93M rows, so it is the reliable axis. Blank = any.
Smallest stated full consideration in dollars. Note that 331,437 transfers state $0 - a nominal or unstated price, mostly corrective and intra-family deeds. Set 1 to exclude them. Blank = no lower bound.
Largest stated full consideration in dollars. Blank = no upper bound.
Only declarations recorded within the last N days. Ignored when 'Recorded from' is set. 0 = off.
rows = declarations matching your filters (default). aggregate = one count row per group (see groupBy).
Which dimension to aggregate over (mode=aggregate). Blank = county. Every group is returned - aggregate mode is not cut off by maxResults. Township is deliberately absent: 1,570 values is a raw geography, not a rollup.
