What you can do with Cook County owner data
Pull every absentee owner in a zip code and export the mailing addresses for a direct-mail campaign. Draw a box around a subdivision on the map and skip-trace the whole block in one click. Look up who owns the lot next to a listing, then call them with a verified number instead of a letter that gets thrown away.
Where the data comes from
Parcel boundaries, owner of record and mailing addresses are public records maintained by the county assessor or GIS office. Quarry pulls them directly from the county's own published services and refreshes on the county's cycle. Phone and email come from the skip-trace engine, cross-checked across sources and scored, and you are only charged when a contact is found.
