Tax delinquent properties

One whose owner missed the property tax deadline. The county keeps a list, and the list is public: in most states it is published once a year and kept current on the treasurer's or tax collector's site. A parcel on it is not for sale. The owner can still pay, and most do, often years before the county may sell.

From each county's own published roll or parcel data: the tax collectors' unpaid real-estate reports in Miami-Dade, Broward, Hillsborough, Orange and Duval counties, Florida; the tax office's delinquent file in Travis, Collin and Denton counties in Texas; the fiscal office, auditor and treasurer rolls of Summit, Hamilton, Montgomery and Clermont counties and the City of Youngstown in Ohio; Wake and Guilford counties' bill extracts in North Carolina; the treasurers' files of Norfolk and Virginia Beach; the District of Columbia's tax roll extract; Sonoma County's defaulted-tax data in California; and the Hennepin and St. Louis county parcel layers in Minnesota. We read each one daily and keep what it says, parcel by parcel.

Every source is the county's complete current list, so a parcel that drops off it has been paid, transferred or sold. We mark it cleared the day it vanishes and keep the record, so a list you work from here is as current as the county's own, and you can see how many cleared in the last 30 days.

The owner of record and the mailing address on every record, the record page, and an export. The county, the property address, the amount owed, the years and the stage are public on every page.
