BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:

Historical tax record
$22K was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.
A separate historical parcel ledger ending in 2016 records $9K and a lien entry. It is shown as historical context only.

More than one separately dated public record deserves a current-status check.
Evidence: $21,552 appeared in the City's June 2022 delinquency snapshot · a lien number appears in the historical tax ledger through 2016 · failed L&I inspection activity in 2021, 2022
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
The property has an unusually active paper trail worth monitoring for the next permit, inspection, deed, or listing.
Evidence: 2 permit events since 2023 · demolition activity since 2023
Limit: Record activity alone does not establish that a sale or redevelopment is planned.
Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, not a prediction or allegation.
An empty lot: no building, just the land and its paper trail. The homeowner tools don't apply; the deed history, owner and zoning are below, and the analyst can trace what the owner holds citywide.

Available City datasets are queried from OpenDataPhilly (phl.carto.com), then reports are cached and refreshed on a rolling schedule. Source dates vary: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. Other dossiers re-pull on view once stale, and citywide benchmarks recompute weekly. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
