Property summary
Historical tax record
Verify the current balance before relying on it.
$6K 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 $4K and a lien entry. It is shown as historical context only.

Early patterns mined across this property's dated public records. Each flag shows what triggered it and where the inference stops.
More than one public record deserves a current-status check.
Evidence: $6,030 appeared in the City's June 2022 delinquency snapshot · a lien number appears in the historical tax ledger through 2016
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
The assessment jumped 1082% in 2023, but no matching permit appears in the property timeline.
Evidence: assessment moved from $14,200 to $167,900 · no permit shown in 2022-2024
Limit: Not proof of unpermitted work; reassessment, corrected data, or a permit under another parcel can also explain it.
Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, 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.

Methodology & freshness
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.
