Historical tax record
Verify the current balance before relying on it.
$567 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 $266 and a lien entry. It is shown as historical context only.

From the public recordAssessment and sale price disagree hard
Why it mattersAssessed at $29K, but it traded for $121,001 in 2026 — a 4.1× gap. Could be a non-market deed the record doesn't label, or an assessment that hasn't caught up.
View supporting records →What the record is signaling
Early patterns mined across this property's dated public records. Each flag shows what triggered it and where the inference stops.
Public-record pressure
More than one public record deserves a current-status check.
Evidence: $567 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 2023
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, not a prediction or allegation.
Vacant landLand report
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.
