Historical delinquency sources Record found
$137.77 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.

The snapshot’s 2022 context used $62,600 total assessment, $62,600 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.

Where the record looks off
Conflicts in City paperwork. Flags on the data, not the property.
Assessment and sale price disagree hard
Assessed at $188K, but it traded for $1,397,500 in 2024 — a 7.4× gap. Could be a non-market deed the record doesn't label, or an assessment that hasn't caught up.

Methodology & freshness
This report was assembled Jul 29, 2026, 4:03 PM ET. Available City datasets are queried from OpenDataPhilly (phl.carto.com) and the cited City ArcGIS feeds; record queries paginate rather than silently taking a first page. For this property: Permits: queried · Violations: queried · Investigations: queried · Appeals: queried · Licenses: queried · Building certifications: queried. “Unavailable” means the source query failed or was not supplied, not “no record.” Reports re-pull on view after seven days and on an overnight rolling schedule; citywide benchmarks recompute weekly. Source dates still govern: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. The live balance and date-effective payoff must be verified in Tax Center. AI-written passages are grounded in the assembled record and rejected if they state a number the record does not hold.
