Historical delinquency sources Record found
$369.60 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 $1,091,900 total assessment, $1,091,900 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.
For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”

Methodology & freshness
This report was assembled Jul 29, 2026, 6:57 AM 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.
