$1,144.89 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 $408.24 and a lien entry. It is shown as historical context only.

This report was assembled Jul 9, 2026, 7:12 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. “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.
