Where the record looks off
Conflicts in City paperwork. Flags on the data, not the property.
Assessment and sale price disagree hard
Assessed at $48K, but it traded for $132,500 in 2024 — a 2.8× gap. Could be a non-market deed the record doesn't label, or an assessment that hasn't caught up.

A license is an L&I registration, not proof that a business is open, operating today, or located at this storefront. Dates are license dates.

Methodology & freshness
This report was assembled Jul 23, 2026, 12:26 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.
