$0/year estimated property tax

2026 taxable assessment $0 × 1.3998%. This is an estimate, not a bill or account balance. The City maintains payments, credits, interest, and the current amount due.

OPA has published a 2027 assessment of $98,800. It is not the 2026 billed-year value.

Current City balanceCheck Tax Center

Payments, credits, interest, and the current amount due are maintained by the City.

Exemption classificationHomestead exemption

2026 OPA removes $91,000 from the taxable assessment through the owner-occupant exemption. The exclusion reduces this assessment-based estimate to $0.

Historical delinquency sources Record found

$39,372.95 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 1988–2014. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.

The snapshot’s 2022 context used $37,600 total assessment, $37,600 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.

A separate historical parcel ledger ending in 2016 records $36,147.51 and a lien entry. It is shown as historical context only.

Where this comes from

Methodology & freshness

This report was assembled Jul 28, 2026, 10:03 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.
