$980/year estimated property tax

2026 taxable assessment $70,000 × 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 $800,000. 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.

2026 taxable assessment equals the full assessed value.

Historical delinquency sources Record found

$13,986.47 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2017–2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.

5years recorded 2017–2021tax periods Yesactionable flag Nopayment agreement Nobankruptcy flag Noassessment appeal

The snapshot’s 2022 context used $168,000 total assessment, $168,000 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.”

Where the record looks off

Conflicts in City paperwork. Flags on the data, not the property.

Assessment and sale price disagree hard

Assessed at $800K, but it traded for $79,181 in 2024 — a 10.1× 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. Events are deduped by parcel, business identity, and license type, so a renewal is not shown as another opening. Other permit and filing types remain in the full source ledger.

Where this comes from

Methodology & freshness

This report was assembled Jul 24, 2026, 6:26 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.
