Question or correct this record

BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:

The estimate, live balance, and back-tax record are different.

BlockReport can calculate the annual tax from the City’s taxable assessment. Payments, credits, interest, and a current amount due live separately in Philadelphia Tax Center.

Estimated annual Real Estate Tax$7,223/year

2026 taxable assessment $516,000 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $346,000; it is not the 2026 billed-year value.

Official current account balanceCheck live

A Tax Center balance is net of bills, payments, credits, interest, and adjustments. A credit—or an amount due—is not automatically “back taxes.”

OPA 881001182
Open Philadelphia Tax Center →Choose “View period balance” to see the tax year and any credit, interest, or delinquency.
Exemption classificationNo exemption shown

2026 taxable assessment equals the full assessed value.

Historical delinquency sources No current conclusion

The June 2022 delinquency snapshot was not verifiably available in this cached report. No conclusion about a match—or today’s balance—can be drawn from that absence.

For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”

Finding

Marked sealed, but it just sold

Record summary

The assessor's condition code says sealed, yet a $590,000 sale was recorded in 2025. One side of the record is stale — condition codes come from drive-by field visits that can lag years behind.

The property record, over time

Every dated deed, permit, inspection, license, violation, certification, and appeal is placed on the City’s annual assessment line. Select a point to read what happened; the line is an assessment history—not a sale-price chart or appraisal. OPA has also published a 2027 assessment of $346,000; it is not yet the billed-year tax basis.

What this record suggests

5 violations are still marked open in the assembled record. The date and status belong in a current L&I check before relying on them.

Where the record looks off

Places where the city's own paperwork disagrees with itself. These are flags on the data — not problems with the property.

Marked sealed, but it just sold

The assessor's condition code says sealed, yet a $590,000 sale was recorded in 2025. One side of the record is stale — condition codes come from drive-by field visits that can lag years behind.

Where this comes from
Methodology & freshness

This report was assembled Jul 9, 2026, 12:29 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.
