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$6,649/year

2026 taxable assessment $475,000 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $713,500; 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 881131220
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

This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

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

Assessment and sale price disagree hard

Why it matters

Assessed at $714K, but it traded for $2,300,000 in 2025 — a 3.2× gap. Could be a non-market deed the record doesn't label, or an assessment that hasn't caught up.

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 $713,500; it is not yet the billed-year tax basis.

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.

Assessment and sale price disagree hard

Assessed at $714K, but it traded for $2,300,000 in 2025 — a 3.2× gap. Could be a non-market deed the record doesn't label, or an assessment that hasn't caught up.

Where this comes from
Methodology & freshness

This report was assembled Jul 10, 2026, 12:58 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.
