2026 taxable assessment $0 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $1,236,900; it is not the 2026 billed-year value.

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:
Property tax
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.
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 7751381102026 OPA shows a zero or de minimis taxable assessment. The open assessment split does not establish the exemption's legal basis, continuing eligibility, or treatment after a transfer.
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.”

Record summaryPhiladelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.

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 $1,236,900; it is not yet the billed-year tax basis.

Not a houseProperty report
This is a place of worship, not a home, and OPA shows a full or near-full assessment exemption whose basis must be verified. A $0 assessment-based tax estimate does not prove the live Tax Center account has no prior-period balance or other charges. Homeowner investment tools are hidden; the assembled public-source record remains below.

What this record suggests
The City file documents 5 permits touching roof work. 5 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
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.
"Built 1900" is usually a placeholder
Philadelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.

Methodology & freshness
This report was assembled Jul 11, 2026, 6:36 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.
