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$5,920/year

2026 taxable assessment $422,900 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $402,700; 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 472121000
Open Philadelphia Tax Center →Choose “View period balance” to see the tax year and any credit, interest, or delinquency.
Exemption classificationHomestead exemption

2026 OPA removes $100,000 from the taxable assessment through the owner-occupant exemption.

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.”

What to do with this

The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.

If you’re buying

Built 1915: lead rules apply

Federal law requires a lead-paint disclosure at sale for any pre-1978 home. If it will be rented, Philadelphia also requires a lead-safe or lead-free certificate before a rental license can issue.

Multiple units and RSA5 zoning need reconciliation

The assessment or license record describes multiple units while the zoning district is generally single-family. That does not establish whether the use is lawful, nonconforming, abandoned, or incorrectly coded. Verify the registered use and Certificate of Occupancy with L&I before pricing multiple rents.

Derived from the fetched property records and linked City guidance as of 2026. Assessment treatment is not a substitute for an exemption approval, live balance, title report, license, occupancy certificate, or inspection. Informational only — not legal, tax, or investment advice.

Methodology & freshness

This report was assembled Jul 11, 2026, 7:32 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.
