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$4,717/year

2026 taxable assessment $337,000 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $312,600; 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.”

Exemption classificationNo exemption shown

2026 taxable assessment equals the full assessed value.

Historical delinquency sources Record found

$23,949.31 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2015–2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.

The snapshot’s 2022 context used $183,800 total assessment, $183,800 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.

A separate historical parcel ledger ending in 2016 records $4,512.44 and a lien entry. It is shown as historical context only.

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 1920: 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.

If you own it

$4,512 in the historical tax ledger through 2016

Historical context only, not a current payoff figure; that ledger also contains a lien entry. Verify today's balance and lien status directly with Philadelphia Revenue before relying on it.

If you’re the landlord

If it is rented, verify the Rental License

The fetched license records do not show an active Rental License. Ownership type or a tax mailing address does not prove that tenants occupy the property; if it is rented, verify the current license and legal occupancy in eCLIPSE.

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.

Assessment and tax history

What this record suggests

The City file documents 6 permits touching kitchen work, electrical work, plumbing. 6 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.

Flags: $24K recorded in the June 2022 delinquency snapshot — verify current balance · historical tax ledger through 2016 recorded $5K with a lien entry. Informational only — not investment advice or a consumer report (FCRA).

Methodology & freshness

This report was assembled Jul 11, 2026, 1:30 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.
