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$123,195/year

2026 taxable assessment $8,800,900 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $8,225,900; 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.”

2026 taxable assessment equals the full assessed value.

Historical delinquency sources Record found

$327,148.61 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.

A separate historical parcel ledger ending in 2016 records $29,510.07 and a lien entry. It is shown as historical context only.

2016$29,510.07 total · $27,076.09 principal · $406.14 interest · $270.76 penalty

Records to verify together

Rule-based groupings across this property's dated public records. Each flag shows the records that belong in the same verification step and where the inference stops.

Dated record flagRecords to verify together

Several independent, separately dated records stack up here and deserve prompt verification.

Evidence: 12 open L&I violations · $327,149 appeared in the City's June 2022 delinquency snapshot · a lien number appears in the historical tax ledger through 2016 · failed L&I inspection activity in 2022, 2023, 2025, 2026

Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.

Dated record flagRecent transition activity

The property has an unusually active paper trail worth monitoring for the next permit, inspection, deed, or listing.

Evidence: 4 permit events since 2023

Limit: Record activity alone does not establish that a sale or redevelopment is planned.

Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, not a prediction or allegation.

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

12 open violations: the clock matters

Most L&I appeals must be filed within 30 days; unsafe or imminently dangerous orders can carry a shorter deadline. Unresolved notices can lead to fees, court enforcement, City abatement work, and liens. Read the dated notice and verify its current status with L&I.

$29,510 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.

The investment read

How this building has moved and where it's pointed: the city's assessed value (not a listing price) over 12 years, charted against its block; appreciation is that history's pace, and the 5-year figure simply extends it. Yield estimates rent-vs-price from area rents. Ask the record to dig into any number.

Where this comes from

Methodology & freshness

This report was assembled Jul 9, 2026, 2:31 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.
