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.

Estimated annual Real Estate Tax$1,575/year

2026 taxable assessment $112,500 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $124,500; 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.”

Exemption classificationNo exemption shown

2026 taxable assessment equals the full assessed value.

Historical delinquency sources Record found

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

A separate historical parcel ledger ending in 2016 records $318.85 and a lien entry. It is shown as historical context only.

2016$318.85 total · $201.29 principal · $7.68 interest · $5.13 penalty

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

Legal due diligence

What this record proves—and what it does not.

These checks are triggered by this property’s actual City rows. They identify the controlling document to verify; they do not declare a use legal, a building safe, or title clear.

1 verify 1 favorable dated record

VerifyFailed inspections are dated events—not the current condition14 failed, 6 passed, and 4 CLOSED investigation outcomes are in the fetched history; the latest dated visit was PASSED on Mar 22, 2023.

Why it mattersA PASSED or FAILED value applies to that inspection visit. CLOSED is a separate source status; none of the three alone proves the parent permit or violation case closed—or describes today’s condition.

Verify nextOpen the parent case/permit for each material failure and confirm its later disposition.

Open the controlling City guidance ↗

Favorable dated recordNo open violation; closed history remains relevantThe fetched record shows 0 open and 19 historical violations across 7 cases.

Why it mattersA closed case is materially better than an open one, but it does not by itself prove that every altered use, unit, or concealed condition matches today’s approvals.

Verify nextUse the closed cases to target the inspection and occupancy-file review.

Open the controlling City guidance ↗

Closing file: checks no public-record summary can replace3 documents/searches to assign before settlement

Property Sales Certification

The seller must obtain Philadelphia’s certificate showing the base zoning, last use in the zoning record, and open violations. The City warns that it does not prove Building Code occupancy or show zoning overlays.

Next: Obtain the fresh certificate and compare it with the CO, permits, and Atlas overlays.

Official guidance ↗

Date-effective City Property Payoff

The Tax Center Property Payoff covers Real Estate Tax, Commercial Trash, and L&I abatement-work invoices. Philadelphia says it does not include business-tax debts or liens, water and sewer charges, or fines for code violations.

Next: Request the City statement effective through settlement; read every period and invoice.

Official guidance ↗

Professional title and water-lien searches

OPA ownership, deed summaries, and a zero tax balance are not clear title. Mortgages, judgments, municipal claims, water liens, easements, heirs, and other encumbrances require separate searches.

Next: Use a Pennsylvania lawyer/title company and obtain owner’s title insurance; order the separate water search/payoff.

Official guidance ↗Separate water-lien guidance ↗

Informational only—not a legal opinion, title report, code inspection, tax payoff, or substitute for a Pennsylvania lawyer, title company, inspector, or tax professional.

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

More than one separately dated public record deserves a current-status check.

Evidence: a lien number appears in the historical tax ledger through 2016 · failed L&I inspection activity in 2023

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

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

Not a houseProperty report

This is a house, not a home. 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.

Methodology & freshness

This report was assembled Jul 10, 2026, 5:20 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.

About this data & fine print

Answers are generated by an AI agent querying available City of Philadelphia open data at the moment you ask: OPA property assessments, Recorder of Deeds transfer records, L&I permits, violations & licenses, dated Dept. of Revenue tax records, Zoning Board appeals, Police incident reports, Philly311 requests, and School District of Philadelphia catchment and school data.

For an explicit web search or a current listing/news question, the agent may also search the public web through OpenRouter and must link every web-derived claim. Public listing pages can be stale and are not direct or comprehensive MLS access.

Property-level tax data is historical: the delinquency snapshot is dated June 2022 and the separate detailed ledger ends in 2016. Neither shows what is owed today; verify a current balance with Philadelphia Revenue.

City data is published as-is and can lag, contain errors, or be corrected later; school performance datasets run years behind and are labeled with their school year. AI answers can contain mistakes — verify anything that matters against the official record (property.phila.gov, atlas.phila.gov) before acting on it.

Informational only. Not legal, financial, or investment advice. Not a consumer report under the FCRA — it may not be used to decide anyone's eligibility for housing, tenancy, employment, credit, or insurance.
