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: 9 open L&I violations · failed L&I inspection activity in 2025

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: 8 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.

Methodology & freshness

Available City datasets are queried from OpenDataPhilly (phl.carto.com), then reports are cached and refreshed on a rolling schedule. Source dates vary: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. Other dossiers re-pull on view once stale, and citywide benchmarks recompute weekly. AI-written passages are generated from these records only and rejected if they state a number the record doesn't 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.
