Property summary
What the record is signaling
Early patterns mined across this property's dated public records. Each flag shows what triggered it and where the inference stops.
The assessment jumped 136% in 2027, but no matching permit appears in the property timeline.
Evidence: assessment moved from $540,000 to $1,274,200 · no permit shown in 2026-2028
Limit: Not proof of unpermitted work; reassessment, corrected data, or a permit under another parcel can also explain it.
Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, not a prediction or allegation.
This is a apartment building, not a home, and it pays no property tax. BlockReport's value, tax and investment tools are for residential parcels, so they're hidden here. The full public record is still below, and the analyst can answer anything about it.

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.
