Historical tax record
Verify the current balance before relying on it.
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 $468 and a lien entry. It is shown as historical context only.

From the public recordWhat 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.
Public-record pressure
More than one 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 2024, 2025
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
Recent transition activity
The property has an unusually active paper trail worth monitoring for the next permit, inspection, deed, or listing.
Evidence: 6 permit events since 2023
Limit: Record activity alone does not establish that a sale or redevelopment is planned.
Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, 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
The tax bill is temporary
Today's $311/yr reflects a 10-year abatement. It steps up every year and reaches about $1,711/yr in 2033 — $1,400/yr more. Price the full bill, not the current one.
Built 1925: 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
When the abatement ends, file for Homestead
An abated home cannot also take the Homestead Exemption. From 2033 it can — knocking about $1,400/yr off the full bill.
$468 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.
Derived from this house's public records and the city's rules as of 2026 (abatement ordinance, Homestead, rental licensing, lead certification, L&I process, excavation protections). Informational only — not legal, tax, or investment advice.
The investment read
How this house 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.

The abatement clock
This house pays about $311/yr under a 10-year tax abatement that steps down every year. In 2033 the bill reaches its full ~$1,711/yr — a step up of $1,400/yr, 6 assessment years out. Drag the slider.
now: ($122,200 assessed − $99,983 abated) × 1.3998% ≈ $311/yr
2033: $122,200 assessed × 1.3998% ≈ $1,711/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2023) — reassessments move both lines. After expiry an owner-occupant can claim the Homestead Exemption (~$1,400/yr off); an abated home can't hold both.

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.
