What stands out
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.
Recent 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 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 $0/yr reflects a 10-year abatement. It jumps to about $78,267/yr by 2026 — $78,267/yr more. Price the full bill, not the current one.
Zoned RSA2: one household by right
Single-family (semi-detached). Converting to a duplex or apartments needs a use variance the zoning board rarely grants — Pennsylvania courts require a physical hardship of the lot itself, and economics alone do not qualify.
The last transfer was not a sale
The most recent recorded deed moved for nominal consideration. That is where tangled-title problems live — budget a real title search. (Occupants untangling an inherited deed can get help from the city's Tangled Title Fund.)
If you own it
4 open violations: the clock matters
L&I appeals must be filed within 30 days — just 6 days if a property is designated UNSAFE or IMMINENTLY DANGEROUS. Left unresolved, the city can do the work itself, bill the owner (routinely $50,000+ on a rowhouse), lien the property, and add court fines of $300+/day.
If you’re the landlord
No active rental license on file
If this property is rented, Philadelphia requires a Rental License (via eCLIPSE) — without it a landlord cannot legally collect rent or evict, and tenants can withhold. Licensing needs tax clearance and no open violations.
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 $0/yr under a 10-year tax abatement. By 2026 the bill reaches its full ~$78,267/yr — a step up of $78,267/yr. Drag the slider.
now: ($5,591,300 assessed − $5,591,300 abated) × 1.3998% ≈ $0/yr
2026: $5,591,300 assessed × 1.3998% ≈ $78,267/yr
Flat 100% exemption (pre-2022 program, started 2016), then the cliff — 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.
