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
Today's $3,110/yr reflects a 10-year abatement. It jumps to about $31,109/yr in 2028 — $27,999/yr more. Price the full bill, not the current one.
If you own it
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
Renewal requires city tax clearance and zero open L&I violations on the property. A lapsed license suspends the right to collect rent or evict.
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 analyst below to dig into any number.

The abatement clock
This house pays about $3,110/yr under a 10-year tax abatement. In 2028 the bill reaches its full ~$31,109/yr — a step up of $27,999/yr, 1 assessment year out. Drag the slider.
now: ($2,222,400 assessed − $2,000,225 abated) × 1.3998% ≈ $3,110/yr
2028: $2,222,400 assessed × 1.3998% ≈ $31,109/yr
Flat 100% exemption (pre-2022 program, started 2018), 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.

City datasets are fetched live from OpenDataPhilly (phl.carto.com) and cached briefly. Dossiers re-pull automatically — on view once they're a few weeks old, plus a nightly rolling sweep — and citywide benchmarks recompute weekly; the masthead date is when this page's records were last pulled. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
