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 $1,078/yr reflects a 10-year abatement. It steps up every year and reaches about $5,392/yr in 2034 — $4,314/yr more. Price the full bill, not the current one.
If you own it
Interest and penalties keep compounding until a Revenue payment agreement is in place, and a lien is already filed — an owner-occupant agreement also stops the sheriff-sale track.
If you’re the landlord
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 analyst below to dig into any number.

The abatement clock
This house pays about $1,078/yr under a 10-year tax abatement that steps down every year. In 2034 the bill reaches its full ~$5,392/yr — a step up of $4,314/yr, 7 assessment years out. Drag the slider.
now: ($385,200 assessed − $308,189 abated) × 1.3998% ≈ $1,078/yr
2034: $385,200 assessed × 1.3998% ≈ $5,392/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2024) — 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.
