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 $1,847/yr reflects a 10-year abatement. It steps up every year and reaches about $5,893/yr in 2036 — $4,046/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
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 $1,847/yr under a 10-year tax abatement that steps down every year. In 2036 the bill reaches its full ~$5,893/yr — a step up of $4,046/yr, 9 assessment years out. Drag the slider.
now: ($421,000 assessed − $289,053 abated) × 1.3998% ≈ $1,847/yr
2036: $421,000 assessed × 1.3998% ≈ $5,893/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2026) — 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.
