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 $3,453/yr reflects a 10-year abatement. It steps up every year and reaches about $14,242/yr in 2035 — $10,789/yr more. Price the full bill, not the current one.
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’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 $3,453/yr under a 10-year tax abatement that steps down every year. In 2035 the bill reaches its full ~$14,242/yr — a step up of $10,789/yr, 8 assessment years out. Drag the slider.
now: ($1,017,400 assessed − $770,722 abated) × 1.3998% ≈ $3,453/yr
2035: $1,017,400 assessed × 1.3998% ≈ $14,242/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2025) — 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.
