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 $3,614/yr reflects a 10-year abatement. It steps up every year and reaches about $12,147/yr in 2036 — $8,533/yr more. Price the full bill, not the current one.
Federal law requires a lead-paint disclosure at sale for any pre-1978 home. If it will be rented, Philadelphia also requires a lead-safe or lead-free certificate before a rental license can issue.
The most recent recorded deed moved for nominal consideration, within one family. 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
Built 1930: every rental unit needs a lead-safe or lead-free certificate on file with the City. Without one: fines up to $2,000/day per unit, tenants may withhold rent, courts can order rent refunded — and no eviction will stand.
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 $3,614/yr under a 10-year tax abatement that steps down every year. In 2036 the bill reaches its full ~$12,147/yr — a step up of $8,533/yr, 9 assessment years out. Drag the slider.
now: ($867,800 assessed − $609,620 abated) × 1.3998% ≈ $3,614/yr
2036: $867,800 assessed × 1.3998% ≈ $12,147/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.
