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 $514/yr reflects a 10-year abatement. It jumps to about $2,476/yr in 2029 — $1,962/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.
Single-family rowhouse (the classic Philly row). Converting to a duplex or apartments needs a use variance the zoning board rarely grants — Pennsylvania courts require a physical hardship of the lot itself, and economics alone do not qualify.
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
Built 1915: 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.
Value vs. the block, over time — sales, permits & L&I events marked on the line
Bought for $12K in 2017, built new under a 2017 permit (tax-abated), sold for $152K in 2019.

The abatement clock
This house pays about $514/yr under a 10-year tax abatement. In 2029 the bill reaches its full ~$2,476/yr — a step up of $1,962/yr, 2 assessment years out. Drag the slider.
now: ($176,900 assessed − $140,180 abated) × 1.3998% ≈ $514/yr
2029: $176,900 assessed × 1.3998% ≈ $2,476/yr
Flat 100% exemption (pre-2022 program, started 2019), 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.
