What stands out
From the public recordWhat 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
The tax bill is temporary
Today's $0/yr reflects a 10-year abatement. It jumps to about $1,079/yr in 2030 — $1,079/yr more. Price the full bill, not the current one.
Built 1925: lead rules apply
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.
If you own it
When the abatement ends, file for Homestead
An abated home cannot also take the Homestead Exemption. From 2030 it can — knocking about $1,400/yr off the full bill.
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 record to dig into any number.

The abatement clock
This house pays about $0/yr under a 10-year tax abatement. In 2030 the bill reaches its full ~$1,079/yr — a step up of $1,079/yr, 3 assessment years out. Drag the slider.
now: ($77,100 assessed − $77,100 abated) × 1.3998% ≈ $0/yr
2030: $77,100 assessed × 1.3998% ≈ $1,079/yr
Flat 100% exemption (pre-2022 program, started 2020), 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.

Methodology & freshness
City datasets are fetched live from OpenDataPhilly (phl.carto.com) and cached briefly. Dossiers re-pull automatically — on view once they're a few weeks old, plus a nightly rolling sweep — and citywide benchmarks recompute weekly. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
