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 $6,410/yr reflects a 10-year abatement. It jumps to about $15,357/yr by 2026 — $8,947/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.
Zoned RSA5: one household by right
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
When the abatement ends, file for Homestead
An abated home cannot also take the Homestead Exemption. From 2026 it can — knocking about $1,400/yr off the full bill.

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 $6,410/yr under a 10-year tax abatement. By 2026 the bill reaches its full ~$15,357/yr — a step up of $8,947/yr. Drag the slider.
now: ($1,097,100 assessed − $639,177 abated) × 1.3998% ≈ $6,410/yr
2026: $1,097,100 assessed × 1.3998% ≈ $15,357/yr
Flat 100% exemption (pre-2022 program, started 2016), 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.
