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 $195/yr reflects a 10-year abatement. It steps up every year and reaches about $1,594/yr in 2033 — $1,399/yr more. Price the full bill, not the current one.
Built 1930: 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 2033 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.

Flags: tax-abated — the bill lags real value. Informational only — not investment advice or a consumer report (FCRA).
The abatement clock
This house pays about $195/yr under a 10-year tax abatement that steps down every year. In 2033 the bill reaches its full ~$1,594/yr — a step up of $1,399/yr, 6 assessment years out. Drag the slider.
now: ($113,900 assessed − $99,969 abated) × 1.3998% ≈ $195/yr
2033: $113,900 assessed × 1.3998% ≈ $1,594/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2023) — 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
Available City datasets are queried from OpenDataPhilly (phl.carto.com), then reports are cached and refreshed on a rolling schedule. Source dates vary: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. Other dossiers re-pull on view once stale, 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.
