View supporting records →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
The tax bill is temporary
Today's $5,637/yr reflects a 10-year abatement. It jumps to about $13,983/yr in 2030 — $8,346/yr more. Price the full bill, not the current one.
The last transfer was not a sale
The most recent recorded deed moved for nominal consideration. 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 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.
If you’re the landlord
Licensed rental — keep it that way
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 record to dig into any number.

The paper trail

Flags: tax-abated — the bill lags real value · active rental license. Informational only — not investment advice or a consumer report (FCRA).
The abatement clock
This house pays about $5,637/yr under a 10-year tax abatement. In 2030 the bill reaches its full ~$13,983/yr — a step up of $8,346/yr, 3 assessment years out. Drag the slider.
now: ($998,900 assessed − $596,200 abated) × 1.3998% ≈ $5,637/yr
2030: $998,900 assessed × 1.3998% ≈ $13,983/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.

Run the numbers
What owning 829 S 4th St takes, at your price and your rate. Taxes are this building's actual bill from the city record; rent starts at 3 licensed units × ~85% of the area's median unit rent — the whole building's income, not one unit's. Assessed value is not an asking price — set the price slider to the real one.

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.
