Reading this house's deeds, permits and assessments…

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 $2,213/yr reflects a 10-year abatement. It steps up every year and reaches about $4,596/yr in 2033 — $2,383/yr more. Price the full bill, not the current one.

Built 1920: 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.

The last transfer was not a sale

The most recent recorded deed moved for nominal consideration, within one family. 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’re the landlord

Lead certificate is not optional

Built 1920: 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.

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 analyst below to dig into any number.

The abatement clock

This house pays about $2,213/yr under a 10-year tax abatement that steps down every year. In 2033 the bill reaches its full ~$4,596/yr — a step up of $2,383/yr, 6 assessment years out. Drag the slider.

now: ($328,300 assessed − $170,206 abated) × 1.3998% ≈ $2,213/yr 2033: $328,300 assessed × 1.3998% ≈ $4,596/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.
