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 $1,299/yr reflects a 10-year abatement. It jumps to about $2,800/yr in 2030 — $1,501/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.

If you own it

$315 in back taxes on record

Interest and penalties keep compounding until a Revenue payment agreement is in place — an owner-occupant agreement also stops the sheriff-sale track.

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 $1,299/yr under a 10-year tax abatement. In 2030 the bill reaches its full ~$2,800/yr — a step up of $1,501/yr, 3 assessment years out. Drag the slider.

now: ($200,000 assessed − $107,201 abated) × 1.3998% ≈ $1,299/yr 2030: $200,000 assessed × 1.3998% ≈ $2,800/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.
