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 $2,894/yr reflects a 10-year abatement. It jumps to about $14,468/yr in 2032 — $11,574/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, 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

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 $2,894/yr under a 10-year tax abatement. In 2032 the bill reaches its full ~$14,468/yr — a step up of $11,574/yr, 5 assessment years out. Drag the slider.

now: ($1,033,600 assessed − $826,856 abated) × 1.3998% ≈ $2,894/yr 2032: $1,033,600 assessed × 1.3998% ≈ $14,468/yr Flat 100% exemption (pre-2022 program, started 2022), 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.
