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 $2,519/yr reflects a 10-year abatement. It jumps to about $6,056/yr in 2029 — $3,537/yr more. Price the full bill, not the current one.

Built 1900: 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 2029 it can — knocking about $1,400/yr off the full bill.

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 $2,519/yr under a 10-year tax abatement. In 2029 the bill reaches its full ~$6,056/yr — a step up of $3,537/yr, 2 assessment years out. Drag the slider.

now: ($432,600 assessed − $252,646 abated) × 1.3998% ≈ $2,519/yr 2029: $432,600 assessed × 1.3998% ≈ $6,056/yr Flat 100% exemption (pre-2022 program, started 2019), 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.
