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 current tax estimate is temporary

The taxable assessment implies about $500/yr under a 10-year abatement. It jumps to about $4,999/yr in 2030 — $4,499/yr more. Underwrite the post-abatement estimate and verify the actual bill with Revenue.

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 abatement clock

This house’s taxable assessment implies about $500/yr under a 10-year tax abatement. In 2030 the assessment-based estimate reaches ~$4,999/yr — a step up of $4,499/yr, 3 assessment years out. Drag the slider.

2027~$500/yrestimated from assessment

now: ($357,100 assessed − $321,381 abated) × 1.3998% ≈ $500/yr 2030: $357,100 assessed × 1.3998% ≈ $4,999/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.

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.

About this data & fine print

Answers are generated by an AI agent querying available City of Philadelphia open data at the moment you ask: OPA property assessments, Recorder of Deeds transfer records, L&I permits, violations & licenses, dated Dept. of Revenue tax records, Zoning Board appeals, Police incident reports, Philly311 requests, and School District of Philadelphia catchment and school data.

For an explicit web search or a current listing/news question, the agent may also search the public web through OpenRouter and must link every web-derived claim. Public listing pages can be stale and are not direct or comprehensive MLS access.

Property-level tax data is historical: the delinquency snapshot is dated June 2022 and the separate detailed ledger ends in 2016. Neither shows what is owed today; verify a current balance with Philadelphia Revenue.

City data is published as-is and can lag, contain errors, or be corrected later; school performance datasets run years behind and are labeled with their school year. AI answers can contain mistakes — verify anything that matters against the official record (property.phila.gov, atlas.phila.gov) before acting on it.

Informational only. Not legal, financial, or investment advice. Not a consumer report under the FCRA — it may not be used to decide anyone's eligibility for housing, tenancy, employment, credit, or insurance.
