This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

A separate historical parcel ledger ending in 2016 records $3K and a lien entry. It is shown as historical context only.

What the record is signaling

Early patterns mined across this property's dated public records. Each flag shows what triggered it and where the inference stops.

watch signalAssessment/permit mismatch

The assessment jumped 152% in 2020, but no matching permit appears in the property timeline.

Evidence: assessment moved from $300,000 to $755,000 · no permit shown in 2019-2021

Limit: Not proof of unpermitted work; reassessment, corrected data, or a permit under another parcel can also explain it.

Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, not a prediction or allegation.

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 $5,886/yr reflects a 10-year abatement. It jumps to about $12,469/yr in 2030 — $6,583/yr more. Price the full bill, not the current one.

Built 1915: 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

$2,890 in the historical tax ledger through 2016

Historical context only, not a current payoff figure; that ledger also contains a lien entry. Verify today's balance and lien status directly with Philadelphia Revenue before relying on it.

If you’re the landlord

Lead certificate is not optional

Built 1915: 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 record to dig into any number.

The abatement clock

This house pays about $5,886/yr under a 10-year tax abatement. In 2030 the bill reaches its full ~$12,469/yr — a step up of $6,583/yr, 3 assessment years out. Drag the slider.

Where this comes from

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.
