What stands out
From the public recordWhat 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.
Assessment/permit mismatch
The assessment jumped 96% in 2024, but no matching permit appears in the property timeline.
Evidence: assessment moved from $274,900 to $540,000 · no permit shown in 2023-2025
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 $4,782/yr reflects a 10-year abatement. It steps up every year and reaches about $9,393/yr in 2034 — $4,611/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.
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.
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 own it
When the abatement ends, file for Homestead
An abated home cannot also take the Homestead Exemption. From 2034 it can — knocking about $1,400/yr off the full bill.
Construction next door (740 Judson St, 2026)
Excavation deeper than 5 feet, or within 10 feet of an adjacent structure, legally requires the developer to survey neighboring homes first and give owners 10 days' written notice. Insist on the pre-construction survey — it is your evidence if cracks appear.
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 $4,782/yr under a 10-year tax abatement that steps down every year. In 2034 the bill reaches its full ~$9,393/yr — a step up of $4,611/yr, 7 assessment years out. Drag the slider.
now: ($671,000 assessed − $329,380 abated) × 1.3998% ≈ $4,782/yr
2034: $671,000 assessed × 1.3998% ≈ $9,393/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2024) — 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.
