View supporting records →Early patterns mined across this property's dated public records. Each flag shows what triggered it and where the inference stops.
More than one public record deserves a current-status check.
Evidence: 1 open L&I violation · failed L&I inspection activity in 2024, 2025, 2026
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
A recorded purchase followed by 1 permit event matches the early part of a renovate-and-resell sequence.
Evidence: purchase recorded in 2021 · permit activity in 2022
Limit: This does not show that the property is listed or that a sale is planned.
Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, not a prediction or allegation.
The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.
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.
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.
L&I appeals must be filed within 30 days — just 6 days if a property is designated UNSAFE or IMMINENTLY DANGEROUS. Left unresolved, the city can do the work itself, bill the owner (routinely $50,000+ on a rowhouse), lien the property, and add court fines of $300+/day.
Built 1950: 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.
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.
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.

What owning 4417 Cottman Ave takes, at your price and your rate. Taxes start with an annual estimate from the City’s taxable assessment, not a current bill or balance; rent starts at the area median. Assessed value is not an asking price — set the price slider to the real one.
When this house last sold (2021) a 30-year mortgage ran about 2.96% — Freddie Mac's average that year.

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.
