BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:
Historical tax record
Verify the current balance before relying on it.
The June 2022 delinquency snapshot was not verifiably available in this cached report. No conclusion about a match—or today’s balance—can be drawn from that absence.
A separate historical parcel ledger ending in 2016 records $12K and a lien entry. It is shown as historical context only.

From the public recordRecords to verify together
Rule-based groupings across this property's dated public records. Each flag shows the records that belong in the same verification step and where the inference stops.
Records to verify together
More than one separately dated public record deserves a current-status check.
Evidence: 1 open L&I violation · a lien number appears in the historical tax ledger through 2016 · failed L&I inspection activity in 2021, 2025, 2026
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
Recent transition activity
The property has an unusually active paper trail worth monitoring for the next permit, inspection, deed, or listing.
Evidence: 8 permit events since 2023
Limit: Record activity alone does not establish that a sale or redevelopment is planned.
Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, 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 own it
1 open violation: the clock matters
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.
$11,600 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
No active rental license on file
If this property is rented, Philadelphia requires a Rental License (via eCLIPSE) — without it a landlord cannot legally collect rent or evict, and tenants can withhold. Licensing needs tax clearance and no open violations.
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 building 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.

Run the numbers
What owning 620 Diamond St 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 (2024) a 30-year mortgage ran about 6.72% — Freddie Mac's average that year.

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.
