2026 taxable assessment $105,600 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $206,100; it is not the 2026 billed-year value.

Question or correct this record
BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:
Property tax
The estimate, live balance, and back-tax record are different.
BlockReport can calculate the annual tax from the City’s taxable assessment. Payments, credits, interest, and a current amount due live separately in Philadelphia Tax Center.
A Tax Center balance is net of bills, payments, credits, interest, and adjustments. A credit—or an amount due—is not automatically “back taxes.”
OPA 3923545002026 OPA removes $100,000 from the taxable assessment through the owner-occupant exemption.
Historical delinquency sources Record found
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 $1,253.26 and a lien entry. It is shown as historical context only.
2016$1,253.26 total · $1,068.89 principal · $16.04 interest · $10.69 penalty

View supporting records →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
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.
If you own it
$1,253 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.

What this record suggests
The City file documents 6 permits touching kitchen work, electrical work, plumbing. 5 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
Flags: historical tax ledger through 2016 recorded $1K with a lien entry. Informational only — not investment advice or a consumer report (FCRA).

Run the numbers
What owning 2504 S 6th 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 (2018) a 30-year mortgage ran about 4.54% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 11, 2026, 8:49 AM ET. Available City datasets are queried from OpenDataPhilly (phl.carto.com) and the cited City ArcGIS feeds; record queries paginate rather than silently taking a first page. For this property: Permits: queried · Violations: queried · Investigations: queried · Appeals: queried · Licenses: queried · Building certifications: queried. “Unavailable” means the source query failed or was not supplied, not “no record.” Reports re-pull on view after seven days and on an overnight rolling schedule; citywide benchmarks recompute weekly. Source dates still govern: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. The live balance and date-effective payoff must be verified in Tax Center. AI-written passages are grounded in the assembled record and rejected if they state a number the record does not hold.
