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:

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.

Estimated annual Real Estate Tax$4,617/year

2026 taxable assessment $329,800 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $473,800; it is not the 2026 billed-year value.

Official current account balanceCheck live

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 322008000

Exemption classificationNo exemption shown

2026 taxable assessment equals the full assessed value.

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 $1,237.25 and a lien entry. It is shown as historical context only.

2014$1,237.25 total · $476.02 principal · $327.13 interest · $158.68 penalty

Assessment and sale price disagree hard

Record summary

Assessed at $474K, but it traded for $150,000 in 2024 — a 3.2× gap. Could be a non-market deed the record doesn't label, or an assessment that hasn't caught up.

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 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.

The multi-unit use has a zoning appeal on record

Appeal #ZP-2020-003717 was granted in 2020 for application is for a multi-family household living (three (3) dwelling units) in an exiswting structure the permit for the above location cannot be issued because the proposal does not comply with the following provisions of the philadelph; the City row still reports status Completed. Verify the registered use and certificate of occupancy with L&I instead of assuming the use predates the code.

If you own it

5 open violations: the clock matters

Most L&I appeals must be filed within 30 days; unsafe or imminently dangerous orders can carry a shorter deadline. Unresolved notices can lead to fees, court enforcement, City abatement work, and liens. Read the dated notice and verify its current status with L&I.

$1,237 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

If it is rented, verify the Rental License

The fetched license records do not show an active Rental License. Ownership type or a tax mailing address does not prove that tenants occupy the property; if it is rented, verify the current license and legal occupancy in eCLIPSE.

Derived from the fetched property records and linked City guidance as of 2026. Assessment treatment is not a substitute for an exemption approval, live balance, title report, license, occupancy certificate, or inspection. Informational only — not legal, tax, or investment advice.

What this record suggests

The City file documents 4 permits touching roof work. 3 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.

Flags: 5 open L&I violations · historical tax ledger through 2016 recorded $1K with a lien entry · 1 zoning/board appeal on record. Informational only — not investment advice or a consumer report (FCRA).

Where the record looks off

Places where the city's own paperwork disagrees with itself. These are flags on the data — not problems with the property.

Assessment and sale price disagree hard

Assessed at $474K, but it traded for $150,000 in 2024 — a 3.2× gap. Could be a non-market deed the record doesn't label, or an assessment that hasn't caught up.

Run the numbers

What owning 2148 N 20th 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.

Where this comes from

Methodology & freshness

This report was assembled Jul 10, 2026, 10:41 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.
