Property tax
$1,120/year estimated property tax
2026 taxable assessment $80,000 × 1.3998%. This is an estimate, not a bill or account balance. The City maintains payments, credits, interest, and the current amount due.
OPA has published a 2027 assessment of $400,000. It is not the 2026 billed-year value.
Payments, credits, interest, and the current amount due are maintained by the City.
OPA 2520805002026 OPA taxes $80,000 of $400,000 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.
See the assessment math →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 $3,163.45 and a lien entry. It is shown as historical context only.
For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”
The assessment exemption gap
OPA's 2026 roll shows a partial assessment exemption. The annual difference is measurable; the reason for it and what happens after a sale are not established here.
$80,000 taxable basis
$400,000 scenario basis
- Legal basis or program
- Approval or expiration date
- Treatment after a sale
- Current Tax Center balance
Show the assessment math
2026: ($400,000 assessed − $320,000 exempt) × 1.3998% ≈ $1,120/year
Full-assessment scenario: $400,000 × 1.3998% ≈ $5,599/year
Do not treat the full-assessment scenario as inevitable or assume the current relief transfers. Obtain the approval history and verify the live Tax Center account before relying on either number.

Rental · Initial issue date Feb 14, 2023 · Terminal license date Apr 14, 2025
A license is an L&I registration, not proof that a business is open, operating today, or located at this storefront. Dates are license dates. Events are deduped by parcel, business identity, and license type, so a renewal is not shown as another opening. Other permit and filing types remain in the full source ledger.

Methodology & freshness
This report was assembled Jul 25, 2026, 12:07 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.
