$9,218/year estimated property tax

2026 taxable assessment $658,512 × 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 $686,500. It is not the 2026 billed-year value.

Current City balanceCheck Tax Center

Payments, credits, interest, and the current amount due are maintained by the City.

Exemption classificationPartial assessment exemption, basis unverified

2026 OPA taxes $658,512 of $807,000 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.

Historical delinquency sources No current conclusion

This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

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.

Using OPA's taxable amount ~$9,218/year

Difference to verify+$2,078/year
If the full assessment were taxable ~$11,296/year

$807,000 scenario basis

The assessment roll does not identify
  • Legal basis or program
  • Approval or expiration date
  • Treatment after a sale
  • Current Tax Center balance
Show the assessment math 2026: ($807,000 assessed − $148,488 exempt) × 1.3998% ≈ $9,218/year Full-assessment scenario: $807,000 × 1.3998% ≈ $11,296/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.

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.

Where this comes from

Methodology & freshness

This report was assembled Jul 28, 2026, 4:47 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.
