OPA has published a 2027 assessment of $385,200. It is not the 2026 billed-year value.

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

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 ~$1,118/year

$79,860 taxable basis

Difference to verify+$4,471/year
If the full assessment were taxable ~$5,589/year

$399,300 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: ($399,300 assessed − $319,440 exempt) × 1.3998% ≈ $1,118/year Full-assessment scenario: $399,300 × 1.3998% ≈ $5,589/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.

Where this comes from

Methodology & freshness

This report was assembled Jul 27, 2026, 9:34 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.
