2026 taxable assessment $200,000 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $430,900; 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 2613639002026 OPA taxes $200,000 of $415,000 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.
See the assessment math →Applying the same rate to the billed-year full assessment. OPA's numeric split does not say when or whether the current treatment changes.
See the assessment math →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.”
What stands out

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
Verify the current tax bill and exemption
The 2026 taxable assessment implies about $2,800/yr, while applying the same rate to the full assessment would imply about $5,809/yr — $3,009/yr more. OPA's assessment split does not establish the exemption program, expiration, or buyer eligibility. Verify the basis and live bill with OPA and Revenue.
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.
The last transfer used nominal consideration
The latest deed records $100 or less and shared-name parties. That is not a usable market-sale price and can reflect a family, estate, gift, correction, or entity transfer. Inspect the deed and order a title search rather than inferring the relationship or chain.
If you own it
Verify which assessment relief applies
OPA shows a material assessment exemption, but this record does not identify its legal basis or transfer treatment. Ask OPA for the approval history; if the current treatment ends, an eligible owner-occupant may need to apply separately for Homestead relief.
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.
The investment read
How this house has moved and where it's pointed: every fetched annual City assessment, charted against its block and ZIP; appreciation includes the full-period compound rate and the latest year-over-year change. The 5-year figure simply extends that historical pace. Yield estimates rent-vs-price from area rents. Ask the record to dig into any number.

What this record suggests
The City file documents 4 permits touching kitchen work, electrical work, plumbing. 4 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
Flags: material assessment exemption — legal basis and term unverified · latest deed has shared-name parties — relationship unverified. Informational only — not investment advice or a consumer report (FCRA).
The assessment exemption gap
OPA's 2026 taxable assessment implies about $2,800/year. Applying the same 1.3998% rate to the full assessed value would imply ~$5,809/year — $3,009/year more. That is a scenario, not a forecast: the assessment split alone does not identify the exemption program, approval date, expiration, transfer treatment, or live Tax Center balance.
2026: ($415,000 assessed − $214,971 exempt) × 1.3998% ≈ $2,800/yr
full-assessment scenario: $415,000 × 1.3998% ≈ $5,809/yr
The OPA amount does not prove a ten-year abatement or any other specific program. Obtain the approval history and verify the current Tax Center account; a buyer should not assume the seller's relief transfers or restarts.

Methodology & freshness
This report was assembled Jul 10, 2026, 8:00 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.
