2026 taxable assessment $67,200 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $226,000; 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 2520761012026 OPA taxes $67,200 of $280,000 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
From the public recordNew construction
Why it mattersBought for $43K in 2024, built new under a 2024 permit (reduced taxable assessment shown), sold for $280K in 2025.
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 $941/yr, while applying the same rate to the full assessment would imply about $3,919/yr — $2,978/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.
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.
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 8 permits touching electrical work, plumbing. 8 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. Informational only — not investment advice or a consumer report (FCRA).
The assessment exemption gap
OPA's 2026 taxable assessment implies about $941/year. Applying the same 1.3998% rate to the full assessed value would imply ~$3,919/year — $2,978/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: ($280,000 assessed − $212,776 exempt) × 1.3998% ≈ $941/yr
full-assessment scenario: $280,000 × 1.3998% ≈ $3,919/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.

Run the numbers
What owning 2135 E William 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.
When this house last sold (2025) a 30-year mortgage ran about 6.6% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 10, 2026, 12:53 PM 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.
