2026 taxable assessment $204,980 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $496,900; 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 3630254002026 OPA taxes $204,980 of $509,800 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.

What stands out
From the public recordNew construction
Record summary$85K transfer recorded in 2017; new construction appears in a 2009 permit with a reduced taxable assessment shown, followed by a recorded transfer of $440K in 2019.
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 $2,869/yr, while applying the same rate to the full assessment would imply about $7,136/yr — $4,267/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 1925: 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.
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.

What this record suggests
The City file documents 9 permits touching kitchen work, bathroom work, drywall / interior finishing, electrical work. 9 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 $2,869/year. Applying the same 1.3998% rate to the full assessed value would imply ~$7,136/year — $4,267/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: ($509,800 assessed − $304,842 exempt) × 1.3998% ≈ $2,869/yr
full-assessment scenario: $509,800 × 1.3998% ≈ $7,136/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 1819 Wilder 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 (2019) a 30-year mortgage ran about 3.94% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 10, 2026, 11:56 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.
