OPA also publishes a 2027 assessment of $533,800; it is not the 2026 billed-year value.
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 3011632002026 OPA taxes $186,048 of $581,400 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.

The 2026 taxable assessment implies about $2,604/yr, while applying the same rate to the full assessment would imply about $8,138/yr — $5,534/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.
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.
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.
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.

What this record suggests
The City file documents 11 permits touching kitchen work, bathroom work, electrical work, plumbing. 10 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 · 2 zoning/board appeals on record. Informational only — not investment advice or a consumer report (FCRA).
OPA's 2026 taxable assessment implies about $2,604/year. Applying the same 1.3998% rate to the full assessed value would imply ~$8,138/year — $5,534/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: ($581,400 assessed − $395,373 exempt) × 1.3998% ≈ $2,604/yr
full-assessment scenario: $581,400 × 1.3998% ≈ $8,138/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.

What owning 1918 Webster 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.
Scenario for orientation, not advice. Assumes a 30-year fixed loan, $1,400/yr insurance, 1% of price/yr maintenance, and buyer cash equal to the down payment plus 4%. Taxes use this parcel's taxable assessment with an optional full-assessment stress test, not a live Tax Center balance. Cash flow and returns exclude vacancy, management, utilities, HOA or condo fees, leasing costs, income tax, and unplanned capital work.

This report was assembled Jul 10, 2026, 9:58 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.
