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.
2026 taxable assessment $174,000 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $273,900; 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 1231602002026 OPA removes $100,000 from the taxable assessment through the owner-occupant exemption.
This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

View supporting records →The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.
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 attached. 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.
Built 1900: every rental unit needs a lead-safe or lead-free certificate on file with the City. Without one: fines up to $2,000/day per unit, tenants may withhold rent, courts can order rent refunded — and no eviction will stand.
Renewal requires city tax clearance and zero open L&I violations on the property. A lapsed license suspends the right to collect rent or evict.
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.
Every fetched annual City assessment for this house, compared with its block and ZIP. The figures show assessment change, the billed-year tax estimate, dated tax records, and recorded transfers. They do not estimate market appreciation or investment return.

Case 334554 · Violation 2480271 · Code PM-306.0/1 · COMPLIED
A legacy L&I label associated with vacant-property requirements. It may concern licensing, securing, or maintaining a vacant structure; the notice and cited code control, and this row alone does not prove the property is vacant now. City marked this violation complied with; check the resolution date and live case for what was accepted.
Case 334554 · Violation 2480272 · Code PM-306.2/1 · COMPLIED

What this record suggests
The City file documents 5 permits touching kitchen work, bathroom work, electrical work, plumbing. 5 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
Flags: active rental license. Informational only — not investment advice or a consumer report (FCRA).
The city assessor's field record — the physical spec sheet behind the assessed number.
OPA field-assessment attributes. Condition and grade are the assessor's codes, not an inspection.
Places where the city's own paperwork disagrees with itself. These are flags on the data — not problems with the property.
Philadelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.
What owning 4812 Greene 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 (2017) a 30-year mortgage ran about 3.99% — 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, 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 11, 2026, 12:48 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.
