2026 taxable assessment $364,800 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $364,900; 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 0114293002026 taxable assessment equals the full assessed value.
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.
The assessment or license record describes multiple units while the zoning district is generally single-family. That does not establish whether the use is lawful, nonconforming, abandoned, or incorrectly coded. Verify the registered use and Certificate of Occupancy with L&I before pricing multiple rents.
This home reads owner-occupied but shows no Homestead Exemption, which removes $100,000 from the taxable assessment (worth up to $1,399/yr). Applying through the City is free and takes minutes.

What this record suggests
The City file documents 4 permits touching kitchen work, bathroom work, plumbing. 1 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
Flags: 1 zoning/board appeal on record. 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.
What owning 1841 S 4th 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 (2021) a 30-year mortgage ran about 2.96% — 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, 9:10 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.
