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.

Estimated annual Real Estate Tax$2,272/year

2026 taxable assessment $162,300 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $156,400; it is not the 2026 billed-year value.

Official current account balanceCheck live

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 332250700
Open Philadelphia Tax Center →Choose “View period balance” to see the tax year and any credit, interest, or delinquency.
Exemption classificationNo exemption shown

2026 taxable assessment equals the full assessed value.

Historical delinquency sources No current conclusion

The June 2022 delinquency snapshot was not verifiably available in this cached report. No conclusion about a match—or today’s balance—can be drawn from that absence.

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 record

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

Built 1950: 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

$1,399/yr may be unclaimed

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.

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: the city's assessed value (not a listing price) over 12 years, charted against its block; appreciation is that history's pace, and the 5-year figure simply extends it. Yield estimates rent-vs-price from area rents. Ask the record to dig into any number.

Methodology & freshness

This report was assembled Jul 9, 2026, 8:38 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. “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.
