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$1,786/year

2026 taxable assessment $127,620 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $520,200; 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.”

Exemption classificationPartial assessment exemption — basis unverified

2026 OPA taxes $127,620 of $638,100 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.

Full-assessment scenario$8,932/year

Applying the same rate to the billed-year full assessment. OPA's numeric split does not say when or whether the current treatment changes.

Historical delinquency sources Record found

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.

A separate historical parcel ledger ending in 2016 records $7,402.23 and a lien entry. It is shown as historical context only.

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 $1,786/yr, while applying the same rate to the full assessment would imply about $8,932/yr — $7,146/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.

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.

$7,402 in the historical tax ledger through 2016

Historical context only, not a current payoff figure; that ledger also contains a lien entry. Verify today's balance and lien status directly with Philadelphia Revenue before relying on it.

Construction next door (1441 N Marston St, 2024)

Excavation deeper than 5 feet, or within 10 feet of an adjacent structure, legally requires the developer to survey neighboring homes first and give owners 10 days' written notice. Insist on the pre-construction survey — it is your evidence if cracks appear.

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.

What this record suggests

The dated deed and City-record sequence is assembled below. Read timing as a research lead, not proof of renovation, condition, or motive.

The assessment exemption gap

OPA's 2026 taxable assessment implies about $1,786/year. Applying the same 1.3998% rate to the full assessed value would imply ~$8,932/year — $7,146/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.

Where this comes from
Methodology & freshness

This report was assembled Jul 9, 2026, 10:06 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.
