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$1,337/year

2026 taxable assessment $95,520 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $379,800; 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 183081000
Open Philadelphia Tax Center →Choose “View period balance” to see the tax year and any credit, interest, or delinquency.
Exemption classificationPartial assessment exemption — basis unverified

2026 OPA taxes $95,520 of $477,600 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.

See the assessment math →
Full-assessment scenario$6,685/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

This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

A separate historical parcel ledger ending in 2016 records $69.95. It is shown as historical context only.

2016$69.95 total · $64.39 principal · $0.96 interest · $0.64 penalty

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 $1,337/yr, while applying the same rate to the full assessment would imply about $6,685/yr — $5,348/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.

The last transfer used nominal consideration

The latest deed records $100 or less and shared-name parties. That is not a usable market-sale price and can reflect a family, estate, gift, correction, or entity transfer. Inspect the deed and order a title search rather than inferring the relationship or chain.

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.

$70 in the historical tax ledger through 2016

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

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 City file documents 7 permits touching electrical work, plumbing, roof work. 7 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 · historical tax ledger through 2016 recorded $70 · latest deed has shared-name parties — relationship unverified. Informational only — not investment advice or a consumer report (FCRA).

The assessment exemption gap

OPA's 2026 taxable assessment implies about $1,337/year. Applying the same 1.3998% rate to the full assessed value would imply ~$6,685/year — $5,348/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.

Obtain the approval history and verify the current Tax Center account; a buyer should not assume the seller's relief transfers or restarts.

Where this comes from
Methodology & freshness

This report was assembled Jul 10, 2026, 6:23 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.
