2026 taxable assessment $73,800 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $171,400; it is not the 2026 billed-year value.

Question or correct this record
BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:
Property tax
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.
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 2323134002026 OPA removes $100,000 from the taxable assessment through the owner-occupant exemption.
Historical delinquency sources Record found
$1,563.92 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.
$1,109.13 principal$58.23 interest$66.55 penalty$330.01 other charges
The snapshot’s 2022 context used $68,900 total assessment, $68,900 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.
For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”

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 1935: 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 RSA3: one household by right
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.
If you own it
$1,564 in the June 2022 delinquency snapshot
The City recorded this amount in June 2022. It may since have been paid, reduced, or increased; verify the current balance directly with Philadelphia Revenue.
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.

Run the numbers
What owning 4920 Mulberry 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 (2024) a 30-year mortgage ran about 6.72% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 11, 2026, 10:19 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.
