2026 taxable assessment $410,000 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $447,700; 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.”

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.

View supporting records →Legal due diligence
What this record proves—and what it does not.
These checks are triggered by this property’s actual City rows. They identify the controlling document to verify; they do not declare a use legal, a building safe, or title clear.
1 verify
VerifyA rental license does not transfer with the deedThe parcel summary indicates an active Rental License; a detailed license row is not present in this payload.
Why it mattersIf dwelling space is rented, the buyer must obtain a new annual Rental License; the seller’s license is not transferable. New applications require proof of ownership and legal occupancy, tax compliance, no open L&I violations, and lead compliance where applicable.
Verify nextPlan the buyer’s replacement license before settlement.
Open the controlling City guidance ↗Closing file: checks no public-record summary can replace5 documents/searches to assign before settlement
Property Sales Certification
The seller must obtain Philadelphia’s certificate showing the base zoning, last use in the zoning record, and open violations. The City warns that it does not prove Building Code occupancy or show zoning overlays.
Next: Obtain the fresh certificate and compare it with the CO, permits, and Atlas overlays.
Official guidance ↗Date-effective City Property Payoff
The Tax Center Property Payoff covers Real Estate Tax, Commercial Trash, and L&I abatement-work invoices. Philadelphia says it does not include business-tax debts or liens, water and sewer charges, or fines for code violations.
Next: Request the City statement effective through settlement; read every period and invoice.
Official guidance ↗Professional title and water-lien searches
OPA ownership, deed summaries, and a zero tax balance are not clear title. Mortgages, judgments, municipal claims, water liens, easements, heirs, and other encumbrances require separate searches.
Next: Use a Pennsylvania lawyer/title company and obtain owner’s title insurance; order the separate water search/payoff.
Official guidance ↗Separate water-lien guidance ↗Seller-specific tax relief is not the buyer’s bill
LOOP and low-income or senior Real Estate Tax freezes depend on the qualifying owner and continued program eligibility; a buyer cannot assume the seller’s capped or frozen bill continues. A separately verified property abatement often remains with the property for its remaining term, but program-specific new-owner filing, use, and tax-compliance conditions still must be confirmed—not inferred from the reduced assessment alone.
Next: Have Revenue or OPA identify every current benefit, model the buyer’s bill without seller-specific relief, and confirm any verified abatement in writing.
Official guidance ↗Separate water-lien guidance ↗Seller disclosure and independent inspections
For a covered Pennsylvania residential transfer, obtain the statutory seller disclosure. It reports the seller’s knowledge; it is not a warranty, title search, code review, or substitute for inspections.
Next: Have the agreement and disclosure reviewed for this transaction’s coverage and exceptions.
Official guidance ↗Informational only—not a legal opinion, title report, code inspection, tax payoff, or substitute for a Pennsylvania lawyer, title company, inspector, or tax professional.
Records to verify together
Rule-based groupings across this property's dated public records. Each flag shows the records that belong in the same verification step and where the inference stops.
Recent transition activity
The property has an unusually active paper trail worth monitoring for the next permit, inspection, deed, or listing.
Evidence: 5 permit events since 2023
Limit: Record activity alone does not establish that a sale or redevelopment is planned.
Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, not a prediction or allegation.
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
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
$6,739 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 (1544 N Darien 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.
If you’re the landlord
Licensed rental — keep it that way
Renewal requires city tax clearance and zero open L&I violations on the property. A lapsed license suspends the right to collect rent or evict.

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.

Run the numbers
What owning 1546 N Darien 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 (2022) a 30-year mortgage ran about 5.34% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 9, 2026, 5:36 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.
