2026 taxable assessment $0 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $229,500; 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 8810001802026 OPA shows a zero or de minimis taxable assessment. The open assessment split does not establish the exemption's legal basis, continuing eligibility, or treatment after a transfer.
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.”

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 resolve before relying
3 verify
Resolve before relyingZoning approval is not the occupancy fileThe record identifies more than one dwelling/use.
Why it mattersPhiladelphia says a zoning approval or Property Sales Certification can identify a use without proving that it was established under the Building Code. A change of use, unit count, exits, or fire rating can require a Building Permit and Certificate of Occupancy.
Verify nextVerify the lawful use, unit count, associated construction permits, and Certificate of Occupancy with L&I.
Open the controlling City guidance ↗VerifyResidential form does not establish rental useOPA classifies the parcel as multi-family; no active Rental License row matched.
Why it mattersA multi-unit or mixed-use classification does not prove that space is currently rented. If dwelling space is rented, Philadelphia generally requires a current Rental License and related occupancy, tax, violation, and lead compliance.
Verify nextConfirm actual occupancy first; if any unit is rented, verify the license and legal unit count with L&I.
Open the controlling City guidance ↗VerifyOPA shows a full exemption; its legal basis is unverifiedOPA currently marks the land and building assessment fully tax-exempt; BlockReport does not receive the exemption determination or basis.
Why it mattersFull OPA exemptions can have different legal bases, including government, religious, charitable/institutional, veteran, or other treatment. The current owner/use record is not a buyer’s tax forecast.
Verify nextConfirm the exact exemption basis, buyer eligibility, and next tax-year treatment directly with OPA.
Open the controlling City guidance ↗VerifyA separate Commercial Trash account may applyOPA classifies the parcel as multi-family. BlockReport does not receive a current Commercial Trash account balance.
Why it mattersPhiladelphia charges qualifying small commercial, mixed-use, and multi-unit properties that use City collection; exemptions and private collection can change applicability. A use category alone does not prove a fee is due.
Verify nextCheck the Commercial Trash account inside the date-effective Property Payoff.
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. Because OPA dates this building before 1978, separately obtain the required federal/City lead disclosures and any test results.
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.
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 1960: 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.
If you’re the landlord
If it is rented, verify the Rental License
The fetched license records do not show an active Rental License. Ownership type or a tax mailing address does not prove that tenants occupy the property; if it is rented, verify the current license and legal occupancy in eCLIPSE.
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 building 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 609 S 15th 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 (1986) a 30-year mortgage ran about 10.19% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 9, 2026, 11:03 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. “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.
