2026 taxable assessment $127,200 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $150,400; 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 4063075002026 taxable assessment equals the full assessed value.
Historical delinquency sources No current conclusion
This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.
For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”

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.
4 verify
1 favorable dated record
VerifyA rental license does not transfer with the deed1 active Rental License record matched.
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 ↗VerifyTax mail goes outside Philadelphia; owner residence still needs verificationOPA mails the property tax record outside Philadelphia (PO BOX 297257, BROOKLYN NY, 11229).
Why it mattersA tax mailing destination does not establish where the owner lives. If a rental owner lives outside Philadelphia, the City requires a managing agent with a Philadelphia mailing address; the owner remains legally responsible.
Verify nextVerify the buyer’s residence and, if the buyer will live outside Philadelphia, identify the Philadelphia managing agent on the new license application.
Open the controlling City guidance ↗VerifyLead compliance is a separate recordOPA records a 1920 build year; BlockReport does not receive the Health Department’s unit-level lead certificate file.
Why it mattersPhiladelphia requires covered pre-March-1978 rentals to be certified lead-safe or lead-free for a new or renewed lease and for a new or renewed Rental License. A certificate is unit-specific; a renovation does not by itself create an exemption.
Verify nextRequest the current lead certificate or City exemption for every dwelling unit.
Open the controlling City guidance ↗VerifyFailed inspections are dated events—not the current condition4 failed, 1 passed, and 1 CLOSED investigation outcome are in the fetched history; the latest dated visit was CLOSED on Oct 18, 2012.
Why it mattersA PASSED or FAILED value applies to that inspection visit. CLOSED is a separate source status; none of the three alone proves the parent permit or violation case closed—or describes today’s condition.
Verify nextOpen the parent case/permit for each material failure and confirm its later disposition.
Open the controlling City guidance ↗Favorable dated recordNo open violation; closed history remains relevantThe fetched record shows 0 open and 2 historical violations across 2 cases.
Why it mattersA closed case is materially better than an open one, but it does not by itself prove that every altered use, unit, or concealed condition matches today’s approvals.
Verify nextUse the closed cases to target the inspection and occupancy-file review.
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 1920: 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
Lead certificate is not optional
Built 1920: every rental unit needs a lead-safe or lead-free certificate on file with the City. Without one: fines up to $2,000/day per unit, tenants may withhold rent, courts can order rent refunded — and no eviction will stand.
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.
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.

Run the numbers
What owning 6529 Guyer Ave 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 (2021) a 30-year mortgage ran about 2.96% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 10, 2026, 2:54 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.
