2026 taxable assessment $101,200 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $109,100; 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 4331584002026 taxable assessment equals the full assessed value.
Historical delinquency sources Record found
$248.63 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2020–2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.
$23.77 principal$14.41 interest$13.46 penalty$196.99 other charges
The snapshot’s 2022 context used $34,800 total assessment, $34,800 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.”

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.
2 resolve before relying
3 verify
1 favorable dated record
Resolve before relyingA permit row needs file-level verification1 permit not marked completed: 859663 (EXPIRED). At least one row also carries a completion date, so the City fields conflict.
Why it mattersIssued work is not the same as approved final work. L&I uses final inspections and required certifications to close construction permits; expired, withdrawn, and completed are different City statuses.
Verify nextOpen the permit file and confirm final inspections, holds, and any resulting occupancy certificate.
Open the controlling City guidance ↗Resolve before relyingA dated tax balance needs a current payoff$248.63 was recorded in the City’s 2022-06 delinquency snapshot for 2020–2021.
Why it mattersThat is historical evidence, not today’s amount due. A current exemption, payment, credit, or assistance agreement can coexist with an older snapshot row.
Verify nextCheck period balances and request a dated Property Payoff statement for settlement.
Open the controlling City guidance ↗VerifyFailed inspections are dated events—not the current condition5 failed, 2 passed, and 0 CLOSED investigation outcomes are in the fetched history; the latest dated visit was PASSED on Jun 6, 2023.
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 ↗VerifyA historical business license is not current operating authorityVacant Residential Property / Lot #867790: Closed since Jul 4, 2022
Why it mattersA license record proves the licensed activity existed at that time. An inactive or expired license does not establish that the business still operates—or that it may legally reopen under the same use.
Verify nextIf business income matters, verify the current tenant, use registration, and active license in eCLIPSE.
Open the controlling City guidance ↗VerifyThe latest nominal transfer is not a market sale—or a title opinionThe latest deed in the assembled record moved for nominal consideration.
Why it mattersA $1 or nominal deed can be a valid family, estate, or entity transfer. It does not establish a sale price, clear title, or by itself prove a tangled title.
Verify nextRead the recorded deed and have the title search confirm every grantor, grantee, estate/probate step, lien, and authority to sell.
Open the controlling City guidance ↗Favorable dated recordNo open violation; closed history remains relevantThe fetched record shows 0 open and 7 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.

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.
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.
Records to verify together
More than one separately dated public record deserves a current-status check.
Evidence: $249 appeared in the City's June 2022 delinquency snapshot · failed L&I inspection activity in 2021
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
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
Built 1900: 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 RSA6: one household by right
Single-family attached, small lot. 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. 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
$249 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.
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.

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.

Where the record looks off
Places where the city's own paperwork disagrees with itself. These are flags on the data — not problems with the property.
"Built 1900" is usually a placeholder
Philadelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.
Run the numbers
What owning 3935 N 10th 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.

Methodology & freshness
This report was assembled Jul 10, 2026, 3:54 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.
