2026 taxable assessment $86,797 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $385,900; it is not the 2026 billed-year value.

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.”

This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

View supporting records →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.
Assessment/permit mismatch
The assessment jumped 457% in 2022, but no matching permit appears in the property timeline.
Evidence: assessment moved from $47,600 to $265,200 · no permit shown in 2021-2023
Limit: Not proof of unpermitted work; reassessment, corrected data, or a permit under another parcel can also explain it.
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
Verify the current tax bill and exemption
The 2026 taxable assessment implies about $1,215/yr, while applying the same rate to the full assessment would imply about $5,335/yr — $4,120/yr more. OPA's assessment split does not establish the exemption program, expiration, or buyer eligibility. Verify the basis and live bill with OPA and Revenue.
Built 1925: 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
$6,894 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.
If you’re the landlord
Lead certificate is not optional
Built 1925: 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.

How Philadelphia’s property system works
These explainers are free because the record only helps if you know what it can—and cannot—prove. Use the linked City guidance for the controlling rule.
Permits and inspections 6 on this property
This property’s file includes BP_MECH, BP_ALTER, PP_PLUMBNG, EP_ELECTRL permit records. A permit documents authorized scope and a City process; it is not by itself proof that every described improvement was completed, remains in place, or meets today’s condition expectations.
L&I inspections are scheduled at defined stages; final inspection and required certifications are separate steps in closing out applicable work.
How construction and repair permits work ↗See City inspection stages by permit type ↗Assessments and taxes
The OPA assessment is the City’s value on the tax roll—not an asking price, appraisal, or live account balance. The taxable assessment can differ from the full assessment because the City roll records exemptions or other treatment; the report keeps those fields separate.
Your annual estimate uses the taxable assessment. Payments, credits, interest, and the amount due are maintained separately in Tax Center.
How the Office of Property Assessment works ↗Philadelphia property-tax guidance ↗Violations, cases, and status
L&I enforcement records can include warnings, notices, orders, inspections, and later resolution activity. A closed visit is still a historical record; it is not a missing event.
How L&I code enforcement works ↗City violation and order types ↗Flags: material assessment exemption — legal basis and term unverified · active rental license · historical tax ledger through 2016 recorded $7K with a lien entry. Informational only — not investment advice or a consumer report (FCRA).
The assessment exemption gap
OPA's 2026 taxable assessment implies about $1,215/year. Applying the same 1.3998% rate to the full assessed value would imply ~$5,335/year — $4,120/year more. That is a scenario, not a forecast: the assessment split alone does not identify the exemption program, approval date, expiration, transfer treatment, or live Tax Center balance.
2026: ($381,100 assessed − $294,302 exempt) × 1.3998% ≈ $1,215/yr
full-assessment scenario: $381,100 × 1.3998% ≈ $5,335/yr
The OPA amount does not prove a ten-year abatement or any other specific program. Obtain the approval history and verify the current Tax Center account; a buyer should not assume the seller's relief transfers or restarts.

Run the numbers
What owning 1209 S Wilton 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 (2018) a 30-year mortgage ran about 4.54% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 10, 2026, 9:50 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.
