Historical tax record
Verify the current balance before relying on it.
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.
A separate historical parcel ledger ending in 2016 records $23K and a lien entry. It is shown as historical context only.

From the public recordWhat the record is signaling
Early patterns mined across this property's dated public records. Each flag shows what triggered it and where the inference stops.
Assessment/permit mismatch
The assessment jumped 173% in 2027, but no matching permit appears in the property timeline.
Evidence: assessment moved from $131,300 to $358,100 · no permit shown in 2026-2028
Limit: Not proof of unpermitted work; reassessment, corrected data, or a permit under another parcel can also explain it.
Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, 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
The current tax estimate is temporary
The taxable assessment implies about $2,907/yr under a 10-year abatement. The estimate steps up every year and reaches about $5,013/yr in 2034 — $2,106/yr more. Underwrite the post-abatement estimate and verify the actual bill with Revenue.
Built 1936: 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.
3 units in RSA3, a single-family district
The building's use almost certainly predates today's code — a "legal nonconforming" use. That status survives a sale but can lapse if the use is abandoned or the building sits vacant; verify the registered use with L&I before pricing it as 3 rents.
If you own it
$23,395 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 1936: 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.

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.

The abatement clock
This house’s taxable assessment implies about $2,907/yr under a 10-year tax abatement that steps down every year. In 2034 the assessment-based estimate reaches ~$5,013/yr — a step up of $2,106/yr, 7 assessment years out. Drag the slider.
now: ($358,100 assessed − $150,427 abated) × 1.3998% ≈ $2,907/yr
2034: $358,100 assessed × 1.3998% ≈ $5,013/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2024) — reassessments move both lines. After expiry an owner-occupant can claim the Homestead Exemption (~$1,400/yr off); an abated home can't hold both.

Run the numbers
What owning 3530 N 18th 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 3 licensed units × ~85% of the area's median unit rent — the whole building's income, not one unit's. Assessed value is not an asking price — set the price slider to the real one.
When this house last sold (2024) a 30-year mortgage ran about 6.72% — Freddie Mac's average that year.

Methodology & freshness
Available City datasets are queried from OpenDataPhilly (phl.carto.com), then reports are cached and refreshed on a rolling schedule. Source dates vary: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. Other dossiers re-pull on view once stale, and citywide benchmarks recompute weekly. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
