What stands out
From the public record"Built 1900" is usually a placeholder
Why it mattersPhiladelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.
View supporting records →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 $10,241/yr under a 10-year abatement. The estimate steps up every year and reaches about $12,192/yr in 2033 — $1,951/yr more. Underwrite the post-abatement estimate and verify the actual bill with Revenue.
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.
If you own it
When the abatement ends, file for Homestead
An abated home cannot also take the Homestead Exemption. From 2033 it can — knocking about $1,400/yr off the full bill.
Derived from this house's public records and the city's rules as of 2026 (abatement ordinance, Homestead, rental licensing, lead certification, L&I process, excavation protections). 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.

The abatement clock
This house’s taxable assessment implies about $10,241/yr under a 10-year tax abatement that steps down every year. In 2033 the assessment-based estimate reaches ~$12,192/yr — a step up of $1,951/yr, 6 assessment years out. Drag the slider.
now: ($871,000 assessed − $139,395 abated) × 1.3998% ≈ $10,241/yr
2033: $871,000 assessed × 1.3998% ≈ $12,192/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2023) — 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.

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 4301 Main 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 (2016) a 30-year mortgage ran about 3.65% — 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.
