What stands out
From the public recordWhat 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 $1,256/yr under a 10-year abatement. The estimate steps up every year and reaches about $6,281/yr in 2033 — $5,025/yr more. Underwrite the post-abatement estimate and verify the actual bill with Revenue.
If you’re the landlord
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 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 $1,256/yr under a 10-year tax abatement that steps down every year. In 2033 the assessment-based estimate reaches ~$6,281/yr — a step up of $5,025/yr, 6 assessment years out. Drag the slider.
now: ($448,700 assessed − $358,973 abated) × 1.3998% ≈ $1,256/yr
2033: $448,700 assessed × 1.3998% ≈ $6,281/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.

Run the numbers
What owning 529 W Dauphin 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 2 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 (2023) a 30-year mortgage ran about 6.81% — 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.
