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 tax bill is temporary
Today's $2,843/yr reflects a 10-year abatement. It steps up every year and reaches about $14,219/yr in 2035 — $11,376/yr more. Price the full bill, not the current one.
The last transfer was not a sale
The most recent recorded deed moved for nominal consideration, within one family. That is where tangled-title problems live — budget a real title search. (Occupants untangling an inherited deed can get help from the city's Tangled Title Fund.)
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.
Who's behind it
North Darien Holdings LLC · corporate / LLC owner
• Holds an active rental license for this address
• The last transfer was a nominal/family deed, not an open-market sale
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 pays about $2,843/yr under a 10-year tax abatement that steps down every year. In 2035 the bill reaches its full ~$14,219/yr — a step up of $11,376/yr, 8 assessment years out. Drag the slider.
now: ($1,015,800 assessed − $812,700 abated) × 1.3998% ≈ $2,843/yr
2035: $1,015,800 assessed × 1.3998% ≈ $14,219/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2025) — 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.

Methodology & freshness
City datasets are fetched live from OpenDataPhilly (phl.carto.com) and cached briefly. Dossiers re-pull automatically — on view once they're a few weeks old, plus a nightly rolling sweep — 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.
