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 $3,332/yr under a 10-year abatement. It jumps to about $7,140/yr in 2028 — $3,808/yr more. Underwrite the post-abatement estimate and verify the actual bill with Revenue.

3 units in RSA5, 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

When the abatement ends, file for Homestead

An abated home cannot also take the Homestead Exemption. From 2028 it can — knocking about $1,400/yr off the full bill.

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 $3,332/yr under a 10-year tax abatement. In 2028 the assessment-based estimate reaches ~$7,140/yr — a step up of $3,808/yr, 1 assessment year out. Drag the slider.

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 1818 Harlan 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.

Where this comes from
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.
