What 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.

watch signalPost-purchase work pattern

A recorded purchase followed by 1 permit event matches the early part of a renovate-and-resell sequence.

Evidence: purchase recorded in 2025 · permit activity in 2025

Limit: This does not show that the property is listed or that a sale is planned.

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

Built 1915: 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 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’re the landlord

Lead certificate is not optional

Built 1915: 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.

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.

Run the numbers

What owning 720 S 6th St takes, at your price and your rate. Taxes are this building's actual bill from the city record; 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.
