Median assessed value per recorded interior square foot, among blocks with at least 12 homes.
Source: OPA assessments · City of Philadelphia
Compounded change in the median assessment for an exact paired cohort of at least 12 current homes with records in 2016 and the latest billed year. Current year-built records after 2016 are excluded. Missing build years and historical classification changes can remain, so this is an assessment-change screen, not market appreciation or a sale-price index.

Change between the latest two consecutive published assessment rolls for a stable cohort of at least 12 homes that existed by 2016—not a sale-price change.

The median sale premium for the same homes, with each recorded sale from the past two years compared with that home’s assessment roll for the sale year. Every block has at least five matched sales; nominal transfers and package-looking price multiples are excluded. Renovation before resale can still widen the gap.

Citywide, from owner names and assessment fields on the current OPA roll. Companies, agencies and institutions only. Individually held property is never named on a list, and name aggregation does not establish beneficial ownership.

Entity and agency owner names on the current OPA assessment roll, ranked by matched parcel count. This is recorded-name aggregation, not proof of beneficial ownership or control.

Properties with one or more separately dated records: a June 2022 tax-delinquency snapshot entry, open L&I violations, or an active vacant-property license. The tax figure is historical and does not show a current balance or an owner’s intent to sell.
