Figures are computed from Allegheny County assessment and sales records published through WPRDC (extract as of 2026-10-30), the 2027 Common Level Ratio of 49.3% from the Board of Property Assessment Appeals and Review, and 2026 millage rates from the county's community profile pages. "Likely over-assessed" means the assessment exceeds the neighborhood's median sale price per square foot times the home's finished area times the CLR by at least 10 percent, with at least $300 a year at stake. This is an estimate, not an appraisal or legal advice. Any party, including the school district, may appeal and argue for a different value.
