This WaPo piece is light on details about how this happens, and racially disparate impacts have popped up several time in my property tax work. Mechanisms: (1) minorities have been more likely to use mortgage escrow, because of the kinds of mortgages. 1/ https://www.washingtonpost.com/business/2020/07/02/black-property-tax/

Escrow makes it less likely you'll appeal your assessment. (2) it's not (only) misassessment. Statutory property tax limits in most jrx result in lower tax rates for rapidly appreciating homes --> gentrifying areas have lower rates. NYC has radical disparities. 2/

Read Joan Youngman @landpolicy to learn about the mess of property tax rules across the country, and @ProfAtuahene for the effects of administrative dysfunction in Detroit on minority property owners.
