ZIP Code 18431

ZIP code 18431, centered on Damascus, sits squarely in middle-income territory, with a median household income of $56,779 and per-capita income of $35,456. Homes here carry a median value of $230,200, and the county-level effective property tax rate of 1.25% means owners pay a meaningful share of that value each year in taxes. Add a 6.00% combined sales tax on purchases, and the overall tax picture reflects a working- and middle-class area where housing costs and income stay roughly in step rather than skewing toward affluence.
