ZIP Code 51055

With a median household income of $72,143 and per-capita income of $47,894, ZIP code 51055 sits in middle-income territory, anchored by the town of Castana. Homes here carry a median value of $218,300, and the county-level effective property tax rate of 1.45% means owners pay a meaningful share of that value each year. Add a combined sales tax of 7.00%, and the overall tax picture takes a steady bite out of household earnings. This isn't an affluent enclave, but it's a stretch above working-class, with incomes and home prices that place it squarely in the middle of the economic spectrum.
