Property tax · $352/mo 0.91% of value a year — the ACS 2020-2024 median bill over the median home value for Carroll County, MD
Insurance & upkeep · $499/mo insurance, maintenance and repairs together, from the BLS Consumer Expenditure Survey — the national figure for mortgaged homeowners, scaled to this market's home value. BLS publishes the three bundled and they cannot be split.
Both are priced off the same month's home value, so they rise with the market. Neither is a quote — a specific home's bill depends on its assessment, its age and its insurer.
