Property tax · $149/mo 1.20% of value a year — the ACS 2020-2024 median bill over the median home value for Saint Louis County, MO
Insurance & upkeep · $159/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.

What it’s like
The place. Spanish Lake is a community in northern St. Louis County, home to a younger population than is typical across the country. Incomes here run well below the county's, and fewer homes are lived in by their owners than in most places, so renting is common. Fewer adults hold a four-year degree than across the county, and winters are cold while summers turn quite hot, with rain and melted snow spread through the year.
Work. Many residents work in schools, hospitals and social care, followed by professional and business services and by restaurants, hotels and entertainment. Transport, warehouses and utilities also employ a good share of people who live here. Within Spanish Lake, the National Archives and Records Administration, Collins & Hermann and Schnuck Markets are among the largest workplaces, and the county has lost a few jobs over the past year.
Things to do. The closest of the places worth knowing is Piasa, an archaeological site a short drive away. A longer drive brings you to the Gateway Arch National Park, and the Missouri Botanical Garden is another longer drive away. The Saint Louis Art Museum, also a longer drive, rounds out the better-known options.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Spanish Lake’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on St. Louis County and the St. Louis, MO-IL metro.
