Property tax · $695/mo 1.03% of value a year — the ACS 2020-2024 median bill over the median home value for Middlesex County, MA

Insurance & upkeep · $867/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. Watertown is a city in Middlesex County, Massachusetts, close to Boston and its neighboring towns. Winters are cold here, and summers are warm, with a good deal of rain and melted snow across the year. Many residents are at a stage of life where they have settled in, and the city's median age sits a little above the middle of working life.

Work. Many residents work in schools, hospitals and social care, or in professional and business services, with manufacturing and shops also providing work. Unemployment is lower than it was a year earlier. Incomes in the town run a little below the county's, and a large share of adults hold a four-year degree.

Things to do. The Museum of Fine Arts Boston, one of the best known art museums in the country, is a short drive away. Fenway Park, a baseball stadium, is also a short drive off. For a quieter outing, the Charles River lies a longer drive away and offers open water and paths along its banks.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Middlesex County, against the rest of the country; all of them together, relatively high. 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 Middlesex County and the Boston-Cambridge-Newton, MA-NH metro.
