Insurance & upkeep · $440/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.

The reassessment wedge (index, Dec 2017 = 100)

Home values move monthly; tax bills move when the assessor catches up. The space between the lines is the catch-up still to come — tax data is ACS, roughly two years behind, and that lag is the point. Where a roll segment appears, named by its release year, it bridges to the median bill on current assessment rolls (AssessorSearch Data Lab, a different instrument, shown only where it agrees with ACS levels).
