Insurance, % of value
What this number means, its source and the limits of using it.
Guide updated · Source dates are shown in the app
Say two homes have different values. This expresses the modeled annual premium as a share of the value used, so places can be compared on a common basis.
Reading the number
Group: Cost to own. Units: fraction. Read the selected geography and compare the same measure at the same level.
Source and date
Treasury FIO / NAIC homeowners premiums. No fixed refresh interval; check the source date shown in the app.
Published coverage: ZIP x year (2018-2022). Adjusted premium estimates do not change the historical period of nonrenewal observations.
A guide update is not a data refresh. The source period and collection date, when available, are on the app’s data details. A missing date is unknown, never today. Check freshness.
Access and limits
Free and above by default. The app’s current lock is authoritative if settings change. Derived measures also need their input measures open. A missing number is not zero. What each plan shows.
