How to read these numbers
- These are estimates from a survey, not a count. The American Community Survey asks a sample of households. The ± figure is the Census Bureau’s margin of error: the true value is very likely within that range of the estimate. Small places have large margins.
- “Too imprecise to report” means the margin of error is at least half of the estimate, so printing the number would suggest accuracy that does not exist. A “rough guide only” note means the margin is a quarter to a half of the estimate.
- Property tax bill and home value are medians for owner-occupied homes. Half of the homes are above the figure and half below. A median bill is not the rate set by a city or town; the bill combines taxes levied by every local government that serves the home, such as the school district and county.
- “Calculated” rows are worked out by Untax the Roof from the Census figures above them. They compare two medians, so they describe the place, not a particular household.
- Missing is not zero. Where the Census Bureau publishes no figure, this page says so.

If property taxes go unpaid in Hawaii
How it works. County-administered real-property tax foreclosure/sale; county ordinances control details
Excess sale money. Hawaii County Code 19-45 directs remaining proceeds after enforcement costs and taxes first to lienholders of record who timely claim; county audit materials describe former-owner surplus claims and later general-fund treatment. Preserve county-specific rules
These rules are set by Hawaii, not by Keaau, so this section is the same for every place in the state. Last verified 2026-09-25. See the full Hawaii entry with statute links.
