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 New Jersey
How it works. Municipal tax-sale certificate system followed by Superior Court foreclosure of right of redemption; current law also provides owner-requested judicial/sheriff sale route to preserve equity
Excess sale money. P.L.2024 c.39 allows owner/heirs to request judicial or Internet auction; sale proceeds after certificate/redemption amount and allowed costs produce surplus handled under mortgage-foreclosure surplus procedures. If owner/heirs do not request that sale under current enacted law, ordinary foreclosure can proceed without auction and current statute states no equity claim against certificate holder. A 2026 bill proposing automatic surplus return is introduced but not verified enacted
These rules are set by New Jersey, not by Upper Stewartsville, so this section is the same for every place in the state. Last verified 2026-09-25. See the full New Jersey entry with statute links.
