A Genuinely Below-Average Rate by Both National and State Comparison

Williams County's cited effective property tax rate (approximately 0.66%-0.85% across three sources reviewed this pass) runs BELOW both the ~0.89% national comparison figure used consistently across this project's records AND North Dakota's own statewide average (approximately 0.87-1.02%, SmartAsset cites 0.96%) -- a real, genuine advantage this record discloses directly.

A Real, Disclosed Cross-Source Spread on the Precise Rate

This record discloses a real, notable cross-source spread directly: citations ranged from approximately 0.66% to approximately 0.85% for Williams County's effective rate across three sources -- this record treats the 0.85% figure (Ownwell) as primary, but discloses the lower alternate citations rather than omitting them.

A Fourth, Disclosed Outlier Figure

One older-style source cited Williams County collecting approximately 1.49% "of a property's assessed fair market value" as property tax -- this record discloses directly that this figure likely reflects a different (assessed-value rather than current-effective-market-value) methodology than the other three citations, and treats it as a disclosed outlier rather than its primary figure.

Confirm a Specific Address Directly With Williams County

Given the real, disclosed rate spread across sources, buyers and movers should confirm a specific target property's current assessed value and levy directly with the Williams County Director of Tax Equalization's office rather than relying on a county median alone.
