How the tax is worked out
Think of the final bill as three ingredients: the assessed value of the property, the exemptions subtracted from it, and the combined rate of every district the property sits in. Grant County's medians imply a derived rate of 0.82%; applied illustratively, a $400,000 home would owe about $3,292 a year, or around $274 a month spread evenly. Individual properties depart from the illustration in both directions.
