Ada and Canyon County property tax assessments will be mailed out this month, and homeowners should expect to see a substantial increase compared with last year.

Home sale prices skyrocketed in the Treasure Valley last year, leading to one of the largest increases in property tax assessments ever seen in Ada and Canyon counties.

Ada County Assessor Bob McQuade told the Idaho Statesman that he was nearly speechless looking at the numbers.

Ada County residents can expect to see about a 28% increase in their property tax assessments this year. Canyon County residents will see around 30%.
