Ada County, ID Property Records & Statistics
Ada County has a median rent of $1,279, well above the Idaho figure of $841.50 and the national figure of $840.25. Home values follow the same pattern: the median home value is $429,400, compared with $245,725 statewide and $173,750 nationally. Renter-occupied housing makes up 28.07% of homes, higher than the state's 21.77% and the national 21.81%, which points to a sizable rental market alongside a high-priced ownership market.
The county's median property tax rate is 0.6%. That is above the state rate of 0.52% but below the national rate of 0.74%. Because home values are so high, even a moderate rate can mean a substantial tax bill for owners.
Incomes help offset some of the cost of living. Median household income in Ada County is $84,598, compared with $63,832 in Idaho and $65,108 nationally. The unemployment rate is 1.96%, lower than the state's 2.22% and the national 2.87%, suggesting a strong local job market.
Overall, the figures describe a county where housing is expensive relative to both the state and the country, but where higher incomes, low unemployment, and a tax rate that stays under the national level support a busy and active housing market.

Assignment and release records track what happens to a mortgage after it is recorded. An assignment shows that a mortgage was transferred from one lender or loan holder to another, while a release shows that a mortgage was paid off and the lien removed from the property.
