DOUGLAS COUNTY, Colo. — Property values are skyrocketing in Douglas County.

Most homes are worth between $300,000 and $450,000.  According to the Douglas County assessor, those homes on average have seen an 18 percent increase over the last two years. Homes worth $150,000 and $300,000 have shown an average increase value of 22 percent.

Homeowners are already bracing for their property taxes to increase.

“Of course, when you’re writing that check, you’re like no,” said Sarah Larson, a Parker resident. “However, it does go to things like public schools, public parks, libraries and police.”

The assessor does not set property taxes or mill rates. Property taxes are determined by multiplying a property’s assessed value by the millage or mill rate. Mill rates are set in December each year by the various taxing authorities.

State laws and other voter-approved measures impact the mill rate that is eventually adopted by each taxing authority.  Each county is required to reappraise property values every two years.

The county will be mailing out newly assessed home values starting Friday.
