A mill is $1 of tax for every $1,000 of assessed value. A home's assessed value is a fraction of its market value set by state law, so the tax on a home depends on its value and the assessment rate for its class.
Colorado requires every contract to buy and sell residential real property to include a statement that the property may be in special taxing districts that can carry general obligation debt (C.R.S. §38-35.7-101). We don't decide whether a disclosure is required for a given sale.
