This three-bedroom home, 359 S. Arrowhead Court in Round Lake, has a property tax bill of $6,713 | zillow.com
Property owners in Round Lake paid nearly 3.5 percent of the value of their home in taxes last year. That’s nearly three times the national average and nearly 1.5 times the state average, according to an LGIS analysis of real estate sales data in Lake County from Jan 1. to June 30.
Local Government Information Service (LGIS) publishes the Lake County Gazette.
Round Lake, population 18,375, recorded a median sale price of $197,000, based on data from the 122 properties sold during the first half of 2018. In 2017, homeowners paid a median property tax bill of $6,713, according county tax data from Lake County Assessment Office.
That’s 3.41 percent of the community’s median home value. In the U.S., the average effective property tax rate is 1.19 percent.
Put another way: a $197,000 home in Indiana, where the effective rate is 0.89 percent, would have a property tax bill of about $1,750, or nearly $5,000 less per year.
The analysis, including 65 Lake County communities, shows homeowners in Grayslake, Zion, Volo and Hainesville pay the highest property taxes in the county: 4 percent or more of their homes' value each year.
Round Lake pays the 10th highest median effective property tax rate out of those 65 communities. Its property owners, as well as those in Lakemoor, Lake Villa, Lindenhurst, Beach Park, Third Lake, Round Lake Heights, Winthrop Harbor, Long Grove and Lincolnshire, all have median effective property tax rates higher than 3 percent.
Illinois homeowners pay the second-highest property taxes in the country with an effective median rate of 2.32 percent, just behind those in New Jersey's (2.28 percent).
