At-a-glance visualization
County listing-price benchmarks, ranked.
The chart compares price levels—not affordability. Taxes, insurance, HOA dues, commuting costs and the available housing mix can change the complete picture.

This table applies the same 20% down assumption to every county only to show scale. It does not include closing costs, taxes, insurance, HOA dues or mortgage insurance.

What the county number cannot tell you
Price does not equal affordability.
A lower-priced home can carry a higher complete payment than a higher-priced home when taxes, insurance, HOA dues, mortgage insurance or financing terms differ.
Verify property taxes
Review the specific parcel, current exemptions, possible reassessment, special service areas and new-construction estimates when applicable.
Compare complete payments
Look beyond principal and interest. Add taxes, insurance, mortgage insurance and association dues when they apply.
Protect cash after closing
Down payment and closing funds are only part of the plan. Moving, repairs, maintenance and reserves still matter after you receive the keys.
Frequently asked questions
Chicagoland county home-price questions.
Which Chicagoland county had the highest typical listing price in this comparison?
DuPage County had the highest June 2026 median listing price in this six-county comparison at $497,000, followed by Lake County at $487,500.
Which county had the lowest median listing price?
Cook County had the lowest countywide median listing price in this comparison at $352,450. Cook County also contains an unusually broad mix of neighborhoods, suburbs, property types and price ranges, so a countywide figure may not resemble a specific local search.
Is the listing price the amount homes actually sold for?
No. A median listing price summarizes asking prices for active listings during the reporting month. A property's eventual contract and sale price may be higher or lower.
Why does this page use June 2026 data?
June 2026 was the newest common observation available across all six selected FRED county series when the page was researched on September 15, 2026. Using one month keeps the comparison consistent.
Does a cheaper county always mean a cheaper monthly payment?
No. Property taxes, homeowners insurance, HOA dues, mortgage insurance, loan terms and the specific property can change the complete monthly payment.
Can this calculator tell me whether I qualify?
No. It is an educational estimator. Mortgage eligibility requires an application and review of income, assets, credit, debts, occupancy, property and applicable program requirements.
