📊 How Illinois Compares to the Other 50 States
Rank 1 is the cheapest. Every row below uses the same 20% down, 6.5% APR and 30-year term as the rest of this page.
| Measure | Illinois | Rank | Lowest of the 51 |
|---|---|---|---|
| Median home price | $302,500 | #15 of 51 | West Virginia ($225,000) |

Within the Midwest region, Illinois has the #10 lowest median-price monthly payment of the 12 states there.
📍 Illinois's Largest County: Cook County
Everywhere else on this page Illinois is one set of numbers — one median price, one tax rate, one insurance premium. The U.S. Census Bureau's American Community Survey publishes the same kind of measures for individual counties, so here is Illinois's most populous county — Cook County — from the 2020–2024 ACS 5-year estimates release.
| Cook County — 2020–2024 ACS 5-year estimates | Estimate |
|---|---|
| Population | 5,182,090 |
| Median home value (owner-reported) | $324,500 |
| Median real estate taxes paid (annual) | $6,191 |
| Effective property tax rate (taxes ÷ value) | 1.91% |
| Median household income | $83,498 |
Two things to keep in mind before you use these numbers. First, the Census asks owners what their home is worth: this is a five-year survey estimate, not the sale price of homes that changed hands, so it is not comparable with the sale-price figures elsewhere on this page. Second, 1.91% is the median tax bill divided by the median home value, which is a different calculation from the statewide effective rate in the comparison table above (that one weighs total taxes collected against total value).

🏡 Purchase Example: Buying a $302,500 Home in Illinois
Using the state's median home price of $302,500, a 20% down payment, and a 6.5% 30-year fixed rate, here is the complete picture of what it costs to buy in Illinois:
| Cost Component | Amount |
|---|---|
| Home Price | $302,500 |
| Down Payment (20%) | $60,500 |
| Loan Amount | $242,000 |
| Estimated Closing Costs (3.5%) | $10,588 |
| Total Cash Needed at Closing | $71,088 |
Monthly Payment (20% Down)
| Item | Monthly |
|---|---|
| Principal & Interest | $1,530 |
| Property Taxes (1.88%) | $474 |
| Homeowners Insurance | $112 |
| PMI (not needed at 20% down) | $0 |
| Total Monthly Payment | $2,115 |
Annual income needed (28% DTI): $91,000/yr
PMI Scenario: What If You Put Only 10% Down?
With a 10% down payment ($30,250), you'd have a loan of $272,250 and would need to pay Private Mortgage Insurance (PMI) at roughly 0.85% of the loan annually:
| Item | 10% Down | 20% Down (savings) |
|---|---|---|
| Principal & Interest | $1,721 | $1,530 |
| Monthly PMI | $193 | $0 |
| Total PITI+PMI | $2,499 | $2,115 |
The lower down payment costs you an extra $384/month (P&I + PMI). You would need $108,000/yr to qualify under the 28% DTI rule. PMI can typically be canceled once you reach 20% equity.
First-year interest: In year one, $15,650 of your payments go to interest alone. Over the full 30-year term, you'll pay $308,658 in total interest.
