Illinois Home Loans & Mortgage Rates

Illinois offers something most states cannot: strong job markets and big-city amenities with surprisingly affordable home prices. The statewide median is approximately $286,000, and even in the Chicago metro you can find solid homes well within FHA limits.

The Chicago metro dominates the market with Cook County medians around $340,000, DuPage County around $409,000, and Lake County around $360,000. But the collar counties of Will, Kane, and McHenry offer more affordable options in the $280,000-$330,000 range. Downstate, Springfield, Peoria, Champaign, and Rockford all have medians between $150,000-$220,000, making Illinois one of the most affordable states in the Midwest.

Here is what makes Illinois unique for loan limits: every county in the state has the same FHA limit of $541,287, and the same conforming limit of $832,750. No county qualifies as high-cost. This simplifies planning considerably because you do not need to worry about which county you are buying in.

IHDA (Illinois Housing Development Authority) offers multiple DPA programs including up to $10,000 in deferred assistance, up to $6,000 in forgivable grants, and the SmartBuy program that combines $5,000 DPA with up to $40,000 in student loan relief. These programs work with FHA, VA, USDA, and conventional loans statewide.

The big caveat in Illinois is property taxes. The state has the highest effective property tax rate in the nation, with the Chicago collar counties (Lake, Kane, Will, DuPage) regularly exceeding 2%. This significantly impacts monthly housing costs and should be factored into every purchase decision.

2026 Loan Limit Takeaways

Illinois keeps it simple: $541,287 FHA and $832,750 conforming in every county. No high-cost exceptions. This covers the vast majority of homes statewide, including most of the Chicago suburbs. Buyers looking at properties above $541,287 (common in DuPage and parts of Cook County) should consider conventional financing up to $832,750. Above that, jumbo loans are needed.

Down Payment Assistance Notes

IHDA programs can be layered. The IHDAccess Forgivable ($6,000) is the most popular because it becomes free money after 10 years. SmartBuy is exceptional for buyers with student debt, offering up to $45,000 in combined assistance. The FHLBC Downpayment Plus grant can be paired with IHDA for a combined package exceeding $15,000. Chicago also has its own programs including the Chicago MCC (25% of annual mortgage interest up to $2,000/year). Income limits vary by county, with the Chicago metro (Cook, DuPage, Kane, Lake, McHenry, Will) at $143,880.

Closing Costs in Illinois

Illinois has a layered transfer tax system and uses title companies for closings.

State Transfer Tax: Illinois charges $0.50 per $500 of sale price (0.10%). On a $286,000 home, that is approximately $286. Paid by the seller in most transactions.

County Transfer Tax: All Illinois counties charge $0.25 per $500 of sale price (0.05%). On a $286,000 home, that is approximately $143. Paid by the seller.

Municipal Transfer Tax (Varies): Many municipalities charge additional transfer taxes. Chicago charges $10.50 per $1,000 ($5.25 buyer + $5.25 seller). On a $340,000 Chicago home, that adds approximately $3,570 total ($1,785 each). Evanston, Oak Park, and other suburbs have varying rates. Always check the specific municipality.

Title Company State: Illinois uses title companies for closings (not attorneys, though attorneys may be involved). Title/escrow fees typically run $1,500-$2,500. Buyer pays lender’s title insurance. Seller pays owner’s title (negotiable).

Estimated Total Buyer Closing Costs: On a $286,000 purchase with a $276,000 mortgage, expect approximately $5,700-$10,000 in total buyer closing costs (2-3.5%). In Chicago, add the buyer’s portion of the city transfer tax ($1,785 on $340,000). Outside Chicago, costs are lower due to fewer municipal taxes.

Property Taxes in Illinois

Illinois has the highest effective property tax rate in the nation. This is the single most important cost factor for homebuyers in the state.

Statewide Average: The statewide median effective rate is approximately 1.80-2.10%. The median annual property tax bill is roughly $5,400, sixth highest in the nation in dollar terms.

Chicago Collar Counties (Highest): Lake County leads at approximately 2.43-2.74%, with median bills around $8,743. Kane County is approximately 2.47%. Will County is approximately 2.12-2.41%. DuPage County is approximately 1.91%. McHenry County is approximately 2.18%. These rates mean a $350,000 home in Lake County carries roughly $8,500-$9,600 in annual property taxes.

Cook County (Chicago): The effective rate varies by location within the county but averages approximately 1.77%. The median bill is about $6,349. Cook County uses a 10% assessment ratio for residential property (compared to 33.33% elsewhere in the state), which partially offsets the high tax rates.

Downstate: Rates are generally lower. Sangamon County (Springfield) is about 1.70%. Champaign County is about 1.85%. Peoria County is about 1.75%. Southern Illinois counties can be under 1.5%.

Exemptions: Illinois offers a General Homestead Exemption ($10,000 reduction in EAV in Cook County, $6,000 elsewhere). Senior Citizens Homestead Exemption (additional $8,000 in Cook, $5,000 elsewhere). Senior Freeze exemption locks assessed value. Disabled Veterans exemption. These exemptions can meaningfully reduce bills.

On a $286,000 home in suburban Cook County, expect roughly $4,600-$5,700 per year. In the collar counties, expect $5,700-$7,200. In downstate Illinois, expect $2,800-$4,000. Property taxes are often the largest component of a monthly mortgage payment in Illinois.

USDA Loan Eligibility in Illinois

Illinois has substantial USDA eligibility in rural and semi-rural areas across the state.

Eligible areas include most of downstate Illinois outside Springfield, Champaign, Peoria, and Rockford city limits. The I-74 corridor between Champaign and the Quad Cities, much of Western Illinois (Quincy, Macomb, Galesburg), Southern Illinois (Carbondale outskirts, Marion, Herrin), and the Kankakee area all have qualifying communities.

Within the Chicago metro commuting distance, outer communities in Grundy County, DeKalb County, and southern Will County have USDA-eligible areas. The I-55 corridor south of Joliet opens up eligibility. McHenry County’s western portions and Kendall County’s outer areas may have pockets. The Rockford area (Winnebago County outskirts) has qualifying sections.
