How Are Loan Limits Determined?
The FHFA sets conforming loan limits annually based on changes in average U.S. home prices. The Housing and Economic Recovery Act (HERA) of 2008 established the formula used to calculate these limits.
Under this framework:
-
The national baseline limit is based on changes in average U.S. home prices.
-
For high-cost areas, FHFA evaluates whether 115% of a county’s median home value exceeds the baseline.
-
If it does, the loan limit may be increased, capped at 150% of the baseline amount.
Since Illinois counties do not exceed 115% of the national median home price, all counties remain at the baseline conforming loan limit of $832,750 for 2026.

Why Do Loan Limits Matter?
Loan limits set the maximum amount you can borrow with a conforming loan, a mortgage eligible for purchase by government-sponsored entities like Fannie Mae and Freddie Mac. These limits play a key role in determining your loan options, approval requirements, and overall borrowing costs.
First, staying within the conforming limit typically means access to lower interest rates. Lenders view these loans as lower risk, which often results in more competitive pricing for borrowers.
Second, conforming loans usually come with simpler qualification requirements. Borrowers may benefit from lower minimum credit score thresholds, higher allowable debt-to-income ratios, and less restrictive documentation compared to jumbo loans.
Third, conforming loan status affects down payment flexibility and program eligibility. Many conforming programs allow down payments as low as 3% to 5%, and they may qualify for state or federal assistance programs that exclude jumbo loans.
Finally, understanding your local conforming loan limit helps you plan strategically. It influences how much you can offer on a home, how you structure your financing, and whether alternative loan options may be needed in the future.
Benefits of Staying Within Loan Limits
-
Lower Interest Rates: Conforming loans generally offer more competitive rates than jumbo loans.
-
Easier Qualification: Lower lender risk often allows more flexible credit and debt-to-income requirements.
-
Lower Down Payments: Many conforming programs permit down payments as low as 3% to 5%, compared with 20% or more for jumbo loans.
-
Access to Assistance: Staying within loan limits can help you qualify for certain state and federal programs that exclude jumbo loan amounts.
Frequently Asked Questions

The conforming loan limit across all Illinois counties for 2026 is $832,750.

Do conforming loan limits change every year?
Yes. The FHFA reviews and updates conforming loan limits annually based on nationwide home price trends.
Are conforming loan limits the same for multi-unit properties?
No. Loan limits increase with the number of units. Duplexes, triplexes, and fourplexes have higher maximum loan limits than single-family homes. Refer to the table above for a full breakdown.
