Where ALLIANT CREDIT UNION stands
Statewide, ALLIANT CREDIT UNION ranks #74 of 479 lenders in Illinois by 2025 closed loans in this dataset, purchase and refinance combined. Below, its standing in the counties where it closed the most purchase loans in 2025. Loan-count ranks include every lender that reported at least 5 loans in the county; rate and cost ranks compare only lenders with at least 30 closed purchase loans there, so a one-off low median never outranks a lender with real volume.

Ranks describe 2025 closed purchase loans reported under HMDA, not current pricing. "Of N" counts the lenders eligible for that ranking: every reporting lender for loan counts, lenders with 30 or more such loans for rate and cost ranks.
County by county
Each row is this lender's median among its own closed loans in that county, with the county's all-lender median beneath it for comparison. Origination is the lender's own charges (Loan Estimate section A); points is the discount-points portion. County pages link to the full local picture.

Showing the 50 counties where this lender closed the most purchase loans in 2025, out of 86 counties with at least 5 such loans.
What these numbers are, and are not
Everything above is computed from the FFIEC's HMDA Modified Loan/Application Register, filtered to originated, first-lien, owner-occupied principal-residence loans that were not business-purpose or reverse mortgages, in county groups of at least 5 loans. These are medians of loans that already closed, not advertised offers, and the public file contains no credit scores. A lender whose customers skew toward larger loans, stronger credit, or paying discount points will show different medians than its neighbors at identical pricing. The methodology page documents every step.
The way to compare actual offers is the Loan Estimate: every lender must give you one within 3 business days of application, on the same standardized form, and its origination charges are binding. If you have one in hand, the checker compares it against your county's figures in your browser.
Common questions
What mortgage rates did ALLIANT CREDIT UNION borrowers get in 2025?
Across the counties where ALLIANT CREDIT UNION closed the most home-purchase loans in 2025, its county median rates ran from 5.812% to 6.75%. Each figure is a median of closed loans reported under HMDA, not an advertised offer, and the table on this page shows each county next to its all-lender benchmark.
Can I get these rates from ALLIANT CREDIT UNION today?
Not from this page. These are medians of loans that already closed, under those borrowers' credit profiles, loan sizes, discount points, and lock dates. To learn your own number, apply and get a Loan Estimate, which federal rules require within 3 business days and make close to free.
Why might ALLIANT CREDIT UNION's medians differ from the county median?
Partly pricing, partly customer mix. The public HMDA file contains no credit scores, so a lender serving stronger-credit borrowers, larger loans, or borrowers who paid points will show different medians than its neighbors at identical pricing.
Where does this data come from?
The FFIEC's public HMDA Modified Loan/Application Register, the loan-level data nearly every mortgage lender must file each year, filtered to originated, first-lien, owner-occupied, non-business, non-reverse loans, in county groups of at least 5.
