Why approval and denial rates diverge. Approval (origination) rate and denial rate do not sum to 100% - HMDA records several outcomes beyond approved-and-funded, including files that were approved but not accepted by the applicant, withdrawn, or closed for incompleteness. Old Second National Bank's 73.8% origination rate tells you how often an application turned into funded money; the 8.9% denial rate is a separate read on underwriting strictness. The most frequently cited denial reasons in this file were Debt-to-income ratio, Credit history, Other, which together explain the majority of rejections. Most activity concentrated in Conventional loans (1,117 applications).
How to read this page. These figures are aggregate HMDA disclosures, they describe this lender's overall 2024 book, not your individual odds. Approval and denial rates are shaped by the applicant mix a lender actually receives: credit profile, loan-to-value, debt-to-income, property type, and geography. A lower denial rate at one lender versus another does not necessarily mean easier underwriting, it often reflects borrower self-selection and loan-product specialization. This page is informational data reporting, not financial, legal, or mortgage advice. Compare multiple lenders, read your Loan Estimate carefully, and consult a licensed mortgage professional before applying. Data reflects 2024 disclosures published by the CFPB in 2025.
