About this data. HMDA data is published once a year by the CFPB. The current release covers applications acted on in calendar year 2025. Figures describe applications the lender acted on, including loans it later sold. Interest rates and costs are medians on originated loans only; some depository institutions are exempt from reporting pricing fields, which is why a few cells read "—".
