Our analysis, 2025
First Security Bank, of Byron, Minnesota, is a small, long-standing Rochester lender, ranking 36 of 276 lenders there in 2025.
A thinner year
It made 39 loans, down 20%, while similar lenders (state non-member banks making between half and twice as many loans) grew 2%. On a book this small, a handful of loans makes the difference: it made 49 in 2024. It filed no HMDA report from 2018 to 2022; those years are gaps in the record, not years without lending.
Purchase loans, a little larger than peers'
Purchases made up 64.1% of its loans and refinances 30.8%. All were conventional. Its typical loan was $225,000, against $165,000 at similar lenders, higher than at about seven in ten of them. With 39 loans, shares by borrower group rest on too few loans to read much into.
Similar lenders: same lender type, originations between half and twice the lender's in the data year. Written from the 2025 HMDA data and checked figure by figure against it.
FIG. 1 — LOANS ORIGINATED, 2023–2025
39 loans in 2025, against a peak of 49 in 2024.
Originated means the loan was made: applications denied, withdrawn or not accepted are not counted. Years with no HMDA report from this lender are left out: since 2020 a bank making fewer than 100 closed-end loans a year need not report. First Security Bank took 39 applications in 2025.
