CFPB consumer submissions
Complaints are consumer submissions and are not findings of wrongdoing.
CFPBComplaint coverage dates are shown with the records. They are not the profile observed date.
CFPB Mortgage Complaint Activity
No published complaint result found
No mapped CFPB mortgage complaint activity is currently published on this profile under U.S. Mortgage Index's verified entity-matching methodology. This is not a finding that no complaint exists under another company name, affiliate, source attribution, period, or configuration.
This does not establish that no record exists elsewhere. It means USMI does not currently have a published matching result for this profile.
CFPB complaint records are submissions received by the Consumer Financial Protection Bureau.
Complaint volume is context. It is affected by company size, servicing volume, time in market and consumer awareness. It is not proof of wrongdoing.
Current USMI CFPB mortgage complaint coverage begins December 1, 2012. Data through August 20, 2026.
