How to read these figures

HMDA records include applications, originations, purchased loans and other reportable actions. The total number of HMDA records is not the same as the number of mortgages originated. The displayed denial rate uses decisioned applications: originations, approved but not accepted, and denials.

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.
