Federal Bureau of Investigation
The FBI investigates Mortgage Fraud. The last public report on mortgage fraud was issued in 2010.
The Financial Crimes Enforcement Network is the agency that aggregates criminal fraud filings. The Bank Secrecy Act mandates that Financial Institutions and other mortgage market participants file Suspicious Activity Reports with FINCEN when they suspect suspicious transactions. Suspected Mortgage Fraud must be reported to FINCEN and FINCEN sometimes publishes statistical and descriptive reports.
