The Federal Housing Finance Agency is tackling all things fraud related, from prevention to managing and detecting the various types of potential fraud, according to recently issued guidance to Fannie Mae and Freddie Mac. The FHFA warned that mortgage fraud may occur in loans purchased for the GSEs’ own portfolios or for securitization. Fraud can also be committed by a number of external and internal parties and can occur as part of the origination, underwriting, or closing process or in conjunction with the servicing of a loan on behalf of Fannie or Freddie.The GSEs’ boards of directors are responsible for making sure that the GSEs have appropriate policies in place for preventing and detecting fraud, according to the guidance.
