The regulator for Fannie Mae and Freddie Mac on Wednesday called on mortgage servicers to look into their foreclosure processes and work out any problems it finds while moving ahead with foreclosures with clean paperwork.

"The country’s housing finance system remains fragile and I intend to maintain our focus on addressing this issue in a manner that is fair to delinquent households, but also fair to servicers, mortgage investors, neighborhoods, and most of all, in the best interest of taxpayers and housing markets," said Edward DeMarco, acting director of the Federal Housing Finance Agency.
