Fannie Mae and Freddie Mac both saw significant declines in the volume of defective loans that sellers had to repurchase from mortgage-backed securities pools last year, according to a new Inside The GSEs analysis. Mortgage sellers in 2017 repurchased – or made other indemnifications for defects – for just $973.5 million of single-family loans from Fannie and Freddie MBS. It was the lowest annual total since the two GSEs began filing quarterly repurchase disclosures with the Securities and Exchange Commission back in 2012. Buyback volume fell 11.6 percent from the 2016 total, including an 11.4 percent drop from the third to the fourth quarter of last year.
