Mortgage repurchases and indemnifications on loans sold to Fannie Mae and Freddie Mac surged higher in the first quarter of 2017, according to a new Inside The GSEs analysis of disclosure reports filed with the Securities and Exchange Commission. Sellers repurchased or indemnified the GSEs for losses on $238.6 million of home loans during the first three months of the year. That was up 15.1 percent from the fourth quarter of 2016. But it’s a drop in the bucket compared to the amount of single-family business Fannie and Freddie do. In 2015, for example, the two GSEs issued $824.76 billion of single-family mortgage-backed securities.
