Some 71% of loans processed through an automated underwriting system last year went through Fannie Mae's Desktop Underwriter platform, including a substantial number of loans securitized by Freddie Mac and Ginnie Mae.
Fannie, Freddie and Ginnie issued a combined $170.7 billion in new single-family MBS in August, their highest monthly volume since November 2012. A big surge of refinance business was a major factor.
Private MIs and Freddie Mac posted relatively larger gains in first-time buyer business during the second quarter, though the government-insured market was still the biggest source of such loans.
Freddie saw a huge 54.2% increase in first-timer loans during the second quarter, although its 24.0% share of the agency total was the smallest of the three secondary-market platforms.
FHA/VA lending is the segment where brokers enjoy their biggest market share. In the jumbo space, they captured just 5.0% of second-quarter volume, along with a 17.1% share in the conventional-conforming market.
