“Fannie Mae and Freddie Mac mortgage delinquencies among the most creditworthy homeowners rose 50 percent in a month as borrowers said drops in income or too much debt caused them to fall behind, according to data from federal regulators . . .

Of all borrowers who ended up in default, 34 percent told Fannie and Freddie they were earning less money, about 20 percent cited excessive debt as a reason for missing mortgage payments, and 8.1 percent blamed unemployment, FHFA said.”
