The Fannie Mae serious delinquency rate peaked in February 2010 at 5.59%.
Freddie Mac reported that the Single-Family serious delinquency rate declined to 3.51% in March, down from 3.57% in February. Freddie's rate is down from 3.63% in Feburary 2010. Freddie's serious delinquency rate peaked in February 2010 at 4.20%.
These are loans that are "three monthly payments or more past due or in foreclosure".

The "normal" serious delinquency rate is under 1%, so there is a long way to go.
Note: LPS reported the serious delinquency rate (including in foreclosore) was about 7.5% in March. That includes the Fannie and Freddie loans with serious delinquency rates at less than half the industry average. This is also a reminder of how bad the non-Fannie/Freddie loans are performing.
