Freddie's serious delinquency rate peaked in February 2010 at 4.20%.
These are mortgage loans that are "three monthly payments or more past due or in foreclosure".
Although the rate is generally declining, the "normal" serious delinquency rate is under 1%.
The Freddie Mac serious delinquency rate has fallen 0.33 percentage points over the last year, and at that rate of improvement, the serious delinquency rate could be below 1% in December or January.
Note: Fannie Mae will probably report tomorrow.
