These are mortgage loans that are "three monthly payments or more past due or in foreclosure".
Note: Fannie Mae is expected to report their Single-Family Serious Delinquency rate for September on Friday.
Although this indicates progress, the "normal" serious delinquency rate is under 1%.
The serious delinquency rate has fallen 0.62 percentage points over the last year - and the rate of improvement has slowed recently. However, at that rate of improvement, the serious delinquency rate will not be below 1% until some time in 2016.
Note: Very few seriously delinquent loans cure with the owner making up back payments - most of the reduction in the serious delinquency rate is from foreclosures, short sales, and modifications.
So even though distressed sales are declining, I expect an above normal level of Fannie and Freddie distressed sales for perhaps 2 more years (mostly in judicial foreclosure states).
