Fannie Mae recently reported the Single-Family Serious Delinquency rate fell to 2.58% in March from 2.76% in February. The all-time peak was 5.59% in 2/10, and its pandemic peak was 3.32% in 8/20. For loans made prior to 2005 (2% of the portfolio), 5.66% are seriously delinquent, for loans made in 2005-2008 (also 2%), 9.65% are, and for loans made since 2009 (the remaining 96%), 2.13% are. 2005-2008 loans stink!
