"Filings" refers to "notices of election and demand" which are the first step in the foreclosure process. Filings had peaked at 4,030 in December 2007, but September 2016's total was down 89 percent from that peak.
Foreclosure "sales," which are the point in the foreclosure process where foreclosing properties are sold off at auction, are also down considerable from the 2008 peak. during September 2016, there were 158 foreclosure sales in the metro counties. That's down 38 percent from September 2015, and it's down 94 percent from the peak of 2,706 in January 2008.
Due to high price inflation for homes — and the related phenomena of high demand, moderate new construction, and rising population — foreclosure totals continue to decline, and show few signs of increasing substantially barring a significant change in current economic conditions.
