Cumulative Foreclosure Filings Activity

Annual levels of foreclosure filing activity likely do not convey the impact that foreclosure has had in a particular community, as geographies vary in density and size, and the drivers behind the Great Recession foreclosure crisis led to very different annual patterns of foreclosure filing activity across the region.

The level of completed foreclosure auctions activity in a neighborhood indicates distress in a local housing market.
