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. This indicator represents the cumulative impact of foreclosure in a neighborhood measured as the unique share of residential properties that have had at least one foreclosure filing since 2005.

Foreclosure Auctions

These are properties that have completed the foreclosure process. Understanding foreclosure auction activity helps determine the flow of year-over-year of REO (real estate owned) properties into a market, how third-party demand at auctions differs based on property types, and the density of REO activity across geographies. The level of completed foreclosure auctions activity in a neighborhood indicates distress in a local housing market.
