The local Fox 25 did an "undercover" story on foreclosures in Massachusetts last night during their news broadcast. Although the report was much more bombastic than necessary (as local news stories are apparently required to be), there was a good bit of foreclosure data placed on their website. They have a list of Massachusetts towns ranked from highest to lowest foreclosure rates.
