If you’re trying to sell a home in Boston, Revere or Chelsea, you’re more likely to be competing with foreclosed or other types of distressed properties.

 Suffolk County ranks #1 In terms of density of distressed residential properties – meaning homes that have been foreclosed or where a petition to foreclose has been filed or an auction scheduled.

 Almost 3 percent of the properties in Suffolk County are distressed, according to data from The Warren Group. Plymouth County comes in second with 2.5 percent of its properties in distress. Two to three residential properties out of every 100 in those counties are in the foreclosure process.
