Massachusetts residents who lost their homes to foreclosure between 2008 and 2011 have until Friday to apply for a one-time payment connected to a $25 billion national mortgage settlement reached by attorneys general and five major lenders.

The estimated 21,000 state residents eligible to receive between $1,500 and $2,000 risk losing out on the payment if they fail to act this week, according to Massachusetts Attorney General Martha Coakley.
