jingle mail
n.— «I have heard about isolated cases of “jingle mail,” where homeowners have mailed in the keys because they can’t make the payments and no longer have any equity in their homes. That phrase was a prominent feature of the S&L bust and ensuing real-estate debacle in 1990-1991—and something we’ll be hearing lots more about in the future.» —“Even if the Fed pauses, the trend is down” by Bill Fleckenstein MSN Money Aug. 7, 2006.
