Negative equity, often referred to as being "underwater" or "upside down," applies to borrowers who owe more on their mortgages than their homes are worth. Negative equity can occur because of a decline in home value, an increase in mortgage debt or both.

Negative equity peaked at 26 percent of mortgaged residential properties in Q4 2009 based on CoreLogic equity data analysis, which began in Q3 2009.
The national aggregate value of negative equity was approximately $283 billion at the end of Q1 2017, down quarter over quarter by approximately $2.6 billion, or 0.9 percent, from $285.5 billion in Q4 2016 and down year over year by approximately $21.5 billion, or 7.1 percent, from $304.5 billion in Q1 2016.

"Homeowner equity increased by over $750 billion during the last year, the largest increase since mid-2014," said Frank Martell, president and CEO of CoreLogic. "The rising cushion of home equity is one of the main drivers of improved mortgage performance. It also supports consumer balance sheets, spending and the broader economy."
