A commonly cited financial health measure for U.S. households is the percent of housing equity to total household wealth. Household equity as a percentage of household net worth has declined to about 11% from 23% during the peak (Figure 1). A June 2011 report from CoreLogic estimates that Nevada has the highest negative equity percentage with 63% of all home mortgaged properties underwater, followed by Arizona (50%), Florida (46%), Michigan (36%) and California (31%). They estimate that approximately 22% of mortgages in Illinois have debt values exceeding property values.
