Home equity loans represented about 11 percent of total debt outstanding at the time. Aggregate market value fell from that point until the fourth quarter of 2011, when it reached $16.1 trillion, a decline of $6.4 trillion. Homeowner equity fell by $6.2 trillion to just 40 percent of aggregate value, as home values declined at the same time the amount of outstanding mortgage debt barely changed. By the first quarter of 2015, the total market value of housing recovered to $21.1 trillion, 6 percent below the peak valuation. The relative amount of debt and equity returned to 2006 shares, with total mortgage debt outstanding equal to $9.4 trillion (44 percent) and the value of equity at $11.7 trillion (56 percent).
