Foreclosure starts fell 4 percent to 304,439 in the first half of this year, the lowest since RealtyTrac started tracking the data in 2006.
"U.S. foreclosure starts have not only returned to pre-housing crisis levels, they have fallen well below those pre-crisis levels and are still searching for a floor," said Daren Blomquist, RealtyTrac vice president.
Overall, 19 states, including California, Florida and Arizona saw foreclosure activity below or at the same level as 2006, before the economic crisis hit.
In June alone, 117,055 properties were at some stage in the foreclosure process, down 8 percent from the prior month, but up 9 percent from June 2014.
