Americans who lost their home to foreclosure are slow to return to home ownership. About 1.9 million of the 3.1 million home owners who were foreclosed on between 2007 and 2013 have passed the 7 year mark, the typical time required to sufficiently improve a credit score. But less than half are rebuying homes. Arizona is a leader in boomerang buyers, with about 32% of its foreclosed home owners purchasing again – 10 percentage points higher than the national average.
