Foreclosures showed few signs of slowing during the first half of the year, with a sharp increase in new filings occurring during the second quarter. More than one million homes had foreclosure filings -- notices of default, auction notices and bank repossessions -- during the first six months of 2012, up 2% from the previous six months, according to RealtyTrac, an online marketer of foreclosed properties. And while the number of filings was down 11% from the first six months of 2011, 20 states still saw a marked year-over-year increase. Foreclosure filings in Indiana, Pennsylvania, South Carolina, Connecticut, Florida and Illinois increased by 20% or more. Even more troubling was a surge in new foreclosure starts that occurred during the second quarter. The number of homes with new foreclosure filings was up 9% from the first quarter and was 6% higher than the second quarter of 2011, marking the first year-over-year increase since the last quarter of 2009.
