Lender Processing Services (LPS) says data it’s collected through the end of June show an abrupt increase in the industry’s mortgage delinquency rate and a smaller uptick in the national foreclosure inventory.

The company reports the home loan delinquency rate – defined as loans 30 or more days past due, but not yet in foreclosure – rose to 8.15 percent last month.

That’s up 2.4 percent from a rate of 7.96 percent at May month-end. Compared to this time last year, however, delinquencies are down 14.7 percent.

The U.S. foreclosure inventory was up on both a monthly and annual basis. LPS assesses foreclosure inventory as the share of mortgages that have been referred to a foreclosure attorney but haven’t reached the final stage of foreclosure sale.

The foreclosure rate stood at 4.12 percent at the end of June, up 0.2 percent from May and 12.8 percent from June 2010.

Altogether, LPS says there are some 6,452,000 mortgages going unpaid in the United States.

Of these, 2,167,000 are in the process of foreclosure. The remaining 4,285,000 are past due by one or more payments but have not been referred to a foreclosure attorney, with 1,906,000 of the loans in this bucket overdue by 90 days or more.

According to LPS’ analysis, the states with highest percentage of non-current loans – which combines foreclosures and delinquencies – are Florida, Nevada, Mississippi, New Jersey, and Georgia.

States with the lowest percentage of non-current loans include Montana, Wyoming, Alaska, South Dakota, and North Dakota.
