Home mortgage foreclosure rates in the Baltimore area were up in August over the same month last year, according to recent data from housing market analysis firm CoreLogic.

Among outstanding mortgage loans in the Greater Baltimore area, 4.24 percent were in some stage of the foreclosure process in August, CoreLogic said. That’s an increase of 1.58 percentage points when compared to August 2011, when the Baltimore region’s foreclosure rate was 2.66 percent.

Maryland as a whole had a similar jump in the foreclosure rate, from 2.83 percent in August 2011 to 4.4 percent two months ago.

The national foreclosure rate in August was 3.35 percent, down from 3.46 percent in August 2011, CoreLogic said.

The increase in Maryland’s foreclosure rate is likely driven by a the substantial “shadow inventory” that built up when banks put the brakes on their foreclosure processes in the fall of 2010. At that time, bank became wary of moving forward with foreclosures while they were being investigated for foreclosure-related misdeeds, including “robo-signing.”

A national settlement of those allegations was approved about six months ago, allowing banks to resume their foreclosure activities.

Maryland’s rate of extreme mortgage delinquency also increased slightly in August.

Eight percent of mortgage loans were 90 days or more delinquent, CoreLogic’s report said. In August 2011, the 90-day delinquency rate was 7.17 percent.

In Maryland, the 90-day delinquency rate was 8.24 percent during August. Nationally, the three-month delinquency was 7.76 percent.

Among Baltimore and its six surrounding counties — Baltimore, Anne Arundel, Howard, Carroll, Harford, and Queen Anne’s — only small portions of Howard and Anne Arundel counties had foreclosure rates below 1.5 percent.

Nationally, the 90-day delinquency decreased from 7.19 percent in August 2011 to 6.76 percent this August, CoreLogic concluded.
