Maryland had the nation’s highest foreclosure rate this spring, a new survey has found, and the flood on the market could drag down home values in the state.

Nearly 2 percent — or 20,000 — of Maryland’s 1.1 million loans included in the survey were moved into foreclosure between April and June, according to a new survey by the Mortgage Bankers Association. The rate was nearly double the national average of about 1 percent of all home loans.
