The secretary of the U.S. Department of Housing and Urban Development has outlined a plan to Congress to increase premiums for borrowers with small down payments and decrease loan-to-values for borrowers with poor credit scores.

The housing agency is requesting authority for the Federal Housing Administration to insure $420 billion during fiscal 2011, which begins on Oct. 1.
