CFPB Director Kathy Kraninger says the relatively small size of the non-qualified-mortgage market is one of the reasons the bureau plans to change QM standards.

Certain non-QM lenders’ underwriting tactics might not meet the CFPB’s ability-to-repay rule, according to Moody’s. It suggested tighter standards for bank statement mortgages and loans to the self-employed.

Annaly Capital Management and Ellington Financial are both generating double-digit returns from aggregating mortgages and issuing non-agency MBS. The firms plan to increase their activity in the sector.
