The Treasury Department said the so-called GSE patch gives Fannie Mae and Freddie Mac an unfair advantage in the mortgage market, and it recommended eliminating this exception to the qualified-mortgage rule. In a financial regulations report released this week, the Treasury detailed a host of executive actions and regulatory changes that it believes can immediately stimulate economic growth, increase capital access and protect taxpayers. Adjusting and clarifying the ability-to-repay/qualified mortgage rule and phasing out the GSE patch are among those changes listed. The GSE patch, created under Dodd-Frank, allows GSE eligible loans to qualify for QM status, even if the DTI exceeds the standard 43 percent ratio.
