A growing share of loans with high debt-to-income ratios and other high risk factors has recently concerned mortgage insurers and prompted a policy change at Fannie Mae.

Mortgage insurance companies began to notice that too many borrowers were being approved who exhibited additional risks factors such as weak credit scores and inadequate reserves.
