Despite reports showing that many homeowners lack required flood insurance policies, Fannie Mae and Freddie Mac said data show that most of their loans do have the appropriate coverage. Recent hurricanes in Houston and Florida revealed that borrowers either never had coverage or let their policies lapse. Flood insurance is a requirement for GSE loans in designated flood areas and the mortgage giants say that servicers are responsible for enforcing the policies. Nevertheless, getting to the root of the disconnect is complicated. Although the GSEs said it’s up to servicers to evaluate whether loans meet flood insurance requirements, they said they also have their own systems in place to help ensure compliance.
