With millions of Americans out of work and struggling to pay their rent, the federal government is offering landlords a break in the hopes it will avert a tidal wave of evictions.

The Federal Housing Finance Agency announced on Monday that landlords with government-backed mortgages are eligible for an additional three months of mortgage forbearance—provided they don’t evict tenants who can’t pay their rent during that time.

The extension is designed to trickle down to renters by taking the pressure off landlords who are on the hook for their own monthly mortgage payments.

The forbearance is only for owners of multifamily properties of five or more units who have mortgages backed by Fannie Mae and Freddie Mac.

Nearly six million properties across the U.S. have a substantial risk of flooding that isn’t disclosed by federal flood maps, according to a nonprofit research firm that released its own U.S. flood maps Monday.

Homeowners, developers and city planners have long used the Federal Emergency Management Agency’s flood maps, which outline flood zones. FEMA’s maps label which properties have at least a 1% annual risk of flooding, also called a 100-year flood zone.

The First Street analysis suggests that millions of American homeowners could be more vulnerable to flooding than they realize, and many may lack the resources to rebuild their homes in the event of severe flood damage. Mortgage lenders typically require buyers
