The National Association of Realtors recommended that the Federal Housing Finance Agency create what it called a “mortgage market liquidity fund” as a way to allow Fannie Mae and Freddie Mac to rebuild capital. In a letter that went out this week to Federal Housing Finance Agency Director Mel Watt and copied to the Treasury, the trade group expressed concerns about the dwindling capital buffer that’s scheduled to hit zero by Jan. 1, 2018.If Fannie and/or Freddie posts a loss, they will need to tap a line of credit with Treasury. And with no capital reserves, NAR said that the taxpayers will feel the impact while access to credit and homeownership will be stifled.
