The Federal Housing Finance Agency captured the industry’s attention this week by formally citing “significant concerns” about proposals to use local government eminent domain powers, a paradigm shift the agency sees as potentially costly to Fannie Mae, Freddie Mac and the Federal Home Loan Banks. In a request for public comment, published in the Aug. 8 Federal Register, the Finance Agency warned that “action might be necessary” on its part “to avoid a risk to safe and sound operations” at the GSEs and to avoid taxpayer expense.
