Fannie Mae owned 67,500 properties in foreclosure at the end of September, according to the company's most recent filings. Most of those were owner-occupied. Under the new policy, former owners will most likely not be eligible to rent homes they lost in foreclosure. Last month, both Fannie Mae and Freddie Mac, the other government-controlled mortgage giant, temporarily suspended foreclosures and evictions until early January. Fannie Mae will now offer renters in foreclosed properties month-to-month leases until the property is resold. A company representative said program details were still being worked out.
