FHA instituted the anti-flipping rule in 2003 to protect its mutual mortgage insurance program from losses on homes that were merely flipped, rather than rehabbed. Homes repossessed by Fannie Mae, Freddie Mac, and state- and federally chartered financial institutions were exempt from the rule.

In February 2010, the Obama administration waived the waiting period for resales — including homes purchased and rehabbed by private investors — in the hopes of stabilizing home prices and revitalizing communities hit by foreclosures.

It often takes less than 90 days to acquire, rehabilitate and sell properties, the Department of Housing and Urban Development said at the time. Some sellers of rehabbed properties had been reluctant to enter into contracts with FHA buyers because of the cost of holding a property for 90 days, HUD said.
