Prior to this, how often were homes sold to FHA buyers that were also purchased within 90 days prior to that FHA purchase ?
I think this is only a major problem for the commercial flippers (e.g. Bruce Norris) who have the machinery in place to rehab properties within 30 days or less. Still, they have to market and get it sold.
It is not really a removal of buyers from the pool, more like a removal of available properties and an increase in the time (and therefore money) required by the flippers.
