It really depends on the bank, property, offer, negotiator, etc. In my personal experience I seen them vary between 3 months and 10 months; however I heard of some taking much longer. I always encourage my clients to avoid short sales whenever possible, unless you are in no rush whatsoever. It can be very frustrating once it falls into the bank's " Black Hole". When they do eventually get back to you, they may approve it, disapprove it or ask for more. Quite often the first short sale bidder is the "guinea pig" to see what true amount the bank is willing to sell it for.
