buying short sales

How do short sales work? What are the down sides about buying a “short sale” home?
The biggest down side is that it can take months.
Also, the home owner may not have actually cleared the sale with the lender first. It is entirely possible that the sales price is a bait and switch. Low enough to get you interested, but even at full price there is no possible way the bank will agree to the sale.
