As part of the short sale, you will not receive any money, as stated below by other Realtors. The bank will eat the difference of what you owe on the mortgage and what you get for the sale of the property. They will pay the Brokerage fees and will even pay the movers. Bottom line on the HUD, you get nothing.
If the home is a primary residence, you will not have to pay taxes on the shortcomings up to $2 million. That federal law HR? I don't have the number in front of me at the moment. You can email me for it, if you wish and see for yourself. And, your credit is not nearly as affected as it would be if the bank repossesses on a foreclosure. You can qualify for FHA immediately after a short sale.
Consult with a local FL attorney who specializes in short sales to be sure, as this is what I was taught at a short sales seminar in NJ.
