Big Dar - I've read your last 2 questions and it appears to all of us that you do not understand what is involved in a short sale if you keep on asking "how much will it cost me?".
In a short sale, the lender that you owe the mortgage to is agreeing to accept less than what they owe, because you cannot sell it for the amount you owe on it AND you are unable to bring in the difference, so they agree for you to "short" them in the sale.
The lender that you are shorting may or may not have a requirement for you to bring in money to the transaction, it is not the same situation for every person, that is why you are not getting answers with a specific amount, because the answer is no one knows for sure. Most people who do a short sale don't have to bring in any money, which is why many people are saying "None".
Additionally, you probably cannot sell your home to someone that you know, it has to be a completely disinterested party.
Do you fully understand what a short sale is, how it's handled, and what requirements there are for your own mortgage lender approving you to short them on the amount you owe?
