Success with short sales is NOT dictated by the area where the house is located.
There are other factors that determine short sale success.
Here are a few of them:
1) Lender - is the lender willing to approve the short sale?
2) Number of trusts involved - two loans is harder than one
3) Seller must be able to prove a genuine HARDSHIP - being merely unhappy with the current market does NOT qualify the seller for a short sale
4) Willingness of the Seller to cooperate - providing documents in a timely manner
5) Keeping the house buyer ready all the time, as in a traditional sale, in order to bring the best possible offer
6) Finally, the listing agent's comfort level with the short sales
I am a REALTOR with three short sale designations: SFR, CDPE, and CHRE. I would be happy to meet with you to discuss short sales in more details and your chances of being approved.
Short sale affects your credit scores for 18-24 months, while foreclosure affects those scores for 5-7 years.
If you can, give a short sale a chance - unless, you can work out something with your lender an modify your loan.
