I think that short sales, as a whole, are handled wrong. Many agents send off every offer to the bank as if they already own the home. They don't, yet. The bank's position is to approve a settlement of the debt, they have approval power. So what I do is tell the listing agent that we will give them a good offer, and open escrow and then wait for bank approval. We put a small deposit into escrow and incur no fees. Then we wait. I also try and get them to use my escrow officer who is a short sale expert and she has been averaging 45 days, start to finish. This way, we are the only offer the bank sees, unless they ask for others, and they see they have a qualified buyer who is in escrow. Makes it easy for them to say "yes."
Hope this helps....if you aren't in escrow, then throw offers out and hope that they come back sometime. Sometimes they do, other buyers might find something else and you'll end up getting it.
