Nothing you can really do. If you have an attorney he or she can call a lot but that really won't matter. The best thing you can do is practice patience. My wife and I are going through the same thing right now. What we did is put an offer on 2 properties. 1 was a short sale. 1 is a regular sale. We really liked both properties. Being in the business, I know good and well this short sale can take forever so I wanted to cover my bases.
Well the offer got accepted on the normal sale and the bank is still screwing around with the short sale. They only have about a week left for the contingency date on the short which there is no way they will make. So, I will get my earnest money back on the short sale and my loan is almost done on the normal sale.
If you can afford the multiple earnest money deposits, you may want to consider not putting all of your eggs in one basket.
