Short Sales

Short Sales are absolutely the most frustrating of all Real Estate transactions I have encounter.  I have been involved in a few but this latest deal gets me to wondering if the personnel on the bank side have any idea of what they are doing.  I went to a seminar provided by a business that helps negotiate short sales and was told that on several occasions banks were made offers that were reasonable, refused them and let that property go into foreclosure, were it sold for far much less than the price offered by the buyer who wanted it when it was a short sale?  All that tells me is that banks/lenders are in desperate need of a new system or more savvy/qualified people on their end facilitating these transactions.  In my current transaction, the third lien holder is arguing about the 2.5% commission to each agent, unbelievable!
