Short Sale Approval Home Financing Center

I just received a short sale approval from Home Financing Center. This turned out to be a very long process. They have 1 employee handling their short sale negotiations. That position changed 3 times throughout the process, which means we the process started over each time. Finally after 7 months under contract they asked the seller for a large promissory note and cash to close. After intense negotiations they finally removed this requirement and they are waiving the right for a deficiency.
