Sorry to hear, but it does not suprise me.
My good friend is buying her first house a 2 bedroom condo next week. It is less than 10 years old and when sold new it was $229,000. It was listed at $129,000 and she went under contract at $99,000, the only problem it did not appraise. She is now purchasing it for $75,000. She is super happy, but if I were the sellers I'd be sick.
