Fannie Mae closing issue

[John Ewas]

I was Highest and best offer on a Fannie Mae property. I included 20k earnest money, all contracts were accepted and signed in Sept, with Closing date scheduled for this past monday, Sept 29

My closing atty notified Fannie's attys the week before closing that they needed to complete paperwork. They never did the paperwork or filed it at the Registry of Deeds.

 Can I get any $$$ from them for their non performance and breach of contract ?  maybe $50-100 day ?  They want a 30 day extension, which I'm reluctant to do, but will do as the house will be a profitable rehab.

Any body had this happen ?
