Buyer Won't Settle at Crescent Condo In Downtown Silver Spring

Buyer won't settle at Crescent Condo In downtown Silver Spring. Check out this posting on Craigslist:

Can someone pls recommend a real estate atty. The Crescent Condo in Silver Spring people are telling me that I'm in breach of contract because I didn't go to settlement. But the reason I didn't go to settlement is because their own people told me not to when the appraisal came in 60k under the contract price. They lied. I need help to terminate contract and get deposit back. Can anyone help?

Maybe Lance will buy this condo?
