Hope this helps,
You are in Chicago. The rules may be different her in North Carolina. Also you know as well as any of us. One of the biggest ways agents get in trouble is by speaking for attorneys about law, speaking for home inspectors and builders when we are not contractors. You should know this. The saying goes ' we are a source of the source but not the source." This means dont speak where our license does not allow us to go. We all may have our own opinions. But opinions are not facts.
Chris, if you are under contract but still under attorney review you can kill the deal for any reason but price. I get attorneys who do this to my listings all the time and "I dissaprove" is all they say because they legally have to offer no further explanation.
If you're out of A/I there is still a chance they will ask for extensions for getting a mortgage. If this happens you can simply refuse and when that day comes and goes your contract is dead.
If on the other hand you're a few days out from closing and these buyers have packed up their stuff and hired movers you're in a totally different situation.
Yes, you can be sued for specific performance but in all likelihood the buyers will go buy one of the other 10 billion properties on the market and be inconvenienced for a few weeks. People don't have the money to be suing eachother these days!
