Options when sellers delay closing

[Rob Pagarigan]

We are 1 day away from closing a real estate deal. The sellers and seller's agent have been extremely difficult to work with throughout the deal. We signed the docs yesterday and just after that, we were notified by the seller's agent that the central A/C went out the day before. They said the were going to have their home insurance policy cover it and they had already paid the deductible, but getting any other information has been difficult to get because they aren't answering my agent's specific questions. The only thing we know is that an adjuster is coming in the next couple of days.

I am not willing to close the deal until I have confirmation of the repair being completed or a paid receipt and/or verified date for repair to be made.

If they continue to drag their feet, what are my options assuming I may have to re-lock on my rate or delay closing?
