Gary is correct. You need to discuss this with all parties involved in the contract through your respective attorneys. However, the reason you sited here, not being ready to move, makes me throw caution your way, and your attorney will advise of such also. Most closing dates can be moved up or back within reason. When you signed the contract you entered into that agreement on good faith that you could perform the sales contract as written. Requesting a change in the closing date is modifying the agreed terms of the contract. Unreasonable delays could become a problem for you: just because you ask everyone for an extension on closing does not guarentee that the buyers will grant your request. The buyers may have issues on their side whereby their landlord or their buyers must have possession by a certain date. Be prepared that YOU may have to be the one to find temporary housing. As Gary suggested, contact your attorney and your designated agent.
