If a closing is pushed back with no signed agreement can the seller cancel the contract?

All real estate sale agreements state that time is of the essence.  Accordingly, all deadlines must be strictly met, unless the parties agree to an amendment which is often accomplished through an addendum.  The seller has no obligation to move the closing date and failure to close is a default allowing the seller to sue for the deposit. I trust that answers your question, and if you are in the Delaware Valley, feel free to call or email on a free initial basis. Best Regards,   Matthew R.
