re: Backing out of Purchase Agreement

Just so you are clear, if you take this to probate and tie up in the system no one will touch your house with a ten foot pole. This will not be resolved overnight. You could potentially lose as the buyer may convince they were acting within good faith and did notify you within the period albeit not in writing. If an email was submitted within the period that may work as well.

Court is hell. Go after their earnest or % of it. Sell it to someone who wants it.
