Idaho rules for small claims allow the Plaintiff to file in the county in which the matter arose (in this case, apparently that would be where the property is located) when the Defendant (you) lives out of state. If the buyer really files an action, versus simply threatening one, then yes, the Plaintiff will get a default judgment against you if you do nothing, However, most courts will allow you to defend yourself over the telephone if you request it. You haven't indicated the location of this matter, so I cannot swear that the court you would be in would allow you to defend yourself by phone, but I suspect they would under the circumstances. You'd mail them any paperwork you wanted to use in your defense ahead of the hearing.
