Can you file a lien against your neighbor's house if she let a 16-year-old drive her car and she destroyed your fence and neither has insurance and her house is for sale and she has moved?

Don't you have insurance? Perhaps your homeowners policy will cover the damage to your fence. Another alternative would be to sue your neighbor in small claims court. If the amount of damage exceeds the small-claims limit, you may have to bump your case up to the next level of civil court. And are you sure the car wasn't insured? yes, better hurry.
