I'm sure you've already checked this but I'll comment anyway. Make sure there is something under the paneling! this may sound absurd but our home interior is covered in paneling and nothing else. Since we bought the house 3 years ago we have been pulling it down, putting up insulation with vapor barrier and then drywall. For what we paid, we didn't think we were getting a "handyman's dream". Still love the house, property, etc, but we are definitely wiser.
