With 120 acres of woods, the land should be eligible for
New York's Forest Tax Law Program (480-a), which lower property taxes up to 80% in exchange for following a management plan written by a forester. That would be a good short-term solution to get the taxes down. Longer term, they might want to look into tools for how to pass the land down to your friend (and any other heirs). That's a lengthy process, but it can really help avoid family strife and tax issues down the road when the property eventually changes hands. I recommend the "
Leaving a Legacy" area of MyWoodlot for advice on getting that process going and resources to help your friend and her family.
