Bull's Property tax

My dad lost my mom of over 30 yrs of marriage on Valentine's day last yr. He's been struggling in many ways and one area has been financially. As many know losing an income hits hard and big bills just can't get paid. One of those Bill's are his property tax on the land that their home is on. He is behind 2yrs and has no way to get caught up and he has nothing to sell to get the money.  My dad is vet and is disabled,  so very limited income.  His health is not the best and I try to do what I can to help. I'm not one to ask for help, I'm the one that tries to help others in many ways. It would break my heart for my dad to lose everything. We as a family would be so very grateful for any help in keeping his property that he shared with my mom and shared so many memories.  Thank you
