So I have inherited these mineral rights (don’t own the property). In actuality, I own 1/4, my brother owns 1/4, and my step aunt owns half of 140 acres mineral rights only. So they had a hard time finding us, talked to my sister inlaw and the offer was 70k to buy, then they talked to my Alzheimer’s father who went on and on about how the property was so worthless and all we had ever gotten out of it was a 500$ lease. Now the offer is 7k (supposedly a decimal point error about the number of acres). If it were a lease, not the end of the world but they want to buy. I know there are oil layers but for such a small deal, and wont they try to take as much as possible just to advise?
