I did think of the parceling, but the way it is three siblings have homes/large lots on one side of the property so any parcels would be sort of useless as there is no frontage. There is frontage that could be sold.
I feel for you. That is tough. As one of my relatives said when talking about distributing family property... “There is ONE in every family.” In other words, someone makes trouble and seems to want everything. (Not my situation)
Sell the farm. Split the proceeds and move on. Can the house be moved? We have flag pole properties here. Little frontage but property in back.
