Problem 1: Given no one wants to farm it, this problem suggests the farm should be sold.
Problem 2: She was compensated for her work, drew a salary and appears she had room and board. I would view this as no different than anyone else who had a job, and finds them self out of work. It has no bearing on the financial aspects of the sale of the farm.
Problem 3: This simply means the house doesn’t add much to the sale price of the farm. Have an independent appraiser determine the value of the property and put it on the market at that price. If a sibling wants to buy it, they can. The net proceeds from the sale are distributed among the heirs.
You need to view this a a purely financial matter and keep any and all emotion out of it.
Thank you.
Sound advice. Unless you can consent for it to be farmed/sharecropped, selling it will return the land to productivity.
