It hasn't sounded that you are "IN LOVE" with the farm or the "farming way of life" from other posts that I have seen. So I have a suggestion if no one in your family, children or grandchildren, even nieces or nephews is interested in the place. Find some young person that REALLY wants to farm; has the fire in their belly, and either lease it with a buyout plan, or sell it outright to them with you and your brother holding the mortgage and getting a yearly income. That way there won't be the capital gains taxes, you will have a yearly income that you can put in a Roth IRA if nothing else and your children can benefit from it after you die since there is no minimum age to have to take it out..... There are ways to do it if you don't want to farm it anymore. And maybe some young person will be able to get a start. If something dire happens to them, it can be set up as mortgage holders that you would get it back and then it could be sold conventionally.
I have always regretted that my family did not care enough to want any of us to carry on the farming tradition. My son and I have worked our butts off to establish our own farming life and have listened to several different ones over the years, deride us for all the hard work for no big money gain. You have to love it, some days hate it, sometimes just say 'why are we doing it?', and then keep on keeping on. We would have given our eyeteeth to have had some family support, or an older farmer that cared enough to not want it to get developed and given us a little break. We made our own, and some days we still wonder if it is worth it, but we mostly believe it is. And we hope to find someone who will believe in it as much, to pass it on to, if he never finds the right girl to marry and have kids with. My nieces and nephews are all into money and "things" way too much.... I may hurt and feel the hard years but I am mostly content when I see a new calf or a field of nice hay waiting for me to get raked and baled. And I "became" a southerner by adoption to realize these dreams.
