I’m cheating and did not read the entire thread. I believe there may be an out in Georgia’s conservation use program that allows for carving out small parcels to close family members for homesites. I would recommend checking with your county’s tax assessors office.
My dad once gave my brother a corner lot on the farm to build his first home on. They quickly outgrew it, so ’daddy may I have another?’ Ok on House #2.
I’m the farm trustee now and they wanted to downsize recently, 30 years later. Grrr, don’t even ask.
