My grandparents bought a 7.5 acre farm in 1921 for $20,000. They
had six children. My grandfather died in 1958 and my grandmother in
1992. My father, their son, died in 1993. The land sat idle and was sold
in 2017. The proceeds were divided by 6 and my father's portion
divided by 3 of his children. We have a form 1099-S. But we don't know
how to find the FMV of 1993 when we inherited the land from our father.
How do we show this on our taxes?
