I was deeded some land from my grandparents in 1982 while they were still alive. It had mine and three siblings names on one section of land. I am now selling my shares to my sister. The amount we agreed on is below the taxable value. Do I pay capital gains on the amount I was paid minus the amount it was worth in 1982? Also do I still have to pay the real estate taxes for the next year after I sell it?
