Christy contributes land $($FMV $=$ $$50,000,$ basis $=$ $$30,000)$ to the ABC partnership, and four years later gets a distribution $($that was not assured at the time of the original contribution$)$ of another piece of land $($FMV $=$ $$60,000,$ basis $=$ $$50,000).$ Her basis in the partnership interest immediately before the distribution is only $$55,000.$ Assume that she has not contributed any more properties to the partnership, so her net precontribution gain is still $$20,000($the unrealized appreciation on the property she contributed$),$ and has been for four years. What will be her basis in the partnership after the distribution?
