Final answer:
Curry's initial basis in the partnership interest is $18,000.
Step-by-step explanation:
To determine Curry's initial basis in the partnership interest, we need to consider both the adjusted basis and fair market value of the asset contributed. In this case, Curry contributed land with an adjusted basis of $30,000 and a fair market value (FMV) of $57,000. However, we also need to account for the mortgage of $12,000 that was assumed by the partnership. Therefore, Curry's initial basis in the partnership interest would be the adjusted basis of the contributed asset minus the assumed mortgage: $30,000 - $12,000 = $18,000.
