Golf club membership with Capital gain
I joined a golf club 21 years ago for $35,000. I sold the membership this year For $63,000.
During that time we put in an irrigation system, new club house, expansion of the new club house, multiple hurricane, new greens x2, new sand traps etc.
Question
1. Is the gain from selling the membership taxable?
2. Is there a cost basis with all of the assessments over the 21 years. that increase my cost above the $35,000?
