I recently joined with a group of neighbors to contribute money to buy a piece of property back from a developer who wanted to build apartments on a very small piece of property in our neighborhood. One person paid the bulk of the amount, so the rest of us just donated the money we contributed to his acquisition of the property. He is the sole owner now. My contribution was $5k. How do I report that on my taxes for this year? I was asked by the real estate office to complete a tax form for the amount I contributed. I live in WA state.
