When you sell a second home, the title company will mail you a 1099-S. That proceeds amount on 1099-S needs to match the Proceeds on form 8949 under box d.
For the cost (box e), is that the cost of you paid originally for the home? What if I add an air conditioner would that amount be added to "Cost or other basis"?
Also, if you sold a home and you need to pay the agent commission, is that amount added to box g "Amount of adjustment" with code E?
