Corey sells raw land to Anna for $300,000. Corey has held the land for 15 years, and the land has a basis of $200,000. In the current year, Corey receives $50,000 and a note for $250,000. Anna agrees to pay the note every April 15 for 10 years at $25,000 principal plus 10-percent interest. 

What does Corey report on his income tax return in the year after the sale when he receives the required payment of $50,000 (which includes interest income)?
