Last year, Ricardo sold a piece of unimproved real estate to Cliff for $20,000. Ricardo acquired the property 15 years ago at a cost of $10,000. Last year, Ricardo received $4,000 cash and Cliff’s note in the amount of $16,000 for the remainder of the selling price, payable in subsequent years. Ricardo reported the sale using the installment method. This year, before Cliff made any further payments, Ricardo sold the note for $15,000 in cash. What is the amount of gain or (loss) Ricardo should report on this year’s tax return?
