1. Taylor sold land held for investment for $40,000 on December 31, 2020. The land was purchased three years earlier for $25,000. The sales agreement required a down payment of $10,000 and installment payments of $10,000 principal each year for 3 years (12/31/21, 12/31/22, and 12/31/23), plus 6% interest each year on the unpaid balance (so Taylor received interest of $1,800 on 12/31/21, $1,200 on 12/31/22, and $600 on 12/31/23). During 2020, Taylor also sold Best Buy Corporation stock for $7,000, which she acquired five years earlier for $19,000. Considering each year separately, what impact will these transactions have on her 2020, 2021, 2022, and 2023 income (specify dollar increase/decrease in taxable income each year and character of such increase/decrease).
