Cobb, an unmarried individual, had an adjusted gross income
of $200,000 in 2012 before any IRA deduction, taxable
social security benefits, or passive activity losses. Cobb incurred
a loss of $30,000 in 2012 from rental real estate in which he actively
participated. What amount of loss attributable to this
rental real estate can be used in 2012 as an offset against income
from nonpassive sources?
