Kacey sells a commercial building and receives $50,000 in cash and a note for $60,000 at 10 percent interest. Kaceys adjusted basis in the building on the date of sale is $45,000 and they collect only the $50,000 down payment in the year of the sale. Assuming Kacey uses the installment sale method, calculate the taxable gain they must report for the year of the sale.
