Maddie owns a home that she inherited from her grandmother, Paula, seven months ago. The fair market value of the house at the date of Paula's death was $$475,000.$ Her grandmother paid $$27,000$ for the home in $1960.$ Based on an appraisal, the house is currently worth $$520,000.$ If Maddie sells the house for its appraised value, and pays $$31,000$ to a real estate agent, what is Maddie's realized gain or loss.
