Sale of Real Estate

My mother is 79 years old, and I am her guardian. I sold her house for $160,000.00 in November 2011. She and my father bought the house in 1973 for $45,000.00. In 1986, my parents divorced.

My mother paid my father $40,000.00 to transfer ownership to her. Over the years, she added an eclosed porch, replaced the roof, both bathrooms, and resurfaced the driveway.

There are no records of anything except for the sale of the house this year. What should I expect my mother to have to pay in income tax on the sale?

Thnaks,
