Becky bought the home with her husband, Ken, in 1997 for $125,000. They were divorced in 2006 and Becky became sole owner of home under the divorce decree. On January 5, 2010 Becky married Michael. Michael and Becky have been living in house since their marriage but they're planning now to move. If Michael and Becky sell their home on December 15, 2012 for $500,000, how much taxable gain should they report upon their 2012 joint tax return?
