My mother(65yr old) had inherited a house from her maternal side which she sold in 2012.She invested a part of the proceeds in a land and a house in the year 2013.She had taken some loan from relatives during the construction of the house.Now she wasnts to sell off the land and construct a top floor on the house and pay off her debts. Will she be eligible for Exemption on Long Term Capital Gain Tax?It may be noted that she had only one residential house in 2012 and even now she has that single house which she purchased in the year 2013
